ABB 2CSS255101R0165 SN201-B16 1P+N 16A B-Curve 6kA Miniature Circuit Breaker (MCB)

Rated 16 A with a type B tripping characteristic, the ABB SN201-B16 (SKU 2CSS255101R0165) is a single-module, 1P+N DIN-rail breaker with 6 kA breaking capacity at 230 V AC. It switches and protects the line conductor while passing the neutral through a fixed right-side terminal, and its 3-5× In instantaneous trip band suits resistive lighting and socket circuits with minimal inrush.

Selection Notes

At In 16 A, the SN201-B16 covers a step up from the lightest SN201 rating while keeping the same type B instantaneous trip band (3-5× In) and 6 kA breaking capacity at 230 V AC. It fits resistive and lightly inductive single-phase circuits such as general lighting or socket outlets; where a circuit has motor starting current or ballast inrush, a C or D curve device is the better fit, not a higher-current B-curve. The right-side neutral terminal keeps wiring orientation consistent with the rest of the SN201 range.
