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.","metaTitle":"Siemens 3RV1011-0KA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1011-0KA20-ZX95 SIRIUS motor protection circuit breaker, 1.25 A continuous, Class 10 trip, 100 kA breaking at 400 V.

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."},{"question":"Will 3RV1011-0KA20-ZX95 drop into a panel specified around 3RV1011-0GA10?","answer":"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."},{"question":"What compliance documentation is available for 3RV1011-0KA20-ZX95?","answer":"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.
