The Siemens SENTRON 5SL4102-7CC is a 1-pole miniature circuit breaker with C-curve tripping characteristic, rated 2 A and a breaking capacity of 10 kA according to EN 60898 at 400 V AC.
At 2 A, this is a low-current branch protection, not a main feeder or motor circuit. Single-pole construction means it switches only the phase conductor; neutral is not switched. Rated for 250 V single-phase or 400 V three-phase (multi-phase operation at 440 V max). The 72 V DC maximum rating covers some DC control circuits, but this is primarily an AC-rated device. The 18 mm width (1 modular unit) and 76 mm depth fit standard Siemens SENTRON enclosures and most DIN-rail panels.
Deployment context
Sealable design allows lockout/tagout for maintenance isolation. Halogen-free and silicon-free construction suits environments with sensitive electronics or cleanroom requirements.
