Product details

Motor protection circuit breaker — 10 A, CLASS 10, 100 kA

Breaking capacity is 100 kA at 240 V and 400 V AC, dropping to 42 kA at 500 V and 6 kA at 690 V. No ground fault detection on this unit, so that's a separate device if needed.

At 45 mm wide, it takes a single 9 mm module width on the rail. Depth is 96 mm, height 97 mm — standard SIRIUS footprint, so it drops into existing Siemens motor starter assemblies or standalone DIN-rail enclosures without panel rework.

Termination and aux contacts

Main circuit terminals are screw-type, accepting solid conductors 2× (0.5 to 1.5 mm²) and 2× (0.75 to 2.5 mm²), or stranded 2× (1 to 2.5 mm²) and 2× (2.5 to 6 mm²). That covers most motor power wiring up to 4 mm² — typical for a 10 A motor circuit. An auxiliary switch is included, rated 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V. The auxiliary switch design is transverse. No additional auxiliary contact blocks are fitted (: 0 for auxiliary contacts).

Frequently asked questions
