The S202-C6 is a 2-pole miniature circuit breaker rated 6 A with a C-curve trip characteristic, meaning it tolerates brief inrush currents 5–10× the rated current before tripping — typical for motor starters, contactor coils, and small transformer loads where the magnetic pickup needs to ride through the energization spike without nuisance tripping. Rated 277 VAC phase-to-neutral (480Y/277 V wye service), this breaker lands in a standard 120/277 V lighting panel or a 480/277 V distribution board where each pole protects one phase conductor. The 2-pole form factor means it simultaneously opens both lines — required for a 240 V split-phase load or a 277 V single-phase circuit where disconnecting both hot legs is code-mandated.
The compact 2-module width (36 mm) leaves room alongside other S200-series breakers, contactors, and terminal blocks in a crowded enclosure.
