It occupies a single modular width (18 mm) on the DIN rail, so panel space is tight — one pole per 18 mm slot, no room to squeeze a second circuit into that width.
Rated breaking capacity is 7.5 kA per EN 60898 at 415 V AC, 50/60 Hz. That figure governs the upstream fault level it can safely interrupt — if your panel's prospective short-circuit current exceeds 7.5 kA, this breaker needs a current-limiting upstream device or you step to a higher-rated frame. The single-pole rating at 250 V AC covers line-to-neutral faults in single-phase circuits; multi-phase operation is rated at 440 V AC maximum.
Environmental range and mounting
Mounting position is unrestricted — vertical, horizontal, upside-down; the thermal-magnetic mechanism doesn't care about orientation. IP20 with connected conductors means the busbar stabs are live when the breaker is snapped in; the front terminals are touch-safe only after wiring. Sealable, halogen-free, silicon-free — relevant for clean-room or harsh-environment specs where outgassing matters.
Lifecycle status is active — this is a current-production catalog item from the SENTRON 5SL series. For a BOM freeze, this part is stable — no imminent PCN risk.
