It provides no overload or short-circuit protection — its job is safe isolation under load, not circuit protection. The built-in undervoltage release (UVR) operates on 120–127 V AC 50/60 Hz, so if control voltage drops, the disconnector opens automatically, preventing a motor from restarting unexpectedly after a sag. The unit measures 101.6 mm wide × 130 mm high × 70 mm deep. It uses a busbar connection for the main circuit, with front terminals — so it's designed for a fixed, screw-clamp busbar system, not plug-on DIN-rail. The latching endurance of 15 000 cycles is mechanical; for frequent switching, factor in the electrical endurance (not listed here, but typically lower under full load).","metaTitle":"Siemens 3VA1163-1AA42-0CH0 Switch Disconnector, 63 A, 4-Pole","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0CH0 switch disconnector, 63 A rated continuous current, 4-pole, with undervoltage release 120-127 V AC.
