Typical Problem in the Conventional Systemand their Solution by using MPCBShort-Circuit Breaking CapacityWhen numerous small and medium motor loads exist in a circuit requiring high breakingcapacity, there is no high breaking capacity circuit breaker with a small rated current for ashort circuit protection.The MPCB can be used in 100kA short circuit current circuits for three-phase, 240Vmotors with rated capacity upto 15kW, and in 50kA short circuit current circuits for threephase, 415V motors with rated capacity up to 30kW.Back-up breaking systemWhen back-up MCCB is installed upstream to solve the problem described in “ Shortcircuit breaking protection ” above, a short in one of the load circuits also trips theupstream breaker and stops the other operating circuits.Despite their compact size, the MPCB provides high-performance short-circuit currentbreaking. They eliminate the need for an upstream circuit breaker for back-up use.Overload ProtectionMotor Protection breakers cannot be adjusted to match the rated current of the motorbeing protected.Equipped with a wide range current adjustment dial (with maximum/minimum ratio of 1.4to 1.6), the MPCB easily adjusts to match the rated current of the motor, for optimumprotection.Control Panel SizeConsiderable space is required to install a back-up circuit breaker or a combination starterconsisting of a circuit breaker and a thermal overload relay. As a result, the panel size hasto be increased.The compact size of the MPCB, including overload relay functions, enables a smallerinstallation area with less wiring space, for a reduction in panel size.4
