The SENTRON 3VA1163-1AA36-0AB0 is a 3-pole switch disconnector built in MCCB (moulded-case circuit breaker) design — meaning it shares the frame, footprint, and terminal layout of a 160 A frame MCCB but is configured purely for isolation and switching duty, not overcurrent protection. Rated 63 A continuous at 690 V AC or 500 V DC, it is intended for use as a main disconnect or load-break switch in industrial control panels and distribution boards where a visible air gap and positive break indication are required by code. That simplifies panel design: the same 63 A bus and conductor sizing works whether the cabinet sits in a conditioned electrical room or near a hot process line.
The DC rating at 500 V suits battery banks or DC bus isolation. Power dissipation is 38 W maximum at rated current. Account for this in the thermal budget for an IP40 front-panel installation. Mechanical service life is 15 000 operating cycles typical. That is a maintenance disconnect duty cycle — not a daily switching device for motor starts. For frequent operation (e.g. multiple cycles per shift), consider a contactor-based solution instead.
Front terminal connection for the main circuit, accepting clamp terminals. The 76.2 mm width fits standard DIN-rail mounting. Depth is 70 mm. No separate auxiliary contact block to purchase and mount. There is no undervoltage release or shunt trip fitted — this is a plain disconnect, not a remote-tripping device.
