MCCB遮断器 WLM6シリーズ産業用サーマル磁気タイプ遮断器 400V/690V 250A 3/4極
Rated Current : 250A Number Of Poles : 3P / 4P Rated Working Voltage : 400V/690V
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.
