That's the standard choice for resistive loads and general-purpose branch circuits where inrush is low (lighting, heaters, control transformers). For motor or drive feeds with higher inrush, a Curve C or D would be a better fit; this one's designed to hold through the brief surge of a resistive load, not a motor start. ## DC rating and panel integration The 500 VDC rating with 10 kA interrupting capacity is notable — many 2-pole MCBs in this footprint top out at 125 VDC. That makes the S202MUC-B13 usable in DC sub-distribution boards, solar combiner boxes, or battery-bank branch protection where the string voltage exceeds 250 VDC. On the AC side, 277 VAC matches the line-to-neutral voltage of a 480Y/277 V wye system, so it slots into commercial lighting panels or PDU tap-offs. Mounts on standard DIN rail; the S200MUC family uses the same busbar and accessory footprint as the broader S200 range.","metaTitle":"ABB S202MUC-B13 S200MUC MCB 2P B 13A DIN Rail","metaDescription":"ABB S202MUC-B13 S200MUC miniature circuit breaker, 2-pole, Trip Curve B, 13 A, 277 VAC / 500 VDC, 6 kA interrupting capacity.

We source the part through independent distribution and confirm both price and availability at quote time."},{"question":"What is the closest functional second-source to S202MUC-B13?","answer":"The ABB S202M-B10 is a close functional peer — same 2-pole DIN-rail footprint, same Trip Curve B, same 6 kA AC interrupting rating. Key differences: the S202M-B10 is rated 10 A (not 13 A) and its DC voltage rating is 125 VDC (not 500 VDC). It will drop into the same panel slot and busbar system without rewiring, but you must verify the ampacity and DC voltage requirements of the circuit."},{"question":"What compliance documentation does ABB provide for S202MUC-B13?","answer":"ABB typically provides a Declaration of Conformity covering the Low Voltage Directive and relevant harmonized standards (EN 60898-1 / IEC 60947-2). RoHS and REACH compliance statements are standard on the S200MUC series.
