It is explicitly not a circuit breaker: no overload or short-circuit protection elements are fitted. Its job is safe isolation under load, not fault interruption. The built-in shunt trip (STL) coil rated 110–127 V DC / AC 50/60 Hz provides remote tripping for emergency-stop or interlock circuits. ## Continuous current and thermal limits Above that the derating curve is gradual: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, 150 A at 70 °C. The maximum power loss is 38 W, which sets the ventilation requirement in a sealed enclosure. For a panel OEM doing a thermal budget, that 38 W is the number to plan around — not the nameplate current. ## Voltage ratings and connection scheme Rated insulation voltage 800 V; operating voltage 690 V AC and 600 V DC. The main circuit terminals are front-entry, designed for busbar connection — not cable lugs. Width is 101.6 mm (4-pole), depth 70 mm, height 130 mm. Fits the standard MCCB cutout pattern, but verify the busbar adapter pitch against your existing panel layout. ## Mechanical endurance and auxiliary wiring Rated for 15 000 mechanical operating cycles typical. Three CO contacts are available across the auxiliary and alarm switches. The shunt trip occupies one auxiliary slot; the two HQ aux switches and the trip alarm switch fill the rest. If you need more than three CO contacts total, an external aux block is required — the internal bay is fully populated as shipped.","metaTitle":"3VA1116-1AA42-0JH0 SENTRON Switch Disconnector, 160A 4-Pole","metaDescription":"SENTRON 3VA1116-1AA42-0JH0 switch disconnector in MCCB design, 160A at 40°C, 4-pole, 690V AC / 600V DC.
