Rating and deployment context
The Siemens 5SL6114-8CC is a 1-pole miniature circuit breaker rated at 0.3 A with a D tripping characteristic, breaking 6 kA at 230/400 V AC. The D-curve (10-20× In) is designed for loads with high inrush currents — typically motor starters, small transformers, or solenoid banks — where a B or C curve would nuisance-trip on start-up. At 0.3 A this is a low-current branch protection device, not a main feeder breaker.
Lifecycle and sourcing
Listed as current production (Active). The 5SL series remains a standard Siemens panel component, widely specified in European-origin distribution boards and sub-distribution panels. Sourced to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
