The Siemens 3VA1125-6GD42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker from the 3VA1 series, configured for line protection with a fixed thermal-magnetic trip unit (TM210, FTFM). The breaker is rated In = 25 A continuous current, with fixed overload protection at Ir = 25 A and fixed short-circuit protection at Ii = 12.8 × In (320 A). The 100% N conductor protection means the neutral pole is fully rated, not reduced — this matters for systems with harmonic loads or where the neutral carries near-phase current.

Frequently asked questions
Where can I buy 3VA1125-6GD42-0AA0-ZD00?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
What does the 100% N conductor protection mean?
It means the neutral pole is rated for the full phase current, not a reduced rating. This is necessary when the neutral carries significant current from non-linear loads or phase imbalance.
