Siemens 5SJ6505-7 SENTRON MCB — 1P+N, C-curve, 0.5 A
The Siemens 5SJ6505-7 is a SENTRON 5SJ6 series miniature circuit breaker with 1P+N poles, a C-curve tripping characteristic, and a rated current of 0.5 A at 240 V AC.
Rated 0.5 A at 240 V AC — this is a low-current branch circuit protector, sized for control transformers, signal circuits, or small lighting strings, not general-purpose power outlets. The C-curve holds through the inrush of a small contactor coil or a few LED drivers. The 6 kA breaking capacity (EN 60898) is standard for domestic sub-distribution; the same 6 kA under IEC 60947-2 confirms it for industrial panel use where the prospective short-circuit current stays under that threshold. 1P+N design switches line and disconnects neutral on trip. Occupies 2 width units on DIN rail. Maximum DC voltage is 60 V. Rated insulation voltage is 440 V AC. Multi-phase operation up to 440 V AC maximum.
Deployment context
Installation depth is 70 mm. IP20 with connected conductors. The sealable feature allows the breaker to be locked in the OFF position with a padlock for lockout/tagout procedures.
