Circuit breakers are an integral part of modern electrical infrastructure. They are designed to prevent an electrical circuit from becoming overloaded and causing permanent damage or a fire. The LELK1-1REC4-33274-2-V is a type of circuit breaker designed for the high-capacity needs of industrial and commercial applications. This article will explain the application field and working principle of the LELK1-1REC4-33274-2-V.

Application Field

The LELK1-1REC4-33274-2-V is a high-capacity circuit breaker with a voltage rating of 3,000 VAC and an overcurrent rating of 250A. It is suitable for use in a wide variety of applications, including industrial equipment and motors, commercial power distribution systems, high-voltage DC circuits, and power transformers. It is also suitable for use as a supplementary protection circuit, where it provides additional protection in case of a short circuit.

The LELK1-1REC4-33274-2-V is designed for use in hazardous locations, where it offers protection against explosions, fires, and other hazards. It is UL-Listed for use in Class I Divisions 1, 2, 3, and 4 hazardous locations.

Working Principle

The working principle of the LELK1-1REC4-33274-2-V is based on an electromagnetic field. When an overcurrent or fault is detected in the circuit, this field induces a magnetic field in the device. This magnetic field in turn causes the contacts in the circuit breaker to open, thus preventing the fault from continuing and potentially damaging the circuit.

The device is designed such that only when an overcurrent is detected will the contacts be opened. This ensures that the device is only activated when necessary, reducing the risk of damage to the electrical system. Furthermore, the device is designed to reset automatically after the fault has been cleared. This reduces the time and effort required to restore power to the system.

The LELK1-1REC4-33274-2-V is designed for prolonged and uninterrupted service. The device features built-in resistor-capacitor (RC) network which provides surge protection, ensuring that the device is not damaged by the high voltages typically found in the electrical system.

The device also features an anti-surge function which prevents a false triggering of the device in the event of a power surge. This ensures that the device does not activate unnecessarily, which reduces the risk of damage to the electrical system.

Conclusion

The LELK1-1REC4-33274-2-V is a high-capacity circuit breaker designed for use in industrial and commercial applications. It is UL-Listed for use in hazardous locations and offers surge protection and anti-surge functions for enhanced protection. The device features a working principle based on an electromagnetic field, which causes the contacts in the device to open when an overcurrent or fault is detected. This ensures that the device does not activate unnecessarily, providing enhanced safety and reliability for the electrical system.
