Miniature Isolating Switch 3P

The Miniature Isolating Switch Series is a type of manual electrical switching device applied in power distribution systems, whose primary function is to cut off the power supply during circuit inspection, maintenance or repair, forming a visible and distinct break point to ensure the personal safety of maintenance personnel. It generally does not have overload and short-circuit protection capabilities, and cannot be used to interrupt normal operating current, being only suitable for circuit breaking operations under no-load or light-load conditions. With a compact structure and modular design, it can be directly mounted on a standard 35mm guide rail, adapted to both single-phase and three-phase power distribution scenarios. Widely used in the distribution boxes of industrial plants, commercial buildings and residential dwellings, it is often used in conjunction with protective electrical devices such as micro circuit breaker (MCB) and residual current circuit breaker (RCCB), serving…
