Circuit breakers are the most widely used safety devices in the electrical industry, used to protect the electrical system from overload and short-circuiting. Nowadays, with the development of industry, 1G2.5UM-type circuit breakers have become increasingly popular.

The 1G2.5UM circuit breaker is a kind of miniature circuit breaker with double pole, suitable for AC 50/60 Hz, rated operating voltage of up to 400V and rated operating current up to 32A. It has overload protection, short-circuit protection, under-voltage protection and polarity reversal protection. The advantages of this type of circuit breaker are mainly in its small size and low cost.

The working principle of 1G2.5UM circuit breaker is divided into two parts: breaking and making. In breaking, when there is an overload, short-circuit or under-voltage current at a certain time, the circuit breaker will quickly sense it, and then rapidly cut off the circuit to protect the equipment. The point is that when the current reaches the trip current, it can quickly cut off the circuit. In making, after the circuit breaker’s over load, short-circuit or under-voltage is eliminated and the circuit breaker recovers its sensitive reaction, it can then automatically close the circuit.

In terms of application fields, the 1G2.5UM circuit breaker is mainly used in household circuits, three-phase AC power distribution systems, lighting circuits, motors and power distribution systems in buildings, factories and so on. In addition, it can also be used as a protection device to cut off the overload, short-circuit and under-voltage current to protect the equipment.

In summary, the 1G2.5UM circuit breaker is a miniature circuit breaker with double pole, suitable for AC 50/60 Hz, rated operating voltage of up to 400V and rated operating current up to 32A. It has overload protection, short-circuit protection, under-voltage protection and polarity reversal protection. It is mainly used in household circuits, three-phase AC power distribution systems, lighting circuits, motors and power distribution systems in buildings, factories and so on. It is not only economical and reliable, but also has a fast reaction speed, which can keep people and electrical equipment safe, and reduce the loss of electrical equipment.
