It is built for isolation and safe disconnection under load — not for overload or short-circuit protection, which the description explicitly excludes. The front-mounted busbar connection and 70 mm depth suit it for panel integration where a compact, high-cycle disconnect is needed on a DIN-rail or mounting plate. Rated insulation voltage (Ui) is 800 V, with maximum operational voltages of 690 V AC 50/60 Hz and 600 V DC. The 2 kA limited short-time rating at both 0.5 s and 1 s confirms this is a switch disconnector, not a breaker — it must be upstream-protected by a circuit breaker or fuse. ## Integrated auxiliary release and contacts This variant ships with a shunt trip (STL) release rated for 110–127 V DC and AC 50/60 Hz, plus two built-in HQ auxiliary switches providing 2 CO contacts. The HQ designation indicates high mechanical endurance, matching the 15,000-cycle latching endurance. No undervoltage release is fitted, and no communication module. If remote status feedback beyond the two auxiliary contacts is needed, plan for an external I/O block. The motor drive option is listed as available, so a remote motor operator can be added later without replacing the disconnect. ## Mechanical fit and environmental limits Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth (–). The 101.6 mm width (4 inches) is standard for a 4-pole MCCB-form-factor device on a 160 A frame — it occupies the same footprint as a 4-pole 3VA1 breaker. Maximum power loss is 38 W, which should be factored into enclosure thermal calculations if multiple units are ganged.","metaTitle":"Siemens 3VA1163-1AA42-0JC0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0JC0 switch disconnector, 63 A rated continuous current, 4-pole, IEC frame 160, with shunt trip (STL) 110-127 V DC/AC and 2 HQ auxiliary switches.
