4120-G214-J1M1-K5S5ZG-25A Circuit Protection

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. The 4120-G214-J1M1-K5S5ZG-25A is an example of such a device. It regulates the flow of electricity in the circuit, providing reliable short circuit protection while allowing full utilization of allowable current levels in normal conditions.

Types of Circuit Breakers

There are many types of circuit breakers, and the 4120-G214-J1M1-K5S5ZG-25A falls into the category of low voltage circuit breaker. Low voltage circuit breakers are used for protecting and controlling circuits that operate on 50 up to 1000 volts AC and DC. Beyond 1000 volts are considered medium and high voltage circuit breakers.

The 4120-G214-J1M1-K5S5ZG-25A is a type of circuit breaker known as a current limiter. This type of circuit breaker is used for protection against abnormal current conditions such as overcurrent and short circuit events. The unique feature of this breaker is its two-step protection. It operates a dual trip system meant to keep the original overcurrent protection in place even after the first tripping of the overcurrent.

How a Circuit Breaker Works

The 4120-G214-J1M1-K5S5ZG-25A uses a sensing device inside its framework, which is usually a bimetallic strip in contact with an adjustment wheel. The contact of the bimetallic strip with the adjustment wheel is connected to the circuit breaker’s rating. The increase in current causes the bimetallic strip to expand and separate itself from the adjustment wheel, which results in the tripping of the circuit. This initiates the opening of the circuit to avoid a possible destructive electrical surge resulting from overloading the circuit.

The 4120-G214-J1M1-K5S5ZG-25A is suitable for applications where instantaneous overcurrent protection or short circuit protection is desired. It is highly engineered for reliable operation that allows full utilization of nominal current levels.

Applications for the 4120-G214-J1M1-K5S5ZG-25A

Low voltage circuit breakers like the 4120-G214-J1M1-K5S5ZG-25A are commonly used on industrial distribution networks, providing protection for operating equipment, motors, and other downstream devices. It is also used in residential dwellings and consumer switchboards. The 4120-G214-J1M1-K5S5ZG-25A is specifically designed for those applications that require the protection of personnel, the local environment, and equipment from short circuits or other abnormal current conditions.

The 4120-G214-J1M1-K5S5ZG-25A has been tested and approved for use in North American, European, and international markets. It is an economical, high performance, cost-effective solution for circuit protection in homes, industrial facilities, and other electrical systems.

Conclusion

The 4120-G214-J1M1-K5S5ZG-25A is a low voltage circuit breaker designed for use in residential dwellings, industrial facilities, and other electrical systems. It provides short circuit protection while allowing full utilization of allowable current levels in normal operating conditions. This type of circuit breaker is tested and approved for use in North American, European, and international markets.
