It is a current-production part in the active SIRIUS catalog. Trip Class 10 means it will trip within 10 seconds at 7.2× the thermal setting — the standard fit for standard induction motor starts (conveyors, pumps, fans) where the start is under a few seconds. Phase failure detection is built in: if one line drops, the breaker opens before the motor single-phases to failure. ## Key ratings and what they mean for your panel At 400 V the breaker is rated gL/gG 50 A — that is the maximum short-circuit current it can safely interrupt with a gL/gG backup fuse. At 690 V the interrupting capacity drops to 4 kA, so verify the available fault current at your service voltage. The auxiliary contact ratings cover the control circuit: 1 A at 24 V, 0.5 A at 120/230 V. That is enough to signal a PLC input or drop out a contactor coil, but not enough to switch a motor load directly. Mounting position is any, and the breaker snaps onto standard 35 mm DIN rail per DIN EN 60715 — no panel layout restrictions. ## Dimensions and panel fit Width is 45 mm, depth 97 mm, height 97 mm. The 45 mm width is a single modular unit on the DIN rail — matches the footprint of a standard miniature circuit breaker for clean row alignment. Clearance requirements: 50 mm above and below, 30 mm to the side. Keep those gaps free for cooling and arc-chamber venting.","metaTitle":"Siemens 3RV2011-1GA15-ZX95 Motor Protection Circuit Breaker,","metaDescription":"Siemens SIRIUS 3RV2011-1GA15-ZX95 motor protection circuit breaker, Class 10 trip, 50 A gL/gG at 400 V, phase failure detection.
