Breaking capacity hits 65 kA at 240 V and 400 V AC, dropping to 8 kA at 500 V and 2 kA at 690 V — the 400 V figure is the one that matters for most European and Asian distribution panels. Width is 55 mm — that's three standard 18 mm module slots, so plan for it in a crowded enclosure. Depth is 149 mm, height 140 mm. Main circuit terminals are screw-type, accepting 2x 1–35 mm² or 1x 1–50 mm² solid or stranded copper. Torque to M6 specs — clean termination, no spring-clip surprises. ## Environmental and Operating Limits Maximum switching rate is 15 operations per hour at AC-3 or AC-3e duty — fine for transformer switching, not for a high-cycle motor start application. That matches the transformer protection role — phase loss is the primary risk, and ground fault is handled downstream. Lifecycle status is current production — this is an active Siemens catalog number, not a phase-out or NRND line item.","metaTitle":"Siemens 3RV2431-4XA10 SIRIUS Circuit Breaker, 55 mm, 65 kA a","metaDescription":"Siemens 3RV2431-4XA10 SIRIUS circuit breaker for transformer protection.
