A circuit breaker is a safety device which is used to protect an electrical circuit by automatically switching off the power on overload or short circuiting. Circuit breakers are divided into two types, IEGZXF6-33345-21-V and the other types. This article focuses on the application field and working principle of the IEGZXF6-33345-21-V type breaker.

The IEGZXF6-33345-21-V type circuit breaker is mainly used for the control and protection of low voltage power distribution lines and power end apparatus. It has superior breaking capacity, strong overload and short circuit protection function. It can be used in industrial and mining enterprises, residential buildings, distribution boxes, buildings and other places to control, protect and convert electric energy.

Working principle of the IEGZXF6-33345-21-V type breaker is that when the current of the line exceeds a certain value, the circuit breaker senses the current and trips the circuits. The trip device is triggered by an overload or short circuit current, it is usually operated by means of a bimetallic strip. When a short circuit occurs, the thermal stress of the bimetallic strip rapidly heats and exaggerates, triggering the trip device. When the overcurrent occurs, there is current in the two coils, and the magnetic force produces the torque, and finally moves the operating lever to release the contact, making the circuit breaker open the circuit. After the fault is eliminated, it can be manually reset.

The IEGZXF6-33345-21-V type circuit breaker has superior breaking capacity and strong overload and short circuit protection functions. It has reliable insulation performance, and is equipped with dustproof, moisture-proof and flame retardant casing for safer use. It is widely used in low voltage power distribution systems, and is a key part to guarantee the safe operation of electrical equipment.
