Circuit Breakers

A circuit breaker is a device that is designed to protect an electric circuit from damage caused by overload or short circuit. Circuit breakers may also provide switching of a circuit, in which case they are referred to as switchgear.

229-3-29540-17 Application Field and Working Principle

The 229-3-29540-17 Circuit Breaker is used for applications up to 690 VAC and protects circuits from short cirucits and ground faults. This circuit breaker can be used in residential, commercial, and industrial applications, including circuit connections for motor loads, lighting loads, heating and air conditioning equipment, machine tool equipment, and other non-continuous loads. It is typically used for the protection of load wires in electric power distribution circuits from failures caused by overload and short circuits.

The 229-3-29540-17 Circuit Breaker\'s working principle is based on the thermal overload protection principle. This device contains a bimetallic strip that will respond to heat generated by an overload current. When the current passes through the bimetallic strip, it will deflect in response to the heat, and open the circuit by tripping the breaker. This provides effective protection against overloads, ensuring the safety of the electrical circuit.

In addition to thermal overload protection, the 229-3-29540-17 Circuit Breaker also provides protection against ground faults. This circuit breaker includes a ground fault protection system which monitors the current in the circuit, and will trip the breaker if it detects a ground fault. The ground fault protection system includes an internal microprocessor to detect the presence of a ground fault, and will activate the circuit breaker as soon as a ground fault is detected. This ensures an effective protection against ground faults, ensuring the safety of the electrical circuit.

The 229-3-29540-17 Circuit Breaker also provides a reset function. This feature allows the circuit breaker to be reset after a fault or overload has occurred, allowing the circuit to be restored to operating condition. This reset feature helps reduce downtime, by allowing the circuit to be quickly restored to a safe operating condition.

The 229-3-29540-17 Circuit Breaker is a reliable and safe device that can be used for applications up to 690 VAC. This circuit breaker provides effective protection against overloads and ground faults, while also providing a reset feature for quick restoration of the circuit. This makes it an ideal choice for protecting electrical circuits from damage from short circuits and ground faults.
