Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V — numbers that matter when a turbine's converter bus or main feeder sees a stiff grid fault. ## Thermal derating — the real-world current Above that it steps down: 780 A at 55 °C, 761 A at 60 °C, 741 A at 65 °C, and 722 A at 70 °C (–). The 240 W maximum power loss also needs to be ventilated out of the enclosure; that's not trivial in a sealed offshore cabinet. The breaker measures 210 mm wide, 320 mm high, and 120 mm deep. That 210 mm width is a standard 8.27-inch footprint for this class of SENTRON MCCB. The 120 mm depth (4.72 in) leaves reasonable gutter space behind the panel door for wiring and the shunt trip connections. ## Key features at a glance Line-protection design with no communication function, no undervoltage release, and no ground-fault monitoring. The shunt trip (STL) auxiliary release allows a remote trip signal — useful for emergency-stop chains or SCADA-driven isolation. The TM240 thermal-magnetic release gives fixed thermal and magnetic pickup settings. The closest functional peer in the same SENTRON family is the 3VA1110-5EF32-0LA0. The critical difference is the continuous current rating: the 3VA1580 carries 800 A at 40 °C, while the 3VA1110 is a lower-frame model. Both share the 3-pole form, shunt trip, and similar breaking capacities at the same voltage points, but the 3VA1110 frame physically cannot deliver the 800 A continuous rating. If your BOM specifies 800 A, the 3VA1580-5EF32-0JA0 is the correct frame; the 3VA1110 will not drop in without a redesign.","metaTitle":"Siemens 3VA1580-5EF32-0JA0 SENTRON MCCB, 800 A, 3-Pole, 187","metaDescription":"Siemens 3VA1580-5EF32-0JA0 SENTRON molded case circuit breaker, 800 A at 40 °C, 3-pole, 187 kA at 240 V.
