At 277 VAC line-to-neutral (480Y/277 V wye systems), it handles the full phase-to-neutral voltage common in North American commercial panels. In a panel with an upstream main breaker rated higher than 6 kA available fault current, you need a current-limiting device ahead of it or a higher-rated downstream breaker. DIN rail mounting means it snaps onto standard 35 mm top-hat rail. The 2-pole width occupies two modular spaces (36 mm) — plan your enclosure fill factor accordingly.

Frequently asked questions
What is S202-C3's listed amps and type?
It is a 3 A, Trip Curve C miniature circuit breaker — the C curve provides magnetic trip between 5× and 10× rated current, suited for moderate inrush loads.
Will S202-C3 drop into a panel specified around S201M-C3 without rewiring?
No — the S201M-C3 is a single-pole breaker; the S202-C3 is a 2-pole unit. They share the same DIN rail footprint and Trip Curve C, but the pole count difference means the S202-C3 occupies two modular spaces instead of one and requires a 2-pole feed.
Where can I buy S202-C3 and how is it quoted?
The S202-C3 is sourced to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial offer.
