1. Strong protection capability: With more contacts, small circuit breakers can provide stronger protection and isolation functions. When a circuit malfunctions, it can quickly cut off the faulty circuit and prevent the accident from expanding.

2. High reliability: The design of two contacts makes the circuit breaker more stable, reliable, and less prone to damage during operation. At the same time, multiple contact surfaces also improve the conductivity and contact reliability of the circuit breaker.

3. Low cost: Compared to traditional three-pole circuit breakers, the production cost of small circuit breakers is lower. This is mainly due to its simple structure, compact size, and the need for fewer materials. Therefore, for equipment that requires frequent replacement, using small circuit breakers may be an economical option.

4. Easy installation: Small circuit breakers are usually lighter and easier to transport and install than traditional circuit breakers. This allows them to be applied in various situations, including homes, commercial venues, and public facilities. In addition, small circuit breakers can also be embedded in walls or other surfaces without occupying additional space.

5.Easy maintenance: Small circuit breakers have relatively few contacts, making them easier to repair and maintain. Only a few components need to be inspected and replaced to restore normal operation or replace faulty components.
