On a furnace or process line where a single-phased motor can cause a costly shutdown, this breaker will drop the load when one phase is lost, preventing single-phase heating and winding damage. Terminal capacity accepts 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire, with M6 main contact bolts. Clearance: 50 mm above and below the device, 10 mm to the side. The 50 mm vertical clearance is the minimum to allow arc gases to vent and to keep heat from adjacent components from affecting the thermal trip. Rated operational voltage span is 20 to 690 V AC. The auxiliary contact ratings at various control voltages are provided: 1 A at 24 V, 0.15 A at 60 V, 0.5 A at 230 V, and 125 A at 400 V — note the 125 A at 400 V is likely a typographical artifact for the main contact rating; the auxiliary contacts carry lower currents as listed.","metaTitle":"Siemens 3RV2031-4PA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV2031-4PA15 motor protection circuit breaker.
