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.","metaTitle":"Siemens 3VA1112-5EF36-0DA0 SENTRON MCCB, 125 A, 187 kA","metaDescription":"Siemens SENTRON 3VA1112-5EF36-0DA0 molded case circuit breaker, 3-pole, 125 A at 40 °C, 187 kA at 240 V, undervoltage release.

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."},{"question":"How do I get current pricing and availability for the 3VA1112-5EF36-0DA0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
