The SKT2-100A 4P is a molded case circuit breaker (MCCB) for main and sub-feed distribution duties. Rated 100A frame, 4-pole, it interrupts all three phases and neutral together with a single operating handle, giving clear OFF-state isolation on 3-phase+N systems at 400VAC.
Inside the sealed thermoset housing, a thermal trip element responds to sustained overload while an electromagnetic element gives fast short-circuit protection — typically 5–10×In magnetic pickup. The unit mounts with screw terminals (or optional DIN-rail adapter), accepts large cross-section conductors, and suits main breakers, subpanel feeds, workshop disconnects, small HVAC and pump panels, and light-commercial distribution boards.
