On a 10 A frame, expect the magnetic trip to operate between 8× and 12× rated current (80–120 A instantaneous). That makes this breaker a natural fit for mixed inductive-resistive loads in a control panel — think a bank of contactor coils plus a small transformer primary. ## Panel integration Four-pole width occupies 72 mm (4 × 18 mm modular units).","metaTitle":"ABB S204-K10 MCB 4P K 10A 277V, DIN Rail","metaDescription":"ABB S204-K10 miniature circuit breaker, 4-pole, Trip Curve K, 10 A, 277 VAC, 10 kA interrupting capacity.

That means it can safely interrupt a fault current up to 10,000 A without external current-limiting fuses — sufficient for most commercial and light industrial panelboards where the available fault current is under that threshold."},{"question":"Can I use the S204-K10 to replace a 3-pole S203-D13 in a panel?","answer":"No — the S204-K10 is a 4-pole breaker with a K-curve magnetic trip, while the S203-D13 is a 3-pole D-curve unit. The pole count and trip characteristic differ, so a direct drop-in replacement would require rewiring the neutral/grounding scheme and verifying coordination with downstream loads. The S203-D13 is a different part for a different duty."},{"question":"Where can I buy the S204-K10 and how is it quoted?","answer":"The S204-K10 is sourced and quoted to order against an RFQ through independent distribution.
