At 415 V it still holds 121 kA, and at 690 V it's 52.5 kA — so the same unit handles high-fault service entrances and distribution feeders across voltage tiers. The UVR means the breaker drops out if control voltage is lost, which is standard for emergency-stop or safety-shutdown circuits where you want the load isolated on power loss. At 55 °C it's 780 A; at 60 °C it's 761 A; at 65 °C it's 741 A; at 70 °C it's 722 A. Above that, you size the load or the ventilation around the derated figure. Dimensions: 210 mm wide, 320 mm tall, 120 mm deep. The 210 mm width is the pole pitch for a 3-pole frame; it's a standard SENTRON 3VA footprint, so if you're swapping into an existing 3VA panel, the bus-bar and lug positions should align without rework.","metaTitle":"Siemens 3VA1580-5EF32-0DH0 SENTRON MCCB, 800 A, 187 kA","metaDescription":"Siemens 3VA1580-5EF32-0DH0 SENTRON molded case circuit breaker, 800 A rated at 40 °C, 187 kA breaking at 240 V.
