Circuit Breakers

A circuit breaker is an electrical device that is used for the protection of electrical circuits in a house or in larger industrial applications. The IELBXK111-34918-22 Trip Unit is a circuit breaker that is designed for industrial applications. It has the ability to detect faults on a network, trip and open the circuit to protect it from short circuit or overload conditions.

This device provides high levels of protection for circuits by detecting and clearing short circuit current as well as overloads. It is suitable for a wide variety of industrial applications including power plants, industrial motors, circuit protection systems, metal-clad switchgear, motor control centres and transformers.

The main components of the IELBXK111-34918-22 trip unit are the unit itself, an enclosure, a tripping coil, a contact, a contact arm, a trip time delay mechanism, and a self-protection feature. The device is activated by a switch or contactor, which opens or closes the circuit breaker. The trip time delay mechanism allows the circuit breaker to stay open until a preset current level is exceeded.

The self-protection feature of the IELBXK111-34918-22 trip unit helps to ensure that the device does not trip in the event of a power surge. This feature helps protect the system from short circuits, overloads and overvoltage conditions. It also helps reduce downtime and improve system reliability.

The IELBXK111-34918-22 trip unit has a maximum operation voltage of 600 volts AC, and a current rating of up to 300 amps. It is designed to be used with a three-phase power system. The device is UL certified and is suitable for a wide variety of industrial applications. In addition, it is designed for use in a harsh environment, withstanding extreme temperatures, dust, and moisture.

The working principle of the IELBXK111-34918-22 trip unit is based on the principle of a fuse. When the current through the contacts exceeds the preset level, a small copper wire inside the device melts, isolating the contacts from the circuit, and thus switching it off.

The IELBXK111-34918-22 trip unit is a reliable device that provides reliable protection for a wide variety of industrial applications. It is designed to be used in a harsh environment, withstand extreme temperatures and dust, and is UL certified. In addition, the device has a self-protection feature that helps prevent accidental tripping in the event of a power surge. This device provides a high level of protection for industrial circuits and is an ideal choice for applications where reliable trip protection is required.
