The 76.2 mm width matches the 3VA1 frame-160 footprint, so it slots into a multi-unit distribution block alongside MCCBs or other disconnectors on the same busbar system. Maximum power loss is 38 W. Verify the enclosure thermal budget if densely packed. The 100 A rated continuous current (Iu) at 690 V AC means this disconnect can carry 100 A indefinitely without overheating — sized for a 100 A feeder or branch circuit. The 2 kA limited short-time withstand (1 s and 0.5 s) tells you this disconnect can survive a fault current of 2 kA for up to one second — enough for coordination with upstream protective devices that clear faster. It is not a circuit breaker, so it relies on an upstream breaker or fuse to interrupt fault current; the disconnect just needs to hold together until the upstream device opens.","metaTitle":"Siemens 3VA1110-1AA32-0JC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0JC0 SENTRON switch disconnector, 100 A rated continuous current, 3-pole, shunt trip STL 110-127 V DC/AC, 2 auxiliary switches HQ, IP40 front.

However, the 3VA1110-1AA32-0JC0 uses busbar connection while the 3VA1110-5EE32-0JA0 uses lug terminal connection, so the busbar arrangement may differ.
