The Siemens 5SL4520-8CC is a 1+N-pole miniature circuit breaker (MCB) rated 20 A with a D tripping characteristic, designed for 230 V AC systems and a 10 kA breaking capacity. The D curve means it tolerates higher inrush currents — typically used for motor, transformer, or lighting ballast circuits where the start-up surge would nuisance-trip a B or C curve breaker. This is a current-production part, still in active manufacture.
Compliance and documentation
RoHS compliant since 01-06-13. REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1% w/w in the candidate list — a standard declaration for this class of switchgear, not a functional restriction. Export control is AL:N / ECCN:N, so no special licensing for cross-border shipments.
Sourcing and availability
Product class B means return is restricted — contact your Siemens partner for order placement. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
