Product details

What this MCCB does on the line

The Siemens SENTRON 3VA2125-7HM46-0AA0 is a 4-pole molded case circuit breaker rated for 25 A continuous current, with an adjustable thermal-magnetic trip unit covering 38 A to 300 A. Breaking capacity reaches 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. It is a standalone protective device, not a smart breaker.

No rewiring is needed if replacing a same-frame 3VA breaker; the mounting footprint and busbar connections are identical across the series.

Frequently asked questions

What are the key ratings for 3VA2125-7HM46-0AA0?

It is a 4-pole, 25 A continuous MCCB with an adjustable trip setting from 38 A to 300 A. Breaking capacity is 330 kA at 240 V AC, 242 kA at 415 V, and 3.7 kA at 690 V. Rated insulation voltage is 800 V.

Will 3VA2125-7HM46-0AA0 drop into a panel specified around 3VA2163-8HM32-0AA0?

Both are SENTRON 3VA frame breakers with the same 140 mm width, 86 mm depth, and 181 mm height, so the physical footprint is identical. The 3VA2125-7HM46-0AA0 has a lower continuous rating (25 A vs the 3VA2163's higher rating) and different trip settings, but it mounts on the same busbar and DIN-rail pattern without rewiring.

Where can I buy 3VA2125-7HM46-0AA0 and how is it quoted?

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 compliance documentation does Siemens provide for this MCCB?

As a SENTRON series product, the 3VA2125-7HM46-0AA0 carries IEC 60947-2 certification for molded case circuit breakers. Siemens provides a declaration of conformity covering the Low Voltage Directive, RoHS, and REACH compliance on request.
