- Description
The ABB 2CSS255101R0024 is a SN201-C2 miniature circuit breaker: a 1P+N, 2 A device with a C tripping curve and 6 kA short-circuit capacity at 230 V, sized for low-current control and signaling circuits. It fits one DIN-rail module, uses cage screw terminals, and places the neutral terminal on the right.

Selection Notes
The C tripping curve trips instantaneously between 5 and 10 times In, so this 2 A breaker tolerates the brief inrush of small control transformers or indicator-lamp circuits without nuisance tripping. Its 2 A rating is intended for lightly loaded control or auxiliary circuits, not general lighting or socket outlets; step up to a higher-current sibling in this series as soon as the connected load's steady-state draw nears 2 A.
