Circuit Breakers

Circuit breakers are a vital piece of technology used to protect electrical systems from damage due to shorts or overloads. One such device is the CB187P-35, a popular and reliable circuit breaker used in many contexts. In this article, we’ll explore the CB187P-35’s application fields and its working principle.

Application Fields

The CB187P-35 is a reliable two-pole breaker ideal for protecting residential, commercial and industrial covering all common circuits from 15-100 amps. It provides protection up to 480 volts AC and is available in a wide variety of configurations. It is easy to install and helps extend the life of other electrical components.

Working Principle

The CB187P-35 works by using a trip switch to interrupt the circuit when an abnormally high current or overload is detected. The time delay of the trip mechanism is designed to prevent nuisance tripping, while the high interrupting capacity ensures the CB187P-35 can handle most short-circuit and overload conditions.The trip switch is opened by a trip unit, which is connected to a heat sensitive bi-metallic element. When the current exceeds a predetermined value, the bi-metallic element bends and triggers the trip unit, which releases the trip switch, stopping the current flow. To reset the breaker, the switch takes a turn to its normal position.

Conclusion

The CB187P-35 is a reliable and effective circuit breaker suitable for residential, commercial and industrial use. It is easy to install and offers protection up to 480 volts AC against shorts and overloads. The CB187P-35’s trip mechanism works by using a heat sensitive bi-metallic element and a trip switch to open the circuit and prevent damage.
