The ABB S202-D16 is a 2-pole miniature circuit breaker rated 16 A with a D trip curve, designed for DIN-rail installation in distribution panels and control cabinets.
Rated for 277 VAC phase-to-neutral (480Y/277 VAC system) with a 6 kA interrupting capacity, this breaker coordinates with downstream branch protection in typical North American commercial and light industrial panels. The 2-pole configuration provides simultaneous disconnection of both phase conductors, required for 240 V split-phase or 277/480 V line-to-neutral circuits where the neutral is not switched.
