IELZXK1-1REC4-37171-100-V application field and working principle

Introduction: Circuit breakers are important devices used in commercial and residential locations to provide both over-current protection and switching operations in electrical power distribution systems. In this report, the IELZXK1-1REC4-37171-100-V circuit breaker is introduced and its application fields and working principle discussed.

Application fields: The IELZXK1-1REC4-37171-100-V circuit breaker is suitable for use in many applications including general purpose, industrial, and commercial applications in power distribution systems. It is mainly used to provide over-current protection and control operations in AC 50/60Hz single-phase or three-phase circuits, with rated voltage up to 100V. It is also suitable for short-circuit protection in any installation that requires short-circuit current ratings, or in multi-pole applications up to 4 poles. The circuit breaker is designed for both indoor and outdoor installations and can be used in combination with varying types of contactors and relays for additional protections and applications.

Working principle: The working principle of the IELZXK1-1REC4-37171-100-V circuit breaker is based on the thermal-magnetic mechanism. The circuit breaker is equipped with a thermal-magnetic trip unit that consists of a bimetallic element and a magnetic tripping device. The bimetallic element responds to overcurrents, thus providing overload protection, while the magnetic tripping device reacts to short-circuit currents and provides short-circuit protection. Under normal conditions, the circuit breaker will remain in the closed position, while in the event of an overload or short-circuit, the trip unit will react and the trip contacts will open, thus interrupting the circuit and providing protection. The circuit breaker also features a manual reset switch, which allows it to reset after the overload or short-circuit has been cleared.

Conclusion: The IELZXK1-1REC4-37171-100-V circuit breaker is suitable for use in many applications and provides both over-current protection and switching operations in single-phase or three-phase AC circuits. The working principle of the circuit breaker is based on the thermal-magnetic mechanism, thus providing both overload and short-circuit protection. The circuit breaker can be used in combination with contactors and relays for additional protection and applications.
