At 240 V it handles 100 kA. Those are the numbers that determine whether this part survives a bolted fault on your line without welding its contacts shut or cascading upstream. For a 40 A motor circuit on a 400 V distribution panel, 50 kA SCCR is generous — it covers most industrial service entrances. Width 55 mm, depth 149 mm, height 140 mm. Side clearance: 10 mm. Upward and downward clearance: 50 mm each. Main terminals accept 2x 1–35 mm² or 1x 1–50 mm² solid/stranded, terminated with M6 screws. ## Protection logic and operating limits No ground fault detection on this variant. Rated operational voltage span 20–690 V. Maximum switching frequency in AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV2032-4UA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2032-4UA10 SIRIUS motor protection circuit breaker, 40 A rated at 480/600 V, CLASS 10 trip, 50 kA breaking at 400 V.
