The fixed Ir=125 A means the overload pickup is set at the factory; no dial to adjust, so the breaker is sized to the conductor and load, not tuned after installation. The Ii=10 × In short-circuit pickup (1250 A) is also fixed, so it will ride through moderate motor inrush but trip fast on a hard bolted fault. Terminal connection — no plug-in base — so it bolts directly to the bus or cable lugs in the panel.

Frequently asked questions
Where can I buy 3VM1112-3ED16-0AA2 and 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 breaking capacity of 3VM1112-3ED16-0AA2?
The breaking capacity is Icu=25 kA at 240 V, 1-pole, which is the class N rating for the IEC frame 160 platform.
What does the TM210 trip unit mean on this breaker?
TM210 means a thermal-magnetic fixed trip: overload protection is fixed at Ir=125 A (not adjustable), and short-circuit protection is fixed at Ii=10 × In (1250 A). The FTFM designation confirms fixed thermal, fixed magnetic release.
