Product Details

MCCB Highlights

Alloy contact with high silver content: the silver content can reach 95%

1. High silver content, high conductivity, thermal conductivity, arc resistance, electric wear resistance,

2. Preparation of dynamic and static contact material standards and reliable process guarantee, improving the electrical life of circuit breaker by 50%

One of the key advantages of RCCBs is their ability to provide enhanced protection against electric shock. They are particularly effective in detecting small leakage currents that may not be detected by traditional circuit breakers, thus significantly reducing the risk of electrical accidents.
