That's unusual for a molded-case-style device; most MCCBs start shedding current at 40 °C. Here it holds flat. The shunt trip (STL) release is rated for 110-127 V DC and AC 50/60 Hz, so it'll drop the disconnect on a remote signal from an E-stop or safety relay. ## Where It Goes in a Panel This is a front-terminal clamp connection, so you land the main circuit conductors on the front face — no rear-connect bus bar required. The dimensions are 70 mm deep, 76.2 mm wide (that's 3 inches exactly), and 130 mm tall. That's not trivial — if you're packing several of these in a small enclosure, you'll want to account for the heat rise. Mechanical service life is 15,000 operating cycles typical, so it's built for frequent switching in a disconnect role, not just infrequent isolation. If your panel runs hot near a motor drive or a furnace wall, this disconnect won't force you to oversize the frame just to hold rating. The insulation voltage is rated 800 V, operating voltage 690 V AC and 500 V DC, so it covers 480 V and 600 V class systems with margin. The shunt trip is the main reason you'd pick this variant over a plain disconnect. It's a 110-127 V coil, so it works on common control voltages in North America (120 V) and Europe (110 V) without a transformer tap. No undervoltage release on this unit — if you need UVR, that's a different order code.","metaTitle":"SENTRON 3VA1163-1AA36-0JH0 Switch Disconnector, 63 A, 3-Pole","metaDescription":"SENTRON 3VA1163-1AA36-0JH0 switch disconnector, IEC frame 160, 3-pole, 63 A continuous rating, shunt trip STL 110-127 V DC/AC, IP40 front.

For a pure switch disconnector replacement, stay within the 3VA1 switch disconnector family; the 3VA1163-1AA36-0JH0 is the 63 A shunt-trip variant. A breaker cannot substitute where intentional no-overload disconnection is required."},{"question":"Will 3VA1163-1AA36-0JH0 fit in a panel designed for 3VA1110-5EF32-0AM0?","answer":"Both share the same physical footprint: 70 mm deep, 76.2 mm wide (3 inches), 130 mm tall. The mounting pattern and front terminal layout are identical, so it will drop into the same DIN rail or panel cutout without rewiring the main conductors. The auxiliary switch wiring differs (2 HQ + 1 trip alarm vs 2 HQ + 1 short-circuit alarm), so check the control wiring diagram."},{"question":"What compliance documentation is available for this SENTRON part?","answer":"As a standard Siemens SENTRON product, it carries IEC 60947-3 certification for switch-disconnectors.
