It handles AC loads up to 690 V 50/60 Hz and DC circuits up to 600 V. This is a pure disconnect — no overload or short-circuit protection built in, so it relies on upstream protection. The front terminal accepts busbar connections, and the IP40 front rating means it's suited for enclosed panel mounting where tools are needed to access live parts. The 70 mm depth and 101.6 mm width match the standard 3VA1 frame footprint for panel layout. The integrated undervoltage release (UVR) is wired for 120-127 V AC 50/60 Hz. If the control voltage drops, the UVR trips the disconnect open — standard practice for preventing automatic restart after a power loss on machinery or conveyors. The 160 A frame and 4-pole configuration make this disconnect suitable for three-phase plus neutral isolation in distribution panels or machine supply circuits. The short-time withstand rating of 2 kA for both 0.5 s and 1 s tells you the disconnect can hold closed under fault current long enough for an upstream breaker to clear — coordination study required, but the number gives the selectivity engineer something to work with. The latching endurance of 15,000 operations covers frequent manual switching in process lines or maintenance disconnects.","metaTitle":"Siemens 3VA1116-1AA42-0CH0 Switch Disconnector, 160 A, 4-Pol","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0CH0 switch disconnector, 160 A rated continuous current, 4-pole, with undervoltage release 120-127 V AC, 2 aux switches + 1 trip alarm.

The disconnect is wider (101.6 mm vs 76.2 mm) due to the fourth pole. They share the same 70 mm depth and 130 mm height, so panel cutouts and busbar positions differ for the neutral pole."},{"question":"What compliance documentation is available for this part?","answer":"As a Siemens SENTRON IEC device, it carries the manufacturer's standard declarations for the 3VA series.
