1E5UM

E5UM circuit breakers are modern circuit breakers designed to protect circuits from damage due to overloads, short circuits, and ground faults. They operate using electromagnetic forces designed to trip and shut off power should a potentially hazardous situation occur. They are available in a range of sizes and ratings, making them incredibly versatile.

The working principle of the E5UM circuit breaker is quite simple. When an electrical current is passed through the breaker, a spring-loaded plunger is forced downwards. This compresses the electromagnetic force actuator, which increases the strength of the electromagnetic field. When an overcurrent, short circuit, or ground fault is detected, it causes an even larger increase in the strength of the electromagnetic field, which trips and releases the plunger, thus cutting off the electrical current to the circuit.

E5UM circuit breakers are traditionally used as the primary overcurrent protection device in electrical systems. However, they can also be used in combination with other circuit protection devices like surge protective devices and residual current devices, to provide a comprehensive solution for circuit protection. In addition, they are also suitable for a range of other applications such as motor control, emergency backup systems, and special loads.

E5UM circuit breakers are extremely reliable and efficient, making them a great choice for circuit protection. They are available in a range of sizes and ratings, making them highly adaptable for a variety of applications. They are also easy to install and maintain, making them a cost-effective solution for circuit protection.
