High Protection Power Distribution Board, Vacuum Circuit Breaker
Introduction - JM4 High Protection Power Distribution Board1. JM4-1(CI) Insulated Power Distribution Board adopts full-insulated modules and closed distribution system which can be applied to various power supply needs, especially in the harsh environment. E.g.: the chemical plants, packaging workshops, flour mills, cement plants as well as nuclear power stations and the subway tunnel.
2. CI Insulated Power Distribution Board is a protection rank IP65. Its shell is made of high- quality polycarbonate engineering plastic. This material is fully-insulated and corrosion-resistant as well. It also has high mechanical impact strength and will not aging. Its shell is transparent so it could inform the operator of the distribution state before break down or power failure.
3. JM4-1(CI) Insulated Power Distribution Board of our company has been approved by the National Compulsory Product Authentication.
Structure Features - Power Distribution Board
1. Full-insulated shell is one of the top security ranks and does not change with the time. Thus, it does not need maintenance. Besides, full-insulated is much safer than grounding.
2. closed bolt with a lid
