Masterpact NT and NW Universal Power Circuit BreakersMasterpact Circuit BreakersIntroductionMasterpact NT/NW Universal Power Circuit Breakers are designed toprotect electrical systems from damage caused by overloads, shortcircuits and equipment ground faults. All Masterpact circuit breakersare designed to open and close a circuit manually, and to open thecircuit automatically at a predetermined overcurrent setting.Masterpact circuit breakers can also: Enhance coordination by their adjustability.Provide integral ground-fault protection for equipment.Provide high interrupting ratings and withstand ratings.Provide communications.800–1600 A Masterpact NTDrawout Circuit BreakerProvide power monitoring.Provide protective relaying functions.Provide zone-selective interlocking (ZSI) which can reduce damage in the event of a fault.Masterpact NW Drawout Circuit Breakers0613346906133468Figure 1:NX 08HA10 12kVUimpUi 1000VUe (V)69050kA/1s50/60HzAS947-2UNEIECBS CEIEN 60947-2VDEUTENBMA800–3200 A Masterpact NW Drawout Circuit Breaker4000–6300 A Masterpact NW Drawout Circuit BreakerCodes and StandardsMasterpact circuit breakers are manufactured and tested in accordance with the following standards:Low-Voltage PowerCircuit BreakerInsulated CaseCircuit BreakerIEC RatedCircuit BreakerIEC Extreme AtmosphericConditionsANSI C37.13IEC 68-2-1: Dry cold at –55 CANSI C37.16UL 489 (UL Listed)ANSI C37.17NEMA AB1IEC 60947-2ANSI C37.50CSA 22.2 No. 5092IEC 60947-3UL 1066 (cULus Listed)NMX J-266-ANCEIEC 68-2-2: Dry heat at 85 CIEC 68-2-30: Damp heat(temp. 55 C, rel. humidity 95%)IEC 68-2-52 Level 2: Salt mistNEMA SG3NOTE: Throughout this document, the phrase “ANSI Certified” means the product meets the requirementsof UL 1066 and ANSI C37. When “UL Listed” appears, the product meets the requirements of UL 489.The 800–2000 A ANSI Low Voltage Power Circuit Breakers type L1F and Insulated Case CircuitBreaker type LF are tested to show the arc flash hazard risk category as referenced by NFPA 70E.Circuit breakers should be applied according to guidelines detailed in the National Electrical Code (NEC ) and other local wiring codes.Masterpact circuit breakers are available in Square D , Merlin Gerin , or Federal Pioneer brands.UL File Numbers: Masterpact NW: E161835 Vol. 2 Sec. 1Masterpact NT: E161835 Vol. 2 Sec. 24 2000–2008 Schneider Electric All Rights ReservedCourtesy of NationalSwitchgear.com04/2008
Masterpact NT and NW Universal Power Circuit BreakersMasterpact Circuit BreakersFeatures and BenefitsHigh Ampere Interrupting Rating (AIR): ANSI Certified Masterpact NW circuit breakers have aninterrupting rating of 200,000 A at 508 Vac without fuses.High Short-Time Current Rating: Masterpact NW circuit breakers have exceptional short-timeratings—up to 100,000 A.100% Rated Circuit Breaker: Masterpact circuit breakers are designed for continuous operation at100% of their current rating.Reverse Fed Circuit Breaker: Masterpact circuit breakers can be fed either from the top of the circuitbreaker or from the bottom.True Two-Step Stored Energy Mechanism: Masterpact circuit breakers are operated via a storedenergy mechanism which can be manually or motor charged. The closing time is less than five cycles.Closing and opening operations can be initiated by remote control or by push buttons on the circuitbreaker front cover. An O–C–O cycle is possible without recharging.Drawout or Fixed Mount, 3-Pole (3P) or 4-Pole (4P) Construction: ANSI Rated, UL Listed and IECRated Masterpact circuit breakers are available in drawout or fixed mounts, with either 3P or 4Pconstruction.Field-Installable Trip Units, Sensor Plugs and Accessories: Trip units, sensor plugs and mostaccessories are field installable with only the aid of a screwdriver and without adjusting the circuitbreaker. The uniform design of the circuit breaker line allows most accessories to be common for thewhole line.Reinforced Insulation: Two insulation barriers separate the circuit breaker front from the current path.Isolation Function by Positive Indication of Contact Status: The mechanical indicator is trulyrepresentative of the status of all the main contacts.Segregated Compartment: Once the accessory cover has been removed to provide access to theaccessory compartment, the main contacts remain fully isolated. Furthermore, interphase partitioningallows full insulation between each pole even if the accessory cover has been removed.Front Connection of Secondary Circuits: All accessory terminals (ring terminals are available as anoption) are located on a connecting block which is accessible from the front in the connected, test anddisconnected positions. This is particularly useful for field inspection and modification.Anti-Pumping Feature: All Masterpact NT and NW circuit breakers are designed with an anti-pumpingfeature that causes an opening order to always takes priority over a closing order. Specifically, ifopening and closing orders occur simultaneously, the charged mechanism discharges without anymovement of the main contacts keeping the circuit breaker in the open (OFF) position.In the event that opening and closing orders are simultaneously maintained, the standard mechanismprovides an anti-pumping function which continues to keep the main contacts in the open position.In addition, after fault tripping or opening the circuit breaker intentionally (using the manual or electricalcontrols and with the closing coil continuously energized) the circuit breaker cannot be closed until thepower supply to the closing coil is discontinued and then reactivated.NOTE: When the automatic reset after fault trip (RAR) option is installed, the automatic control systemmust take into account the information supplied by the circuit breaker before issuing a new closingorder or before blocking the circuit breaker in the open position. Information on the type of fault, e.g.overload, short-circuit or ground fault.504/2008Courtesy of NationalSwitchgear.com 2000–2008 Schneider Electric All Rights Reserved

Disconnecting the circuit breaker is possible without opening the doorand exposing live parts.Racking Handle and Mechanism06133832Figure 2:Door Escutcheon06133341Closing and Opening Push Buttons06133339Racking Handle Storage SpaceRacking HandleT TESTRacking MechanismDisconnectedPositionDrawout Mechanism: The drawout assembly mechanism allows the circuit breaker to be racked infour positions (connected, test, disconnected, or withdrawn), as shown in the figure below.NOTE: For UL/ANSI circuit breakers, the clusters are mounted on the circuit breaker; for IEC circuitbreakers, the clusters are mounted on the cradle.Figure 3:Racking Positions06133830SecondaryContactsStabs (IEC)Clusters (UL/ANSI)Clusters (IEC)Stabs (UL/ANSI)T TESTConnected PositionTTEST06133339Test PositionTTESTDisconnected PositionWithdrawn Position6 2000–2008 Schneider Electric All Rights ReservedCourtesy of NationalSwitchgear.com04/2008
Masterpact NT and NW Universal Power Circuit BreakersReduced Maintenance: Under normal operating conditions, the circuitbreaker does not require maintenance. However, if maintenance orinspection is necessary, the arc chambers are easily removed so you mayvisually inspect the contacts and wear indicator groove (see the figurebelow for how wear is indicated). The operation counter can also indicatewhen inspections and possible maintenance should be done. The life ofthe circuit breaker may be extended by replacing the arc chamber andspring-charging motor and/or replacing the main contact assembly ofANSI Certified circuit breakers.Figure 4:06133470Masterpact Circuit BreakersArc ChamberContact Wear IndicatorsWear Indicator Groove06133185aWear Indicator GrooveGoodContactsWornContactsOperating ConditionsMasterpact circuit breakers are suited for use: At ambient temperatures between -22 F (-30 C) and 140 F (60 C).At altitudes 13,000 ft. (3900 m).Masterpact circuit breakers have been tested for operation in industrial atmospheres. It isrecommended that the equipment be cooled or heated to the proper operating temperature and keptfree of excessive vibration and dust. Operation at temperatures above 104 F (40 C) may requirederating or overbussing the circuit breaker. See the appropriate instruction bulletin and page 15 of thiscatalog for additional information.Masterpact circuit breakers meet IEC 68-2-6 Standards for vibration. 2 to 13.2 Hz and amplitude 0.039 in.
