The Siemens SENTRON 5SL4502-7CC is a 1P+N miniature circuit breaker with a C-curve tripping characteristic, rated 2 A at 230 V AC. Its 10 kA breaking capacity per EN 60898 means it can safely interrupt fault currents up to that level in residential and infrastructure final circuits — enough for most domestic distribution boards and light commercial sub-panels. The C-curve (5–10× In) handles moderate inrush from small motor loads, lighting banks, and transformers without nuisance tripping.
Mounting and panel fit
Snaps onto standard DIN rail, occupies 2 width units (36 mm total). Installation depth is 70 mm; overall depth with terminals is 76 mm. Mounting position is unrestricted — install horizontally, vertically, or flat. The neutral pole is switched (1P+N), so this breaker disconnects both line and neutral on fault. Touch protection is built into the terminals. Rated for pollution degree 2 and overvoltage category III, which covers fixed-installation downstream of the main distribution board.
