Project Description

FW-CM1 Moulded Case Circuit Breaker

Introduction

MCCB (Molded case circuit breaker) is between air circuit breaker, miniature circuit breaker of a circuit breaker, it in many fields are widely used, such as industrial fields, the field of architecture, water conservancy and hydropower. Molded case circuit breaker mainly installed in low-voltage cabinet used as intermediate distribution using, some in small distribution box or mounted directly on the wall as the direct distribution of some of the load.

Molded case circuit breakers, also known as MCCB, were designed for the purpose of protecting an electrical circuit from becoming damaged.

Application of MCCB

MCCB (Molded case circuit breaker) is between air circuit breaker, miniature circuit breaker of a circuit breaker, it in many fields are widely used, such as industrial fields, the field of architecture, water conservancy and hydropower. Molded case circuit breaker mainly installed in low-voltage cabinet used as intermediate distribution using, some in small distribution box or mounted directly on the wall as the direct distribution of some of the load

MCCB with air circuit breaker and leakage circuit breaker, generally has three types, one with short circuit and overload protection function. Two, with leakage protection function. Three, with short circuit, overload, leakage protection function. Can protect lines and power equipment from damage.

With overcurrent tripping device, undervoltage release (or delay), shunt tripping device, locking and tripping device. Appropriate decision switch, general protection transformer and large capacity power distribution line. With the handle, the lever, the electromagnet, the motor, the air pressure, the hydraulic energy storage type, the non energy storage type and the intelligent operation and so on.
