A circuit breaker is a switching device designed to protect electrical circuits from damage caused by overload, or short-circuiting. 3131-AF1PT-000000-1Y2-7A is a kind of circuit breaker which is usually used to protect large electrical systems with high capabilities and large current flow.

Application Field

3131-AF1PT-000000-1Y2-7A is an ideal choice for use in large-scale electrical systems, such as power plants, oil and gas platforms, and even large ships due to its large operation capabilities. Not only can it protect large electrical systems from over-currents and short circuits, it is also designed to protect large systems from excessive voltage surges. This type of circuit breaker also offers reliable protection against over-voltage and under-voltage, making it ideal for use in industries and applications that require reliable protection against these conditions.

Working Principle

3131-AF1PT-000000-1Y2-7A circuit breaker operates on the principle of current sensing. When the current flowing through the system reaches a certain level, the breaker will trip and disconnect the circuit. This is achieved by using current sensors, which measure the current flowing through the circuit and compare it to a predetermined level. If the current level exceeds the predetermined level, the breaker trips and the circuit is disconnected.

In addition to current-sensing, this type of circuit breaker also features thermal protection. This protection is achieved through internal heating elements, which heat up when the circuit is carrying too much current. The internal heat sensors detect the increased temperature and trigger a thermal trip, automatically isolating the circuit.

The 3131-AF1PT-000000-1Y2-7A also incorporates overvoltage protection, which is triggered when the voltage in the circuit exceeds the maximum allowable level. This is usually achieved through a voltage sensitive relay, which disconnects the circuit if the voltage rises too high.

Lastly, the 3131-AF1PT-000000-1Y2-7A circuit breaker also features protection against ground fault protection. This is achieved through an internal resistor, which will trip if there is an imbalance between the Neutral and Ground wires. If the resistance becomes too high, the circuit breaker will trip and the circuit will be disconnected.

Conclusion

In summary, the 3131-AF1PT-000000-1Y2-7A is a high-quality circuit breaker designed for use in large-scale electrical applications. It features current sensing, thermal protection, overvoltage protection and ground fault protection, all of which combine to ensure a safe and reliable electrical system.
