Circuit breakers are important components of electrical engineering. 4120-G217-J1M1-M6S5ZN-3A is one of the commonly used circuit breakers. This article will focus on its application field and working principle.

Application Field:

4120-G217-J1M1-M6S5ZN-3A is designed for industrial application, specifically for the power distribution systems of most factories, plants, and production lines. It is mainly used in applications with load currents ranging from 20A to 125A with a rated voltage of 690V AC. The breaker is thermally stable and its contact system ensures reliable interruption of short circuit currents up to 10kA according to IEC60898.

Working Principle:

As an electrical component, 4120-G217-J1M1-M6S5ZN-3A has two main functions: protection and control. It protects the equipment from high currents caused by short circuits, as well as controlling the distribution of power. When properly installed, the breaker will detect the increase in current flow and open the circuit, thus preventing the equipment from further damage.

In general, the circuit breaker consists of two main components: an arc chute and a trip unit. The arc chute is a tube-shaped device which houses the electrical contacts that create the breaker’s circuit, while the trip unit is composed of an electromagnet that measures the current and controls the trip time. When a current overload occurs, the trip unit senses it and activates the electromagnet, which causes the breaker to open and disconnect the circuit.

When the current overload decreases, the trip unit detects it and deactivates the electromagnet, thus allowing the breaker to reset and re-establish the connection. Additionally, 4120-G217-J1M1-M6S5ZN-3A has over-temperature protection, which prevents it from tripping when exposed to high temperatures.

Conclusion:

4120-G217-J1M1-M6S5ZN-3A is a high-performance circuit breaker specifically designed for industrial applications. Its application field covers most factories, plants, and production lines. It is thermally stable and its contact system can handle short circuit currents up to 10kA. Its working principle relies on the arc chute and trip unit components, which establish the connections and detect when excessive currents appear, opening the circuit to protect the equipment.
