The 16 A rating and Trip Curve B define exactly what loads this breaker protects. Curve B trips magnetically between 3× and 5× rated current (48 A to 80 A), making it the right choice for resistive or lightly inductive circuits — lighting, socket outlets, small control transformers — where inrush is low. A Curve C or D breaker would be needed for motor or transformer primary protection, where starting current can hit 8–10× full load. The 2-pole configuration (DP) switches both line and neutral, so it suits single-phase 240 V split-phase or 277/480 V line-to-neutral circuits where the neutral must be switched alongside the hot leg. The 10 kA interrupting rating at 277 VAC is the standard breaking capacity for this class of MCB (EN 60898-1). If your installation has a higher fault level (e.g., near a large transformer), you would need a higher-rated MCB or a current-limiting upstream device.","metaTitle":"ABB S202P-B16 MCB 2P B 16A 277VAC, 10 kA","metaDescription":"ABB S202P-B16 miniature circuit breaker, 2-pole, 16 A, Trip Curve B, 277 VAC, 10 kA interrupting rating.
