The 630A Molded Case Circuit Breaker with LCD Display is a protective device used in power systems to protect circuits from overload, short circuit, ground fault, etc. This circuit breaker has the characteristics of high breaking capacity, strong reliability, safety and reliability, and is widely ......
Read MoreMolded case circuit breakers are also known as shell circuit breakers. It is a terminal with a plastic casing enclosing the internal connection network, which has a very low discharge resistance and protects the device from moisture or dust in a wet environment.
Read MorePlastic case circuit breakers (hereinafter referred to as circuit breakers) are generally used for power distribution and can also be used to protect motors. Under normal circumstances, the circuit breaker can be used for infrequent switching of lines and infrequent starting of motors.
Read MoreAir circuit breaker is a kind of circuit breaker. The insulating medium is air. It is a low-voltage switch with manual (or electric) closing, a lock to maintain the closing position, a tripping mechanism to trip and an arc extinguishing device. It is currently widely used in AC and DC devices below ......
Read MoreMolded case circuit breakers are also air circuit breakers. Commonly used air circuit breakers include frame circuit breakers and molded case circuit breakers. The former has a large capacity, a large rated breaking current, and a large volume, so there is no plastic case, and all parts of the circu......
Read MoreThe main contact of the low-voltage circuit breaker is closed manually or electrically. After the main contact is closed, the free tripping mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected in se......
