Product details

The 55 mm width and 149 mm depth fit standard panel layouts; clearance requirements are 50 mm upward, 50 mm downward, and 10 mm to the side — no extra space needed forward or backward.

Integration Notes

Screw-type terminals on the main circuit accept 2×(1–25 mm²) or 1×(1–35 mm²) solid or stranded copper. Terminal size M6 for the main contacts. Temperature compensation is active across the -20 to +60 °C operating range. Maximum switching frequency under AC-3 duty is 15 operations per hour — adequate for motor starting applications but not for high-cycling loads like rapid reversing or jogging. For higher duty cycles, consider a contactor with a higher mechanical life rating.

Frequently asked questions

Where can I buy 3RV2031-4VA10-ZW97 and get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is the breaking capacity of 3RV2031-4VA10-ZW97 at 400 V?

The breaking capacity at 400 V is 30 kA. At 690 V it is 2 kA, and at 240 V it is 100 kA.

Will 3RV2031-4VA10-ZW97 drop into a panel specified around 3RV1011-1HA10?

The 3RV2031-4VA10-ZW97 is a SIRIUS motor protection circuit breaker with a 55 mm width and DIN-rail mounting, similar in form factor to the 3RV1011 series. However, verify the terminal size and clearance requirements against your existing panel layout — the 3RV2031 uses M6 main terminals and requires 50 mm upward clearance, which may differ from the 3RV1011.
