Product details

Its breaking capacity is 100 kA at 400 V AC and 10 kA at 690 V AC. Trip Class 10 means the bimetal releases within 10 seconds at 7.2× the thermal setting — fast enough to protect standard IEC induction motors from stall or locked-rotor conditions. The 45 mm wide housing clips onto 35 mm DIN rail per EN 60715, with a 97 mm depth that leaves room for wiring behind the panel door. Spring-loaded terminals accept 2× (0.5 to 4 mm²) solid or stranded — no screw torque to verify, just strip and push.

Integration — what fits alongside it

Clearance requirements: 50 mm above and below, 30 mm to the side, zero forward or backward. Operating temperature range is -20 to +60 °C, storage -50 to +80 °C. Spring-loaded terminals on the main circuit reduce wiring time on a panel build. The auxiliary contact block (not included) clips onto the side without increasing width — order separately if remote status or PLC feedback is needed.

Frequently asked questions

Will 3RV2011-1BA20-ZX95 drop into a panel specified around 3RV2011-0BA20 without rewiring?

The 3RV2011-1BA20-ZX95 shares the same 45 mm width, DIN-rail mounting, and spring-loaded terminal layout as the 3RV2011-0BA20. Physical fit and wiring are identical — the difference is in the internal trip setting range and accessories. Confirm the overload setting matches your motor FLA before swapping.
