Circuit breakers are important components of power systems, and their proper operation ensures the safe and reliable operation of power systems. IELHK11-1REC5-70299-100 is a kind of circuit breaker, and this article will describe its application field and working principle.

IELHK11-1REC5-70299-100 circuit breaker is a type of moulded case circuit breaker (MCCB). It is generally used in power systems with rated current of 125A and rated short-circuit breaking capacity of 40kA . It is suitable for the protection of overload and short circuits in buildings, ships, factories and various commercial and industrial places with AC 50Hz/60Hz, rated voltage up to 500V. It can also be used as a motor protector.

The principle of operation of IELHK11-1REC5-70299-100 circuit breaker is as follows. When an overload or short circuit occurs, the thermal element rapidly fuses to cut off the circuit, causing the circuit breaker to trip. When the fault is cleared, the circuit breaker can be reset manually. The breaker also contains a magnetic element. When the current in the circuit exceeds the setting of the current operating device, the magnetic element will immediately cut off the circuit, so as to realize the protection of the circuit. In addition, the IELHK11-1REC5-70299-100 circuit breaker also integrates leakage protection devices for additional protection.

In conclusion, the IELHK11-1REC5-70299-100 circuit breaker has a wide application and is suitable for overload and short circuit protection of AC 50Hz/60Hz, rated voltage up to 500V. It can also be used as a leakage protector. Its working principle is mainly based on the cutting off of circuit by thermal element or magnetic element under high current.
