Insulation voltage is rated 800 V, so it's comfortable on 480/277 V or 400/230 V systems without de-rating the insulation. This is not a motor-protection breaker — the product design is explicitly \"line protection,\" meaning it's sized for feeder and branch-circuit overcurrent protection, not for overload relay coordination on a motor start profile. If you're replacing a breaker on a pump or compressor feeder, this fits; if you need a combination motor starter, look at the 3VA1 with electronic trip for motor applications. ## DIN-rail footprint and thermal derating Dimensions are 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). The depth is 70 mm. Thermal derating is published stepwise: 80 A flat from 40 °C through 50 °C, then 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. If your panel ambient runs 55 °C+ (tightly packed enclosure, no forced air), you lose 2–6 A off the nameplate. ## Auxiliaries and accessories onboard The base switch is order code 3VA10803ED360AA0, so if you ever need a bare breaker without auxiliaries, that's the stripped variant.","metaTitle":"Siemens 3VA1080-3ED36-0JH0 SENTRON MCCB, 80A, 75.6kA","metaDescription":"Siemens 3VA1080-3ED36-0JH0 SENTRON molded case circuit breaker, 80A at 40°C, 75.6kA at 240V, 3-pole, line protection.
