The 10 A continuous rating sets the thermal threshold for overload protection. The D-curve means the magnetic instantaneous trip is calibrated to activate between 10x and 20x In (100–200 A), so it will not nuisance-trip on high inrush currents from small motors, solenoid valves, or transformers. The 2-pole configuration switches both line and load conductors, which is typical for single-phase 240 V or split-phase 277 V circuits. ## Deployment context The S200 series uses a common busbar system and accepts auxiliary contact, shunt trip, and undervoltage release accessories that clip onto the right side. For a panel OEM, the 2-pole width occupies two modular 17.5 mm spaces.","metaTitle":"S202-D10 Miniature Circuit Breaker, 10 A, D Curve, 2 Pole","metaDescription":"S202-D10 miniature circuit breaker, 10 A, Trip Curve D, 2-pole, 277 VAC, 6 kA interrupting rating.
