LMLHK11-1RLS4-39091-30-V Circuit Protection

A circuit breaker is an important device for the electrical infrastructure of homes and buildings. It is designed to trip and open the circuit in the event of a fault or overload. The LMLHK11-1RLS4-39091-30-V is a specific type of circuit breaker used to protect against damage from overcurrent, overload, and short circuit. It has a wide range of applications across many industries like power and electronics. This article will discuss the application field and working principle of the LMLHK11-1RLS4-39091-30-V.

Application Field

The LMLHK11-1RLS4-39091-30-V circuit breaker is primarily used in residential and commercial settings to provide overcurrent and short circuit protection. It can be used as a service-entrance breaker in single-phase residential applications, such as main disconnects for homes. It can also be used in industrial settings as a main disconnect, motor starter, or branch circuit protection breaker. The breaker is also suitable for use in Class A industrial applications with a current rating up to 20A and a voltage rating of 277VAC.

Working Principle

The LMLHK11-1RLS4-39091-30-V circuit breaker works by constantly monitoring the current flow in the circuit. If the current exceeds the rated current value, the circuit breaker will trip, interrupting the circuit and preventing damage to the appliance, wiring, or load. The breaker is triggered by a thermal overload or contact-force mechanism and consists of two parts: the trip unit and the contact point. The thermal overload mechanism uses an embedded bimetallic strip that bends when the circuit experiences an overload. This bend triggers the trip unit, causing the contact points to open and interrupting the circuit.

Conclusion

The LMLHK11-1RLS4-39091-30-V circuit breaker is a versatile and reliable device for protecting against overcurrent, overload, and short circuit. It is used in many different residential and industrial applications, offering reliable protection and minimal downtime. The circuit breaker typically uses a thermal overload or contact-force mechanism to open the contacts and interrupt the circuit. With its wide range of applications and reliable safety features, the LMLHK11-1RLS4-39091-30-V is an excellent choice for circuit protection.
