Rated for AC 690 V and DC 600 V, it covers most industrial supply voltages short of medium-voltage gear. It connects via busbar or front-terminal main current connections, which suits panel layouts where the disconnect bolts directly to a bus riser rather than landing on cables. The 3VA1450-1AA42-0AA0 measures 248 mm high, 184 mm wide, and 110 mm deep. It mounts in the standard MCCB cutout footprint for the 3VA1 frame, so if you are replacing a 3VA1 or similar-frame SENTRON disconnect, the panel cutout and busbar centres carry over without rework. IP40 on the front keeps dust and tools out; the rear and sides are open to the enclosure, so the panel itself provides the IP rating. The disconnect ships with a nut-keeper kit for busbar mounting. No auxiliary contacts, no undervoltage release, and no communication function are fitted on this variant, so it is a pure mechanical isolator. If you need a shunt trip or aux switch later, the product extension option for a motor drive is listed as available, but the auxiliary release design is specified as 'without' on this order code. Typical mechanical service life is 15,000 operating cycles. Maximum power loss is 120 W at rated current.","metaTitle":"Siemens 3VA1450-1AA42-0AA0 SENTRON Switch Disconnector, 500","metaDescription":"Siemens SENTRON 3VA1450-1AA42-0AA0 switch disconnector, 500 A rated current, 4-pole, MCCB design, 690 V AC / 600 V DC.
