Circuit Breakers

Circuit breakers are electrical switch devices designed to protect electrical systems from damage caused by overload or short circuits. They are a critical item in all industrial, commercial, and residential electrical systems. Often used in conjunction with a backup system or to provide emergency shutoff, circuit breakers are essential in providing safety and protection from electrical shock and fire risks. The LELZXK1-34921-1-V circuit breaker is an example of such a device.

Application Field

The LELZXK1-34921-1-V circuit breaker is a three-phase, four-pole device rated for 600 volts, and is suitable for most environments. It is designed to handle up to 65 kiloamps of alternating current and up to 40 kiloamps of direct current. It is a Type 3,Time Delay circuit breaker that has a trip level of 675-3450 mA. Applications for the LELZXK1-34921-1-V circuit breaker include control and power distribution systems, over-current protection of AC and DC voltage, industrial automation and variables, wind and solar energy systems, UPS systems, surge suppression and transient protection, as well as power supplies.

Working Principle

The operating principle of the LELZXK1-34921-1-V circuit breaker is based on a magnet that aligns the poles of the breaker around the current, creating a path to the main circuit. The main circuit includes a pair of contacts that can be either open (turning off the circuit) or closed (allowing electricity to flow) depending on the current that is present. When too much current is present, the pole will become magnetically charged and break the circuit, which in turn, trips the breaker and opens the contacts. Once the breaker is tripped, the contacts must be manually reset before the circuit can be closed again.

The LELZXK1-34921-1-V circuit breaker also includes several other features for controlling the circuit current. The breaker includes a trip-level selector which allows the user to choose between a fixed or adjustable trip level. It also includes an overload delay time selector which allows the user to specify how long the breaker will wait before it trips. The breaker also features an auto reset and a manual reset, which allows the user to reset the breaker without having to manually open and close the contacts.

With the LELZXK1-34921-1-V circuit breaker, safety and reliability are assured in electrical systems. This device helps to protect equipment and personnel, reduce downtime, and maximize the efficiency of electrical systems. The device is designed with a sleek, compact design which also allows for easy installation in tight spaces.
