It provides load-break isolation for a 690 V AC or 600 V DC circuit, with an undervoltage release (UVR) coil rated 208-230 V AC 50/60 Hz that trips the switch on loss of control voltage. The UVR is wired in series with an emergency-stop or guard-door contact — when that circuit opens, the disconnector opens instantly, isolating downstream loads. The HQ aux switches are rated for high mechanical endurance and share the same 15 000-cycle mechanical life as the main switch. No overload or short-circuit protection is built in; this part is a pure disconnector, not a circuit breaker. ## Flat thermal curve simplifies panel sizing That means the 63 A nameplate holds even in a hot enclosure near a drive or transformer. Busbar connection on the front terminals keeps wiring clean and reduces cable congestion in the panel.","metaTitle":"Siemens 3VA1163-1AA42-0DC0 SENTRON Switch Disconnector, 63A,","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0DC0 switch disconnector, 63 A, 4-pole, IEC frame 160.
