Circuit Breakers: IEG66-27519-1-V

Circuit breakers are devices used to protect electrical systems from damage caused by overloads, short circuits and ground faults. The IEG66-27519-1-V is a type of circuit breaker designed to protect circuits against long duration overcurrents, arcing faults, and excessive operating temperature. This breaker utilizes both a thermal and magnetic trip element to achieve optimal performance.

Application Field

The IEG66-27519-1-V is a three-pole miniature circuit breaker, suitable for use in normal AC and DC circuits up to a rated voltage of 440V. The breaker has a rated current of 80A and a rated short-circuit capacity of 10,000A. It is designed for applications where protection and safety are essential, such as in industrial power distribution, machine control systems and HVAC equipment. The breaker is also suitable for use in photovoltaic and wind energy systems for enhanced protection.

Working Principle

The working principle of the IEG66-27519-1-V is based on the combination of a thermal and magnetic trip element. The bimetal thermal element senses the ambient temperature, and at higher temperatures it will expand to force the circuit breaker trip lever to its OFF position. The magnetic trip element detects high currents flowing in the system and at a certain point it will trip the breaker by moving a plunger to push the breaker trip lever to its OFF position.The integrated design of this breaker ensures that it can detect both high temperature and high current conditions and respond quickly to trip the breaker. The breaker also has adjustable current ratings and is UL489 listed, allowing it to be used in applications where safety is critical.

Compatibility

The IEG66-27519-1-V is a snap-in style breaker, and is compatible with most standard industrial control panels. It is encased in a white plastic housing for easy installation and the contractor is protected from accidental human contact during installation. The breaker is rated for environmental temperatures ranging from -25°C to 70°C and can operate in up to 95% relative humidity. Additionally, the breaker is designed to operate in noisy electrical environments and can withstand vibration up to 5 Hz.

Conclusion

The IEG66-27519-1-V is a versatile and reliable circuit breaker designed for industrial control applications. It utilizes a combination of thermal and magnetic trip elements to ensure optimal protection of circuits against high temperature and current conditions. The breaker is compatible with most standard industrial control panels, and is UL489 listed for maximum safety.
