Product details

The 3VA1112-5GD42-0AA0-ZD00 is a Siemens 3VA1 IEC frame 160 molded-case circuit breaker with a 125 A fixed thermal-magnetic trip (TM210) and a making/breaking capacity of 55 kA at 415 V AC — class M. The 4-pole construction with 100% N-conductor protection (full-rated neutral) makes it suited for four-wire systems where the neutral carries load current, common in commercial and light-industrial distribution.

Deployment context

The nut keeper kit included (for DC Power OEM in China) simplifies bus-bar installation in DC applications, though the breaker itself is rated for AC distribution.

Frequently asked questions

Where can I buy 3VA1112-5GD42-0AA0-ZD00 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the closest alternative to 3VA1112-5GD42-0AA0-ZD00 in this family?

Within the 3VA1 frame 160 family, the closest standard variant is the base 3VA1112-5GD42-0AA0 (without the -ZD00 suffix). The -ZD00 suffix adds the nut keeper kit for DC Power OEM in China. If that kit is not needed, the base order code is a direct substitute; if the kit is required, this exact -ZD00 variant is the correct fit.

What is 3VA1112-5GD42-0AA0-ZD00's listed lifecycle stage?

The lifecycle stage is current.

What compliance documentation does Siemens provide for this breaker?

Standard Siemens 3VA1 breakers carry IEC 60947-2 certification. The evidence does not list UL, CSA, RoHS, or REACH documentation specifically for this order code; verify with the manufacturer or your compliance team for the exact project requirements.
