Circuit Breakers

Circuit breakers are devices used to protect electrical systems, equipment and personnel from damage or failure due to overloads, short circuits and other faults. The IEGH66-1REC4-40878-1-V circuit breaker is a type of protective device that automatically opens an electrical circuit when it detects an overload or short-circuit.

Application Field

The IEGH66-1REC4-40878-1-V circuit breaker is designed for use in a variety of applications, including motor loads, industrial control circuits, lighting circuits and air conditioning systems. It is also suitable for applications in which there are large loads and a high demand for fault protection.

The IEGH66-1REC4-40878-1-V circuit breaker is designed to provide protection in environments with currents up to 30A and voltage up to 600VAC. It is also designed to provide protection against overheating, overcurrent, short circuit, lightning and other potentially damaging events.

Working Principle

The IEGH66-1REC4-40878-1-V circuit breaker utilizes a thermal-magnetic operating principle. When an electrical overload or short-circuit occurs, the circuit breaker is designed to open the circuit. This is accomplished by the internal mechanism of the circuit breaker which consists of two parts: a temperature impact bimetal and a magnetic shunt trip coil.

The temperature impact bimetal is responsible for sensing the temperature of the circuit breaker. When the temperature rises due to an overload or short circuit, it causes the bimetal to bend and releases a tripping current. This tripping current is then processed by the integrated circuit which signals the magnetic shunt trip coil to open the circuit. This mechanism provides fast and reliable protection against damaging overloads and short circuits.

The magnetic shunt trip coil part of the circuit breaker is made up of a magnet and solenoid coil. When the tripping current is sent, the solenoid coil is activated and magnetically attracts the movable contact of the circuit breaker. This causes the circuit to open, thereby interrupting the flow of current and protecting the circuit from further damage.

Conclusion

The IEGH66-1REC4-40878-1-V circuit breaker is a type of protective device designed to provide protection against potentially damaging overloads and short circuits. The device utilizes a thermal-magnetic operating principle to quickly and reliably interrupt power when an overload or short circuit is detected. It is suitable for a variety of applications, including motor loads, industrial control circuits, lighting circuits, and air conditioning systems. By understanding its application field and working principle, users can ensure that their IEGH66-1REC4-40878-1-V circuit breaker is used properly and that their equipment and personnel remain safe from potential damage.
