The Siemens SENTRON 5SL6105-7RC is a 1-pole miniature circuit breaker (MCB) rated 0.5 A with a C tripping characteristic and a 7.5 kA breaking capacity per EN 60898.
The C characteristic means the MCB trips magnetically at 5–10× rated current (2.5–5 A for this 0.5 A unit), so it handles moderate inrush from small inductive loads like contactor coils or control transformers without nuisance tripping. The 7.5 kA breaking capacity per EN 60898 certifies it can safely interrupt a fault current up to 7.5 kA at 415 V AC — adequate for most residential and light commercial service entrances where the prospective short-circuit current stays below that threshold. Single-pole design (1P) protects one phase; the neutral is not switched. The 0.5 A rating suits very low-current circuits — think signal supplies, pilot lights, or small control transformers — where a higher-rated breaker would not clear a fault before the wire or device overheats.
Installs in any orientation. Sealable with a lead seal for tamper-proofing in metered or security-conscious installations.
