If the motor does not start, thermal protection trips in response to prolonged inrush current. A high inrush current causes thermal protection to delay the reaction when a motor begins. These devices use a growing and contracting contact to disconnect the motor when an excessive current is detected. Thermal protection-type circuit breakers are used for electric current overload prevention. Thermal protection: In 2016, the market for thermal protection MPCB (motor protection circuit breakers) accounted for 48% of the entire market. The ability of MPCB to withstand starting (flux) currents without disrupting the circuit makes it special.ĭifferent Types of MPCB Circuit Breaker In the Market The maximum short circuit current and the motor's full load current determine which MPCB should be used for a specific electric motor. The MPCBs come in various voltage ranges, typically ranging from about 230 Volts to 660 Volts. The motor is protected against faults by the protection devices circuit breaker (MPCB), a heat circuit breaker. The MPCB is a circuit breaker created to safeguard electric motors from overload, short circuits, under voltage, phase loss, etc. Motor Protection Circuit Breaker is referred to as an electrical MPCB.
