Introduction

IELHK111-30798-1-V is a type of circuit breaker, which is used to switch on and off circuits automatically. Circuit breakers are essential in industries, offices and home electrical systems as they provide a connection and disconnection solution for electricity distribution and switches on and off circuits. The IELHK111-30798-1-V circuit breaker is a high quality, efficient, reliable and adjustable circuit breaker that can be used in various motor control applications.

Application Field

The IELHK111-30798-1-V circuit breaker is suitable for various motor control applications, such as lighting control, household appliances, ventilation equipment, door control systems, elevator controls, and so on. This breaker is designed for switching on and off electricity circuits quickly and safely. It is suitable for a wide range of current ratings, from 16~400A. The voltage range available for this breaker is 480VAC or above. It has adjustable tripping current setting. This breaker is UL and CE approved.

Working Principle

The IELHK111-30798-1-V circuit breaker has a three-pole construction layout which includes two main contacts and one auxiliary contact. Electrical power flows in through one main contact and out through the other main contact. The auxiliary contact is used to interrupt the power flow in case of any emergency. When the electric current flowing through the circuit exceeds the pre-set value, the internal components of the breaker will sense this and rapidly drop the contacts of the breaker, thereby shutting off the power to the circuit. This shuts off the power before the current value has a chance to damage the devices connected to the breaker. When the current value drops below the pre-set value, the contacts of the breaker will be automatically restored to the on position.

Conclusion

The IELHK111-30798-1-V is a reliable and efficient circuit breaker suitable for various motor control applications. It has adjustable tripping current setting which can be used to manage power flow within the circuit. This breaker is UL and CE approved and is suitable for a wide range of current ratings from 16 to 400A, and a voltage range of 480VAC or above. With its three-pole construction layout including two main contacts and one auxiliary contact, it performs efficiently in switching electricity circuits both on and off in case of emergencies.
