It snaps onto DIN rail — standard panel fit for lighting, motor, or distribution subfeeds where high inrush loads (transformers, small motors, power supplies) need the delayed magnetic trip of a D-curve to avoid nuisance trips on startup. The 2 A continuous rating governs the load it protects — sized for a circuit drawing up to 2 A steady. The D-curve means the magnetic trip is set to 10–20× rated current (20–40 A instant trip), so it tolerates the startup surge of a small transformer or contactor coil without dropping out. ## Panel integration Single-pole width (about 17.5 mm) — fits a standard distribution board or sub-panel. No special busbar or bridging required for single-pole use; if you need multi-pole ganging, the S200 series uses the same rail and accessory comb busbar.","metaTitle":"ABB S201P-D2 MCB 1P D 2A 277VAC, 10kA","metaDescription":"ABB S201P-D2 miniature circuit breaker, 1-pole, Trip Curve D, 2 A, 277 VAC, 10 kA interrupting.

The difference is the trip curve: D-curve (10–20× In) vs K-curve (8–14× In). If the panel was coordinated for K-curve magnetic trip thresholds, swapping to D-curve may shift selectivity boundaries — check the coordination study before substituting."},{"question":"Where can I buy S201P-D2 and what is the price?","answer":"Sourced to order against an RFQ through independent distribution.
