LELK1-1REC4-34927-20

Circuit breakers play a vital role in ensuring the safety, reliability, and convenience of electrical circuits. They are designed to detect faults and quickly shut off electrical current to protect the circuit from damage caused by overloads and short circuits. The LELK1-1REC4-34927-20 is a type of circuit breaker, which is used for higher-end applications and has a specific working principle.

The LELK1-1REC4-34927-20 circuit breaker is designed for switchgear applications that require high characteristics and long-term reliability. It is a three-pole, miniature circuit breaker for use in AC systems up to 1000 V, and up to 40 kA interrupting capacity. It is suitable for maintaining voltage, controlling short-circuits, and providing permanent over-current protection. It also features adjustable differential tripping, adjustable short circuit tripping, and adjustable overload tripping to better suit the needs of the switchgear.

The LELK1-1REC4-34927-20 circuit breaker is designed to detect a fault, or an overcurrent, in the circuit. It works by employing electromagnets and bimetallic strips to sense the current in the circuit. When the current in the circuit exceeds a certain limit, the bimetallic strips mechanically trigger the circuit breaker, which interrupts the flow of current to the circuit.

The LELK1-1REC4-34927-20 circuit breaker is typically used in applications such as pressure and environmental control systems, manufacturing industries, power plants, and electrical systems that require high performance. The device is also suitable for a wide range of other applications, including motor control, lighting, HVAC control, power supplies, and other industrial applications. In general, it can be used to protect circuits from short-circuits and overloads.

To ensure safe operation, the LELK1-1REC4-34927-20 circuit breaker is fitted with an indicator light, which indicates whether the breaker is On or Off. Additionally, the device has an adjustable thermal-magnetic tripping system, which can be set to a specific tripping level to safeguard the circuit against incorrect operation. Furthermore, the device is certified to meet the safety requirements of UL489, CSA C22.2 No. 5-04, and IEC60898-1 specifications.

In conclusion, the LELK1-1REC4-34927-20 circuit breaker is an advanced, high-performance device used for a wide range of applications. Its working principle is based on the use of electromagnets and bimetallic strips to detect overcurrents in the circuit and quickly shut off the current to protect the circuit from overloads and short-circuits. The device is also designed with safety features such as an indicator light and adjustable tripping system to further protect the circuit.
