Circuit Breakers: 483-G411-K1M1-A1S0Z-7.5A

A circuit breaker is an electrical component that is designed to protect an electrical system typically from overloads or short circuits. It’s a form of switching device which can be either manually operated or automatically operated. The type of circuit breaker covered in this article is 483-G411-K1M1-A1S0Z-7.5A, which is an all-in-one package designed for low voltage distributed protection.

Application Field and Working Principle of 483-G411-K1M1-A1S0Z-7.5A

The 483-G411-K1M1-A1S0Z-7.5A applies to AC 50Hz, rated operational voltage of 0.45kV/1.5kV and the rated current of 400A. It primarily used in medium and low-voltage power distribution systems of various institutions, factories, mines, high-rise residences and other places.The 483-G411-K1M1-A1S0Z-7.5A working principle involves three conditions which all cause the circuit breaker to open. The first condition is an overload current which is higher than the rated current. When an overload current is present, the bimetal strip will heat up due to the Joule heat. This causes the bimetal strip to bend and push the operating linkage of the breaker, thereby causing the breaker to open. The second condition is an instantaneous short circuit current that is usually greater than the preset limit for the breaker. For this condition, the breaker will also open. The third condition that can activate the circuit breaker is an instantaneous overvoltage, which is usually caused by a thunder strike, or other fault in the system. This condition will also cause the circuit breaker to open. When all of the conditions are within the prescribed limits of the breaker, the circuit breaker remains closed. The 483-G411-K1M1-A1S0Z-7.5A consists of several components such as the circuit breaker frame, operating handle, operating mechanism, contacts, switchgear, etc. to facilitate the protection of an electrical system.

Advantages of 483-G411-K1M1-A1S0Z-7.5A

The 483-G411-K1M1-A1S0Z-7.5A offers several advantages, including: * Long life: the contact systems of this circuit breaker are designed to withstand overloads that would normally damage conventional breakers.
