Product details

The 45 mm width and 90 mm height are standard for the SIRIUS 3RV1 frame, so it occupies one 45 mm slot in a panel layout. Depth is 81 mm from the rail face — check gland plate clearance if the enclosure is shallow. Spring-loaded terminals on the main circuit accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. No backwards or side clearance needed; IP20 on the front.

Protection and auxiliary features

Ground fault detection is not included. Mechanical endurance is 100,000 operations on the main contacts. Maximum switching rate in AC-3 duty is 15 operations per hour.

Environmental and electrical ratings

Shock resistance is 25 g for 11 ms. Surge voltage withstand is 6 kV.

Frequently asked questions

What is the closest functional second-source to 3RV1011-0KA20-ZX95?

The 3RV1011-0GA10 is a close peer within the same SIRIUS 3RV1 frame. The 0KA20 variant carries a 1.25 A continuous rating and 0.37 kW at 400 V, while the 0GA10 is rated at a different current. Both share the same 45 mm width, DIN rail mount, and Class 10 trip — verify the motor FLA before substituting.

Will 3RV1011-0KA20-ZX95 drop into a panel specified around 3RV1011-0GA10?

Yes — same 45 mm width, same 90 mm height, same 81 mm depth, same screw/snap-on DIN rail mount. The terminal wiring capacity is identical. The only difference is the current rating and motor power; the 0KA20 is the lower-rated variant at 1.25 A / 0.37 kW.

What compliance documentation is available for 3RV1011-0KA20-ZX95?

As a Siemens SIRIUS product, this breaker carries CE marking for the European market and is designed to meet IEC/EN 60947-2 and 60947-4-1 standards. UL/CSA listings are typical for the 3RV1 series; confirm the specific file number with the order code at quote time.

Where can I buy 3RV1011-0KA20-ZX95 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent industrial distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for volume or single-piece requirements.
