It uses a TM210 thermal-magnetic trip unit with fixed overload protection set at Ir=45 A and fixed short-circuit protection at Ii=10 x In (450 A). This is a line-protection breaker — no ground-fault or electronic trip adjustments — so the trip settings are locked at the factory. For a panel builder, that means no calibration step during commissioning, but also no field adjustment if the load changes. The 65 kA interrupting rating at 277 V puts it in the high-breaking-capacity class H, sized for service-entrance or large distribution panels where fault currents are substantial. One pole, so it's a single-phase or DC branch breaker — not a 3-phase main. Mounts in a standard panelboard or switchboard enclosure; the UL Frame 125 footprint matches the 3VA4 family's modular bus connections. RoHS compliant since 13-05-19. Packaging dimensions are 472 x 396 x 213 mm, shipped as 1 piece per unit.","metaTitle":"Siemens 3VA4145-6ED14-3AA0 Circuit Breaker, 45A, 65kA @ 277V","metaDescription":"Siemens 3VA4145-6ED14-3AA0 circuit breaker, 45A, 65kA interrupting at 277V, 1-pole, UL Frame 125.
