Product details

The thermal-magnetic trip unit (TM220, ATFM) gives you adjustable overload protection: Ir is settable from 224 A to 320 A, so you dial in the continuous current to match the cable or load, not the other way around. The instantaneous short-circuit pickup is fixed at Ii=10 x In, meaning it trips magnetically at 3200 A for a bolted fault. The N conductor is protected at 100%, which matters for 4-wire systems where the neutral carries harmonic current.

The 4-pole configuration with 100% N protection means it occupies four module widths — plan your gland plate and busbar takeoff accordingly. The nut keeper kit is a detail that saves time on the DC Power OEM line: it holds the terminal nuts captive during wiring, so a panel builder doesn't chase dropped hardware inside the enclosure.

Frequently asked questions

Where can I buy 3VA1332-4GE42-0AA0-ZD00 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not a stock count on a shelf.

What is the closest alternative to 3VA1332-4GE42-0AA0-ZD00 in the 3VA family?

The closest sibling would be a 3VA1 frame breaker with the same IEC frame 400, breaking capacity class S, and TM220 ATFM trip, but without the DC Power OEM nut keeper kit suffix (ZD00). The ZD00 suffix adds the nut keeper kit for captive-terminal wiring on the DC Power OEM line — the base breaker without that suffix is functionally identical for the trip curve and interrupting rating, but lacks the captive hardware. No pin-compatible alternative exists outside the 3VA1 series; the mounting footprint and busbar connection pattern are specific to the 3VA1 frame.

What compliance documentation is available for this breaker?

The Siemens 3VA1 series carries IEC certification (IEC 60947-2) as standard. For specific RoHS, REACH, or UL documentation, the manufacturer provides declarations of conformity and material compliance data on request. The order code suffix indicates a DC Power OEM variant for China, so expect the documentation set to include the China RoHS declaration.
