IELHR110-30776-4-V

Circuit Breakers are essential components in the electric current industry. The IELHR110-30776-4-V is just one type of this critical device. Let\'s take a closer look at the application field, and the working principle behind it.

Application Field

IELHR110-30776-4-V is primarily used for earth fault protection when it comes to single-phase, two-phase, and three-phase circuits. These circuits may include those running in Alternating Current (AC) or Direct Current (DC) systems. This type of circuit breaker can protect against various types of under-voltage, over-voltage, and over-current. When it comes to installation and application, IELHR110-30776-4-V are simple and cost-effective.

Working Principle

The IELHR110-30776-4-V is based on a simple mechanical principle. This circuit breaker utilizes a thermal-magnetic tripping system that uses a thermal bimetall element to detect and disconnect the flow of electricity. The thermal bimetall element is made out of two different alloys, which expand at different rates when heated. When there is an imbalance in the amount of current running through the circuit, the bimetall element will expand and trip the circuit breaker. As the current balance is restored, the bimetall element will return to its original size and the circuit breaker will reset.

Furthermore, the IELHR110-30776-4-V includes a built-in short circuit protection. This is done with the use of a magnetic module. When a short circuit occurs, the magnetic forces generated will cause the circuit breaker to trip and disconnect the circuit. This type of protection is important in preventing long term damage to electronic devices connected to the circuit.

Conclusion

The IELHR110-30776-4-V is an important and reliable circuit breaker with many useful features. Its usage and application field includes single-phase, two-phase, and three-phase circuits running with AC or DC systems. It utilizes a thermal-magnetic tripping system with a thermal bimetall element that expand to detect and disconnect the flow of electricity. Additionally, it includes a built-in short circuit protection, that trips the circuit to prevent damage to connected electronic devices.
