The Siemens 3VA4170-6ED24-3AA0 is a 2-pole molded-case circuit breaker from the 3VA4 family, built on a UL Frame 125 platform. It carries a 65 kA interrupting capacity at 480 V — class H — meaning it can clear a bolted fault up to that level without welding its contacts or rupturing the case. That rating governs its use in high-available-fault-current panels where a standard 25 kA or 35 kA breaker would need an upstream current-limiting fuse or a larger frame. The TM210 thermal-magnetic trip unit is set with a fixed overload protection Ir of 70 A and a fixed short-circuit pickup Ii of 10 × In (700 A). No field-adjustable dials for Ir or Ii; the breaker ships at those values and stays there. That locks the application to a 70 A continuous load — typically a feeder or a large motor branch where the full-load amps land at or under 70 A and the inrush does not exceed 700 A peak.
Sourcing and availability
This breaker is a standard catalog item, sourced through Siemens distribution and stocked by independent channels. For volume or scheduled deliveries, submit an RFQ — availability and current pricing are confirmed at quote time. The product class C designation means it is manufactured to order and not returnable for credit once shipped, so confirm the order code and ratings before committing.
