The 3VA1112-5EF36-0JA0: Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V. The overcurrent release is TM240 (thermal-magnetic, 240 A frame), and the auxiliary release is a shunt trip (STL) — a separate control voltage trips the breaker remotely. Insulation voltage rated 800 V.
Three-pole width is standard for a 125 A frame. Maximum power loss 28.1 W.
Rated 125 A continuous at 40 °C (derates to 114 A at 70 °C), breaking capacity 187 kA at 240 V, 3-pole, TM240 thermal-magnetic release, shunt trip (STL) auxiliary release.
