The 25 kA @ 480 V SCCR is the key coordination number for the panel designer. If the utility transformer can deliver more than 25 kA symmetrical at the breaker line terminals, this breaker is not the right series — you need the higher-breaking class H or L within the 3VA family. Below that threshold, it coordinates cleanly with downstream branch breakers sized for the load. ## Lifecycle and procurement posture RoHS compliant since 13-05-19. REACH Article 33 disclosure applies: Lead CAS-No. 7439-92-1 > 0.1% w/w in certain components. Export controls are AL:N / ECCN:EAR99 — no special licensing for most destinations, but verify against your end-use if it's a controlled facility.","metaTitle":"Siemens 3VA4140-4ED34-3AA0 Circuit Breaker, 40 A, 25 kA @ 48","metaDescription":"Siemens 3VA4140-4ED34-3AA0 circuit breaker, 3-pole, 40 A, 25 kA @ 480 V, active production.
