50 A Mpcb Circuit Breaker

About 50 A Mpcb Circuit Breaker

A Motor Protection Circuit Breaker (MPCB) is a specialized type of circuit breaker designed to provide reliable protection for electric motors against overload, short circuit, and phase failure conditions. It combines the functions of a circuit breaker and a thermal overload relay into a single compact unit, ensuring efficient motor safety and performance. MPCBs are widely used in industrial and commercial applications where electric motors require precise and dependable protection. These devices are designed to handle high inrush currents during motor startup while safeguarding the motor from damage due to abnormal electrical conditions. Key Features Protection against overload, short circuit, and phase loss Adjustable thermal and magnetic trip settings High breaking capacity Compact and space-saving design Easy installation and operation Manual ON/OFF switching capability Specifications (Typical) Rated Voltage: 220V 690V Current Range: 0.1A 100A (varies by model) Frequency: 50/60 Hz Poles: 3 Pole Trip Class: Class 10 / Class 20 Applications Industrial motors and machinery Pumps and compressors HVAC systems Conveyor systems Manufacturing units Agricultural motor protection
