Reliable and Durable Miniature Residual Current Circuit Breaker 63A

Usually, a dedicated leakage testing instrument can be used. When the residual current circuit breaker is in the closed state, simulate a leakage fault and observe whether the circuit breaker can trip within the specified time. You can also press the test button on the Molded Case Residual Current Circuit Breaker 4P to perform manual tests regularly to check whether the leakage protection function is effective. If the residual current circuit breaker fails to trip normally during the test, it in

The residual current circuit breaker is mainly used to detect leakage (current leakage) in the circuit and quickly cut off the power supply when leakage occurs to prevent electric shock accidents or electrical fires. It can also provide overload and short-circuit protection.

Depending on the order quantity, delivery can usually be completed within 12 days after receiving the deposit. We have an efficient production process and a complete supply chain system to ensure that we can provide customers with high-quality products on time.

1. When installing the 4P Leakage Miniature Circuit Breaker, it is necessary to follow the installation specifications, leaving at least 5mm of space on the left and right sides, and more than 10mm at the top and bottom to avoid excessive temperature rise due to poor heat dissipation. 2. The 4P Leakage Miniature Circuit Breaker can be installed side by side with other circuit breakers, but it is necessary to ensure good ventilation in the distribution box, especially in the high-temperature envi

1. The neutral wire terminal of the 4P Leakage Miniature Circuit Breaker is usually non-directional, but some models are marked with 'N', which needs to be connected to the neutral wire (must be connected, otherwise the leakage protection will fail). 2. Wiring sequence: The incoming end L1/L2/L3 is connected to the three-phase live wire, and N is connected to the neutral wire; the outgoing end is connected to the load correspondingly. It is strictly forbidden to reverse the live wire and neutral
