The 5SQ2170-2YA15 is a 1-pole miniature circuit-breaker from the SENTRON 5SQ series, rated 1.6 A with a C tripping characteristic. It accepts AC or DC supply voltage, which matters when the same rail feeds both an AC distribution board and a DC control circuit — same part, different passport.
Single width unit (1 MW) on a DIN rail, installation depth 55 mm. No neutral switching (single-pole only), so the neutral bar stays continuous through the panel.
3 kA per EN 60898 at 240 V AC. That is the standard short-circuit rating for domestic and light-commercial final circuits.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
Mechanically yes — both share the same DIN-rail footprint, 55 mm depth, and IP20 form factor. The 5SQ2170-2YA15 is 1-pole (1 width unit) versus the 3-pole sibling, so it occupies one module position instead of three. No rewiring of the bus is needed for the pole that is present.
