Motor Protectors

An electrical motor is comprised of many parts, including the rotor, coil, casing, seal, to name a few. The motor operates when it connects to a circuit where the current passes through. The current, load, heat, etc. affect the operation of the motor as well as its parts. To protect the motor against damages caused by those factors, the motor protection circuit breaker (MPCB) is required. The MPCB provides the motor with thermal overload protection, short circuit protection, phase loss protection, and controls the on and off of the unit. Sang Mao offers a selection of single and three-phase motor protection circuit breakers. Scroll down to see our products and feel free to leave us a message.
