LMLZXK1-1RLS4-32446-40-V Circuit Protection

Circuit Breakers

LMLZXK1-1RLS4-32446-40-V circuit breakers provide load or motor protection, or provide a disconnect switch mechanism in motor control applications. As current flow increases, these air circuit breakers initiate contact separation and break the circuit by interrupting the electrical connection. The circuit is then held in the open position by the magnetic force of the circuit breaker mechanism.

Circuit breakers are categorized by current rating, voltage rating, interrupting capacity, operating temperature, construction type, and special features. Current ratings for circuit breakers range from 0.1 A to 6000 A, and their voltage ratings range from 1V – 690V. When selecting a circuit breaker, important parameters to consider include the maximum load current, interruption current, bimetallic element, and response time.

The LMLZXK1-1RLS4-32446-40-V circuit breaker is designed to open and close electrical circuits of low voltage systems, protecting personnel and assets from electric shock or equipment failure. It has an operating temperature range of -20 to +50 Celsius and a range of current and voltage ratings. It is designed with a bimetallic element that helps detect any increase or decrease in current and activates the opening or closing device. The response time is instantaneous, only taking a few milliseconds to react to changes in current.

The working principle of this circuit breaker is based on the electromagnetic and thermal effects. When the current flowing through the circuit breaker reaches its rated trip level, an electromagnetic force is generated and an arc is created between the contacts. This causes a build up of heat that pushes the contacts apart and opens the circuit. The bimetallic element within the circuit breaker reacts to any changes in temperature, and will automatic reset the device when the temperature returns to normal levels.

The LMLZXK1-1RLS4-32446-40-V circuit breaker is suitable for domestic, commercial as well as industrial purposes. It can be used in industrial wiring, portable equipment applications, motor-control panels, and motor-generator sets. It is also suitable for use with devices such as residential electrical panels, uninterruptible power supplies, and portable generators.

In conclusion, the LMLZXK1-1RLS4-32446-40-V circuit breaker is a highly versatile solution for protecting personnel and assets from electric shock or equipment failure. It has a wide range of current and voltage ratings, and is suitable for a variety of applications. It works by engaging an electromagnetic force that separates the contacts when current reaches dangerous levels, as well as a bimetallic element that will reset the device when temperatures return to normal levels.
