Its 30 kA interrupting capacity at 400 V AC tells you it can safely clear a fault up to that level without upstream devices needing to coordinate — a key figure when you're sizing the panel's SCCR. The rated operational voltage spans 20 to 690 V, covering common low-voltage three-phase systems from 208 V to 600 V classes. ## Mounting and integration Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, with any mounting position allowed. The 55 mm width and 149 mm depth fit standard panel layouts; clearance requirements are 50 mm upward and downward, 10 mm to the side, and zero forward or backward. Main circuit terminals accept 2x 1…25 mm² or 1x 1…35 mm² solid or stranded copper, terminated with M6 screws.","metaTitle":"Siemens 3RV2331-4UC10 SIRIUS Circuit Breaker, 30 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV2331-4UC10 circuit breaker for starter combinations. 30 kA interrupting capacity at 400 V AC.
