At 55 mm wide it takes one standard module slot — leaves room for the contactor and overload block next to it. Mounting position any — horizontal, vertical, upside-down, doesn't care. Depth 149 mm, width 55 mm, height 140 mm. Main contact terminals take M6 screws; solid or stranded wire up to 2x 2.5 mm².","metaTitle":"Siemens 3RV2031-4DB15-ZX95 SIRIUS Motor Protection CB, 30 kA","metaDescription":"Siemens 3RV2031-4DB15-ZX95 SIRIUS motor protection circuit breaker, 30 kA at 400 V, Class 20, 55 mm wide, DIN rail mount.

Check your fault current study — if the panel requires 30 kA, the 3RV2031 is the correct fit; if the original spec was lower, the 3RV2031 still works but costs more.
