The B-curve trips between 3 and 5 times rated current, so it's sized for resistive and light inductive loads — think lighting circuits, socket outlets, or small control transformers — not motor starts that would nuisance-trip a B-curve. The 10 kA SCCR at 400 V means it safely interrupts fault currents up to that level without cascading upstream, which is the standard for most commercial and light industrial distribution boards. ## Lifecycle and compliance Listed as Active (current production) by Siemens, so this is a standard catalog item — no end-of-life notice, no last-time-buy pressure. RoHS compliant since June 2013, with a REACH Article 33 declaration for lead (CAS 7439-92-1) above 0.1% w/w. The product class is B (return restricted), meaning Siemens directs inquiries through their partner or contact channel — standard for breakers sold through distribution. ## Sourcing and fit Part of the 5SL4 Basic Devices family, Group Code P310, Product Group 3822. Mounts on standard 35 mm DIN rail — snap-on, no tools needed. The 1-pole format takes one module width (17.5 mm). For volume or BOM-line sourcing, this is quoted to order against an RFQ; availability and current pricing confirmed at quote time.","metaTitle":"Siemens 5SL4140-6CC Miniature Circuit Breaker, 1-pole, B, 40","metaDescription":"Siemens 5SL4140-6CC miniature circuit breaker, 1-pole, B-curve, 40 A, 230/400 V, 10 kA breaking capacity.
