Circuit breaker 3VA4145-6ED24-3AA0 — 45 A, 65 kA @ 480 V, 2-pole
The Siemens 3VA4145-6ED24-3AA0 is a 2-pole molded case circuit breaker, UL Frame 125, rated 45 A continuous with fixed thermal overload (Ir=45 A) and fixed short-circuit pickup (Ii=10 x In). Its H-class breaking capacity is 65 kA at 480 V. The TM210 trip unit provides line protection only (no ground-fault or electronic adjustment), so this breaker is sized for straightforward feeder or branch-circuit duty where the load current is known and stable. The fixed Ir and Ii settings eliminate field calibration errors but also mean the breaker must be selected to match the conductor ampacity exactly — there is no adjustment band to compensate for an undersized or oversized selection.
Lifecycle and sourcing reality
RoHS compliance is confirmed since 13-05-19. The REACH Article 33 declaration lists lead (CAS-No. 7439-92-1) above the 0.1% threshold, which must be communicated downstream if the breaker is incorporated into equipment placed on the EU market. Export control is AL: N / ECCN: EAR99, so no special licensing is required for most commercial shipments.
Panel integration and mounting
The 3VA4 frame mounts in a standard panel cutout or on a mounting plate; it is not a DIN-rail snap-on device. Packaging dimensions are 472.00 x 396.00 x 213.00 mm.
