Circuit Breakers: IELHR11-0-SW-50.0-C-11 Application Field and Working Principle

Circuit breakers are electrical components that protect a piece of electrical equipment from being overwhelmed by electrical current. The IELHR11-0-SW-50.0-C-11 is a type of circuit breaker designed for residential and commercial applications, such as in an electrical panel for a home and commercial buildings. This article will discuss the application field and working principle of the IELHR11-0-SW-50.0-C-11.

Application Field

The IELHR11-0-SW-50.0-C-11 is designed for use in residential or commercial panels. It is suited for applications such as lighting, appliances, air conditioning, heating, or any other electrical equipment where overloads may occur. Due to its small size, it is also suitable for tight spaces, such as for circuit breakers in an outdoor panelboard or for back-fed load center panels.

Working Principle

The IELHR11-0-SW-50.0-C-11 is an overload breakers with a trip level of 50.0 amps. It is designed with a thermal-magnetic operating principal. Under normal operating conditions, when the current stays below 50.0 amps, the switch will remain closed and allow electrical power to pass through. When the current exceed 50.0 amps, the thermal-magnetic sensing element of the device will activate, sending an electrical signal to the contactors that open the switch. This will cause an interruption of power supply and a corresponding increase in temperature, which will trigger the magnetic force of the device and cause it to open the circuit. When the current passes the trip level of 50.0 amps for a sustained period of time, the device will reset itself and be ready to detect a possible malfunction again. This is determined by the ability of the device to cool down to a temperature lower than 60 Celsius, at which point the magnetic force of the device has recovered and the circuit can be re-energized.

Conclusion

The IELHR11-0-SW-50.0-C-11 is an overload breakers designed for residential or commercial applications, where it can detect any overloads and trip the circuit breaker before the current passing becomes hazardous. It can easily be integrated into any existing electrical panel, as it is a compact and reliable device. It is designed with a thermal-magnetic operating principal, which can detect the excess current and cool down to reset itself.
