IELK1-38394-20-V Application Field and Working Principle

Circuit breakers are safety devices designed to prevent electric overloads from short-circuiting, melting wiring or otherwise causing significant damage and even fatal electrocution. IELK1-38394-20-V circuit breaker is a High Voltage Circuit Breaker (HVCB) used mainly in industrial and commercial applications. This article looks at the application field and working principle of the IELK1-38394-20-V circuit breaker.

Application Field

The IELK1-38394-20-V is a high voltage circuit breaker (HVCB) rated for use in high voltage applications ranging from 3.6kv to 38kv and up to 6300A in most systems. It is UL 1558 listed and CSA approved for North America. The design and testing of this breaker exceeds UL and CSA requirements for all current application fields from industrial equipment and commercial installations to oil, gas and other hazardous locations.

Working Principle

The IELK1-38394-20-V circuit breaker uses a unique moving contact to achieve high performance. Its operation is based on a double-break system, which allows great sensitivity and reliability in operation. First of all, the line voltage enters the breaker through the main contact and is connected to the contact system. When the line voltage exceeds the rated value, the moving contact is moved and made to break the main contact connection. This interrupts the power supplied to the circuit. Next, the pre-arc contact is opened to ensure safe and reliable operation of the circuit breaker. The pre-arc contact is released and the arcing current is reduced as the arc is extinguished, preventing further damage. Finally, the main contact is reset and reconnected so that power is restored to the circuit.

Conclusion

The IELK1-38394-20-V circuit breaker is an advanced, high voltage breaker designed for use in industrial and commercial applications. It features a unique contact system that provides great sensitivity and reliability in operation. The breaker operates in a double-break system, where the main and pre-arc contacts are opened and closed respectively to achieve high performance. The IELK1-38394-20-V circuit breakers are UL 1558 listed and CSA approved and can be used in a wide range of hazardous locations.
