Product details

Integration Notes

Mounts directly onto the 3RV breaker via the accessory slot on the left-hand side. No additional wiring is needed beyond the control circuit — the release shares the breaker's line-side terminals. Panel builders should verify the control voltage matches the line supply before commissioning. Compatible with frame sizes S00, S0, S2, and S3. The same release fits across the entire motor-protective breaker family, simplifying spare parts stocking for a mixed panel lineup.
