The Siemens 5SL6104-6 is a 1-pole SENTRON miniature circuit breaker rated 4 A with B-curve tripping characteristic, designed for 230/400 V AC residential and infrastructure branch circuits. Not intended for motor-starting duty; that calls for a C or D curve.
DIN-rail fit and panel integration
Mounting position any, so horizontal busbar layouts in compact consumer units are fine. Degree of pollution 2, overvoltage category III, so it's rated for fixed-installation mains supply points. Sealable, halogen-free, silicon-free — relevant for installations that require tamper-evident sealing or where outgassing-sensitive equipment (contactors, electronics) shares the enclosure.
Electrical ratings and operating conditions
Single-phase operation at 250 V; multi-phase at 440 V maximum. DC rated at 72 V maximum — suitable for DC branch protection only at low voltage, not for typical 110 V or 220 V DC buswork. Mechanical service life 10 000 operating cycles typical.
