The versatility of the circuit breaker makes it a good fit for a wide array of duties, such as emergency shutdowns, manual and automatic reset, overcurrent maintenance, and short-circuit protection. It also features adjustable trip settings, adjustable thermal elements, and adjustable trip curves, which makes it a great choice for complex applications with different tripping criteria.

Working Principle

The working principle of the LELZXK1-1REC4-51-20.0-AGT-B3-V circuit breaker is based on the current limiting principle. This means that when the current going through the device exceeds its rated value, the breaker trips, thus preventing any further damage due to the overcurrent. This is achieved through the device’s thermal elements, which heat up and activate the tripping mechanism when the current reaches or exceeds the device’s set point.

The circuit breaker is also equipped with an adjustable trip settings and adjustable trip curves to meet the needs of different applications. This makes the device suitable for a range of conditions, allowing it to be used in a variety of applications.

The LELZXK1-1REC4-51-20.0-AGT-B3-V circuit breaker is a reliable and efficient way to protect circuits from overcurrents and damage. It is also designed to be easy to install, and its adjustable features make it a suitable choice for a range of complex applications.
