Any mounting position is permitted, so vertical or horizontal rail orientation is fine. The interrupting capacity varies by system voltage: 100 kA at 240 V, 30 kA at 400 V, 5 kA at 500 V, and 2 kA at 690 V. At 400 V — the most common industrial distribution voltage — the 30 kA rating means this breaker is suitable for installations with a transformer rating up to about 2 MVA (assuming 6% impedance). Main circuit terminals are screw-type, accepting 2x 1–25 mm² or 1x 1–35 mm² solid or stranded copper. The M6 main contact studs are sized for the full rated current. No ground-fault or phase-failure detection is built in — those functions would need to be handled upstream or by an external relay.","metaTitle":"Siemens SIRIUS 3RV2331-4VC10 Circuit Breaker, 30 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV2331-4VC10 circuit breaker for starter combinations. 30 kA interrupting capacity at 400 V.

This is the rating that governs fault clearing in a 400 V distribution system — it will safely interrupt faults up to that level without cascading upstream."},{"question":"Will 3RV2331-4VC10 drop into a panel specified around 3RV2023-4DA10?","answer":"Both are SIRIUS circuit breakers on the same DIN rail footprint, but the 3RV2331-4VC10 is a higher-frame device designed for starter combinations with a 30 kA interrupting capacity at 400 V versus the lower-rated 3RV2023 series.
