The 50 A rating and D curve are the key fit decisions here. Two poles cover a single-phase 277 VAC line or a 480Y/277 VAC line-to-neutral circuit. The DIN-rail footprint drops straight into any standard panel enclosure.
The IP20 enclosure rating (IP40 with cover) suits dry indoor panel environments; no washdown or outdoor sealing is built in.
It's rated 50 A with a Trip Curve D characteristic (magnetic trip between 500–1000 A, thermal trip at 62.5 A).
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Both share the same 2-pole DIN-rail footprint, so mechanical fit is the same. The difference is trip curve — the S202-D50 uses a D curve for high-inrush loads, while the S202M-C63 uses a C curve and is rated 63 A. Rewiring is not needed, but the trip characteristic and amp rating must match the circuit design.
