Motor-protection circuit breaker, 3.2 A, Class 10 — SIRIUS
The Siemens 3RV1011-1DA15-0BA0 is a SIRIUS motor-protection circuit breaker rated for 3.2 A continuous current, with a thermal overload release (Class 10) and a magnetic short-circuit trip. It switches motor loads up to 1.1 kW at 400 V AC. Breaking capacity reaches 100 kA at 240 V and 400 V AC, dropping to 3 kA at 500 V and 2 kA at 690 V — the high 100 kA figure at 400 V means it can be used on high-fault-capacity industrial networks without requiring an upstream current-limiting fuse for most installations. Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, in any position. The 45 mm width and 81 mm depth fit standard panel layouts; IP20 on the front means it is protected against finger contact but not washdown.

Auxiliary switch and wiring
The auxiliary switch is transverse design and the product extension for an auxiliary switch is available. Main and control circuit terminals are screw-type, accepting solid and stranded conductors: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²). Auxiliary contact ratings: 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V — these are the switching capacities for the signal circuit, not the main motor current.
