Circuit breakers are an important safety device designed to protect people, buildings and equipment from electrical overloads, as well as provide convenience and cost savings for reliable operation in times of maintenance and supply. The LELHPK11-1REC4-30559-150 is a self-contained AC power circuit breaker, specifically designed for use in residential, commercial, industrial and professional applications.

The LELHPK11-1REC4-30559-150 is a single-pole, 30A, 240Vac rated circuit breaker. It is designed with a mechanical trip unit and manual reset feature that will detect overcurrent, leakage current or ground fault and trip the breaker to protect the electrical system from damage. It also includes a self-test feature that allows for continuous monitoring of the breaker’s performance. The LELHPK11-1REC4-30559-150 circuit breaker can be used in either an AC or DC power distribution system.

The main components of the LELHPK11-1REC4-30559-150 circuit breaker include the main power contact, the trip unit, and the manual reset button. The main power contact is made up of a set of copper or aluminum contacts and a thermal fuse that allow current to flow through the circuit. The trip unit is an electromechnical device which, when a harmful overload is detected, causes the contacts to open and the breaker to trip, thus preventing damage to the circuit. The manual reset button allows the user to manually reset the breaker if needed.

The working principle of the LELHPK11-1REC4-30559-150 circuit breaker involves the detection of potentially hazardous overloads and ground faults. To detect an overload, the trip unit uses a current sensor to monitor the level of current passing through the circuit. When an overload is detected, the trip unit sends a signal to the main power contact to open the circuit, thus preventing damage. The manual reset button then allows the user to manually reset the breaker after the overload is cleared. To detect a ground fault, the trip unit uses a special-purpose conductor to sense the presence of a ground fault. When a ground fault is detected, the trip unit will again open the main power contact and trip the breaker.

The LELHPK11-1REC4-30559-150 circuit breaker is suitable for use in a variety of residential, commercial, industrial and professional applications. Its self-test feature allows for continuous monitoring of its performance, while its manual reset feature allows for manually resetting the breaker if necessary. This circuit breaker is also capable of detecting both overcurrent, ground fault and leakage current. And its convenient size makes installation quick and easy.
