Breaking capacity is 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC. That 50 kA at 400 V covers most industrial panel fault-current levels up to a 2000 kVA transformer secondary. The auxiliary switch is transverse design, rated 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V — sufficient for signaling to a PLC input or contactor coil, but watch the DC derating if driving an inductive load. Power dissipation in hot operating state is 19 W. Operating frequency is limited to 15 switching cycles per hour at AC-3 duty; this is a motor-protection device, not a high-cycle contactor. Any mounting position is allowed. Backwards and side clearances are 0 mm — no air gap needed, which simplifies panel layout when stacking breakers side by side. Dimensions are 55 mm wide × 140 mm high × 149 mm deep. Main circuit terminals accept solid wire 2×(0.5–1.5 mm²) and 2×(0.75–2.5 mm²), stranded wire 2×(0.75–25 mm²) and 1×(0.75–35 mm²), or AWG 2×(18–2) and 1×(18–2). That 35 mm² stranded capacity on a single conductor is generous for a 32 A breaker — useful for long cable runs where voltage drop drives larger gauge. Shock resistance is 25 g for 11 ms. RoHS compliance date is July 1, 2006 — the part is RoHS-compliant for EU markets. Lifecycle stage is marked as current production. This is an active catalog item, not a phase-out or obsolete line.","metaTitle":"Siemens 3RV1031-4EA15-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1031-4EA15-ZW96 SIRIUS motor protection circuit breaker, 32 A continuous, CLASS 10 trip, 50 kA at 400 V AC.
