Schneider Electric's Motor Protection Circuit Breakers (MPCBs) are an essential component of the TeSys series, designed to protect electric motors from various electrical faults.
Function
MPCBs are electromechanical devices that combine the functionalities of a circuit breaker and a thermal overload relay.
They protect electric motors from:
Overloads: Excessive current draw that can overheat the motor windings.
Short Circuits: High fault currents that can cause severe damage.
Phase Loss: Unbalanced loads caused by a missing phase, which can lead to motor overheating and damage.
They also offer manual switching (turning the motor on/off).
