The Siemens Betagard 5SL7310-3RC is a 3-pole miniature circuit breaker with a K tripping characteristic, rated 10 A at 415 V AC and a 15 kA breaking capacity per both EN 60898 and IEC 60947-2. The K characteristic means it's designed to handle moderate inrush currents — think motor loads, transformers, or solenoid valves — without nuisance tripping, while still providing short-circuit protection. It's rated for single-phase operation up to 440 V and multi-phase up to 440 V as well, so it covers standard 400 V three-phase distribution.
Deployment context
The 3-pole footprint at 54 mm wide fits a typical 3-module slot in a distribution board or sub-panel. Sealable per the spec — useful if the panel needs to be locked or tagged after commissioning.
