    2 pole Miniature Circuit Breaker Details

    Tips: Difference between the circuit breaker and air switch
    1. Voltage level
    As to the low-voltage apparatus, the air switch is equivalent to the circuit breaker. As to the apparatus with the voltage grade below 500V, when there is a short circuit, the current can be cut off. In the high-voltage apparatus, the two are different. The circuit breaker can operate normally in various voltages above 220V. Its sustained load and short-circuit current are higher. However, the air switch will be cut off automatically if the current exceeds a certain value.
    2. Arc extinguish means
    The air switch extinguishes the arc with air as the medium. Therefore, it is also named as the air-type low-voltage circuit breaker. Because it has convenient operation and high safety, it is widely used. The circuit breaker has many arc extinguish means. So, its arc extinguish capacity is strong. The high-voltage apparatus usually employs the vacuum, sulfur hexafluoride for arc extinguishing.
    3. The effects
    The air switch usually plays a role of “isolation” and “protective equipment” in the small-current circuit. In the condition of short-circuit current and high current, the circuit breaker trips automatically. In the high-voltage and high-current circuit, it is normally used as the operating apparatus of powering off, powering on, connecting and disconnecting the load.

    Existing reviews of 32 amp 2 pole Miniature Circuit Breaker
    Great circuit breaker.
    Bought this circuit breaker for replacing the old one. I installed this breaker once receiving it. I am really happy that it solved the inrush current problem. Great product.
