Any mounting position is allowed. Rated operational voltage spans 20 to 690 V. At 230 V the motor rating is 0.1 kW; at 480 V and 600 V the setting range drops to 0.63 A — this is a low-current variant for fractional-horsepower motors or small transformer primary protection. The maximum back-up fuse is gL/gG 6 A at 690 V. With 100 kA SCCR at 240, 400, 500, and 690 V AC, it coordinates cleanly with most downstream contactors without separate current-limiting fuses. For comparison to the 3RV2011-0BA20: both are size S00 Class 10 breakers, but the -0BA20 carries a higher current setting range and lacks the spring-terminal variant — the -0GA20-ZX95 is the spring-terminal version with a narrower adjustment band. If your panel was wired for the -0BA20 with screw terminals, the -0GA20 will fit the same DIN rail footprint but you will need to adapt the conductor termination method.","metaTitle":"Siemens 3RV2011-0GA20-ZX95 SIRIUS Motor Protection CB, 100 k","metaDescription":"Siemens 3RV2011-0GA20-ZX95 SIRIUS motor-protection circuit breaker, size S00, Class 10 trip, 100 kA SCCR at 400 V, spring terminals.

The -0BA20 uses screw terminals instead of spring-loaded terminals and has a different current adjustment range.
