It carries no overload or short-circuit protection elements, so it functions purely as a load-break disconnect for isolation and switching duty on 690 V AC or 600 V DC circuits. The shunt trip (STL) release accepts 12-30 V DC or 24 V AC 50/60 Hz for remote tripping, and the auxiliary switch block provides 2 HQ form-C contacts plus 1 trip alarm switch — three CO contacts total. Mechanical service life is 15 000 operating cycles typical. ## Panel fit and integration — 101.6 mm wide, busbar connection The 3VA1116-1AA42-0HH0 occupies a 101.6 mm wide by 130 mm tall by 70 mm deep footprint — standard for a 4-pole MCCB-style device on a DIN rail or mounting plate. Main circuit connection is via busbar with front terminals, so plan for busbar routing and front-access termination. Maximum power loss is 38 W, which should be factored into enclosure thermal calculations.","metaTitle":"Siemens 3VA1116-1AA42-0HH0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0HH0 switch disconnector, 160 A continuous, 4-pole, IEC frame 160.
