MCCB for high-fault panel feeders
The 187 kA breaking capacity at 240 V and 121 kA at 415 V give it headroom on high-fault panels where upstream transformer or generator capacity pushes available fault current above typical 65 kA or 100 kA MCCB ratings.
Above that it derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
The 3VA1116-5EF36-0CC0 delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
Auxiliary contacts and release options
The auxiliary contacts provide status feedback — open/closed indication to a PLC or remote I/O. There is no voltage trigger, no communication function, no phase failure detection, and no ground fault monitoring on this version. The auxiliary release order code for the UVR is 3VA9608-0BB24.
The 3-pole design handles three-phase feeders; the line protection version is intended for cable and busbar protection, not motor overload duty (that would require a separate overload relay or a motor-protective MCCB variant).
