IUG1111-1REC4-72-30.0-01

Circuit breakers are electrical devices that perform a variety of protective, controlling, and switching functions. The IUG1111-1REC4-72-30.0-01 circuit breaker is designed to meet the challenging requirements of industrial and residential applications. This breakdown introduces its application field and working principle.

Application Field

The IUG1111-1REC4-72-30.0-01 is a multi-function low voltage breaker. It is mainly suitable for the protection and control of circuit equipment in the three-phase AC 50/60Hz power system of rated voltage up to 660V and rated current up to 100A. It can provide short circuit and overload protection for motors, transformers, lighting and power equipment, and can also be used for centralized control of multiple remote terminals. During industry production and transformation, it can also be used as a switch for control circuit, measuring circuit and signal control circuit in accordance with relevant regulations.

Working Principle

When the IUG1111-1REC4-72-30.0-01 works normally, the power supply Entering the line is stopped by the circuit breaker. Under normal circumstances, the circuit breaker takes up a low resistance state similar to that of the wire. When an overload current or short circuit current passes through the line, the overload protection or short circuit protection of the circuit breaker is started after instantaneous insulation displacement. During the fault current flow, the insulation and moving contact of the circuit breaker are quickly separated, and the transmission circuit is disconnected. In case of overvoltage, the circuit breaker activates at the same time with the overvoltage detection device in the system to separate the circuit. After the head is opened, the circuit breaker moves quickly to the closing position and the tripping indicator is indicated.
