A circuit breaker is an automatic electrical switch designed to protect and control an electrical circuit. Its main purpose is to detect electrical faults and trip the circuit in order to avert dangerous situations. This device is also designed to be able to reset the circuit after it has been tripped.

219-3-2600-525 Application Field and Working Principle

The 219-3-2600-525 circuit breaker is suitable for use in electrical networks of AC 50/60Hz with rated voltage being 3kV due to its own characteristics and rated working current of 25A. Its main component is a double-make and double-break electrical contact, with its contacts mounted in a single mechanism. Moreover, when there is an over-current, the thermal element within the mechanism is activated, causing the contacts to trip and break up the circuit.

In normal conditions, the circuit will remain closed with the switch contacts in an ON position. When a fault occurs, electric energy is converted into heat and then diffused within the device through the thermal element. This causes the working temperature to increase, breaking up the circuit via a mechanical trip device.

In addition, the 219-3-2600-525 circuit breaker is designed to enable resetting of the circuit after it has been tripped. On power up, the spring force of the springs pushes the switch contacts (tripped by heat) back to their ON position and closes the circuit.

The 219-3-2600-525 circuit breaker is designed with a manual control operating knob, so the breaker can be manually switched between "ON" and "OFF" position. It is also equipped with a trip-free mechanism, so the breaker would not reset while the operating handle is in the OFF position.

The 219-3-2600-525 circuit breaker is a reliable and economical solution for preventing electrical shock, fire, and other related risks. It is a great choice for industries such as Manufacturing, Oil & Gas, and Electrical Power Distribution industries, as it provides effective and safe circuit control and protection.
