Product details

The Siemens SENTRON 3VA1112-5EF36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated 125 A at 40 °C, with a TM240 thermal-magnetic overcurrent release. At 415 V the rating drops to 121 kA, at 440 V to 75.6 kA, and at 500 V and 690 V to 17 kA; this is typical for an MCCB where arc extinction gets harder as voltage rises.

The breaker holds its full 125 A rating from 40 °C up to 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep; the 76.2 mm width is three standard 25.4 mm pole pitches, so it fits a standard DIN-rail or panel-mount footprint without extra adapters. Power loss is 30.6 W maximum — account for that in the enclosure thermal calculation.

Frequently asked questions

What are the key ratings for the 3VA1112-5EF36-0DA0?

It is a 3-pole MCCB rated 125 A at 40 °C, with breaking capacities of 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The overcurrent release is TM240; it includes an undervoltage release.

Will the 3VA1112-5EF36-0DA0 fit a panel designed for the 3VA1112-5EE32-0AA0?

Both are 3-pole SENTRON MCCBs with the same 130 mm height, 76.2 mm width, and 70 mm depth, so the physical footprint is identical. The difference is in the overcurrent release and the breaking capacity — the 5EE32 variant uses a different trip unit. If the panel was cut for the 5EE32, this breaker drops in without rewiring, but verify the coordination study still holds with the TM240 release.

How do I get current pricing and availability for the 3VA1112-5EF36-0DA0?
