The LW55-363 SF6 circuit breaker features a single-cut-mouth pressurized gas extinguishing chamber design, with a breaking current of 63kA and a rated current of 5000A. Conventional or dual-main, dual-standby intelligent heating tapes can be configured according to requirements. Equipped with disc spring hydraulic mechanism, high operational reliability, mechanical lifespan reaches 10,000 cycles. Phase-separated operation and three-phase electrical linkage operation. The basic design of current transformers uses windings with iron cores, which output secondary current through electromagnetic coupling. The coil is in an air environment, with the outer cover waterproof, sandproof, and protected against foreign matter entry.
