Product details

That's a solid spec for a motor branch circuit that sees seasonal ambient swings. The UVR drops the breaker if supply voltage falls below a set threshold, which keeps a motor from trying to start under brownout conditions. Phase failure detection catches a lost leg before single-phasing cooks the winding.

Interrupting capacity — what those numbers mean for your fault current

This MCCB is rated to interrupt 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. At 415 V, the 121 kA rating still covers most distribution panels. The sharp drop to 3.7 kA at 690 V tells you this breaker is not intended for 690 V motor circuits with high available fault current; it's sized for the 240–500 V range where the interrupting capacity stays well above typical panel SCCR requirements.

Panel fit and auxiliary configuration

That's a standard SENTRON 3VA2 footprint — it bolts into the same mounting pattern as other 3VA2 frames in the family. That's enough status feedback for a remote PLC to know whether the breaker is on, tripped on fault, or switched off manually — no need to add separate aux blocks for basic monitoring.

Frequently asked questions
