Product details

The Siemens 3VA4170-4ED34-3AA0 is a 3-pole molded case circuit breaker in the 3VA4 UL Frame 125 series, rated for line protection with a TM210 thermal-magnetic trip unit. Overload protection is fixed at 70 A (Ir = 70 A), and the short-circuit magnetic trip is set at 10× In (700 A).

SCCR and selectivity

The 25 kA interrupting rating at 480 V places this breaker in the S-class of the 3VA4 family. In a panel with a 65 kA available fault current, you'd need a current-limiting upstream breaker or fuse to coordinate — this breaker alone won't hold that. Pair it with a properly rated main, and the selectivity tables in the Siemens coordination manual apply.

Panel integration

The TM210 trip unit is non-interchangeable — Ir is fixed at 70 A, so if the load changes, the breaker itself must be replaced. Line and load lugs accept copper or aluminum conductors. The FTFM (fixed thermal, fixed magnetic) trip means no field adjustment of the magnetic pickup; it's locked at 10× In.

Frequently asked questions

What is the interrupting rating of this breaker?

The breaking capacity class S provides 25 kA at 480 V.

Can the overload protection setting be adjusted?

No, the TM210 trip unit has a fixed thermal setting Ir = 70 A and a fixed magnetic setting Ii = 10 × In (700 A). No field adjustment is possible.

What compliance documentation is available for the 3VA4170-4ED34-3AA0?

The part is RoHS compliant since 13-05-19 and carries a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w. Export control is AL: N / ECCN: EAR99.

Where can I buy the 3VA4170-4ED34-3AA0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
