The main circuit connects via busbar front terminals. This part is a pure switch disconnector — it provides no overload or short-circuit protection. The 2 kA short-time withstand rating (1 s and 0.5 s) defines its capability to carry fault current until an upstream protective device clears it, not to interrupt a fault itself. That makes it a load-break isolator for a panel's main incoming supply or a branch feeder where protection is handled separately. Two HQ auxiliary contacts report the main contact position back to the PLC or status lamp. No undervoltage release is fitted, so a loss of control power will not automatically open the disconnector. Panel footprint: 130 mm height, 101.6 mm width, 70 mm depth. The front terminal arrangement accepts busbar connections for the main circuit, which simplifies panel wiring in a multi-feeder distribution assembly. Maximum power dissipation is 38 W — plan for that heat load in a sealed enclosure with restricted natural convection.","metaTitle":"Siemens SENTRON 3VA1163-1AA42-0KC0 Switch Disconnector, 63A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0KC0 IEC switch disconnector, 63 A rated continuous current, 4 poles, shunt trip 220-250 V DC / 208-277 V AC.
