Product details

It carries no overload or short-circuit protection — it is a pure disconnect, sized for isolating a load circuit under load or no-load conditions.

The 4-pole design (3 poles + switched neutral) makes it suitable for three-phase systems where the neutral needs isolation. Front terminals accept busbar connection for the main circuit, which keeps wiring tidy in a distribution panel.

Mounts in a standard MCCB cutout — 70 mm depth, 101.6 mm width, 130 mm height. The front terminals and busbar connection mean the busbars run across the front, not the rear, so plan the busbar routing accordingly. The two auxiliary switches (HP) are pre-installed and wired; they provide status feedback without needing a separate auxiliary contact block. Optional motor drive available for remote operation.

Frequently asked questions

What is the current rating and does it derate with temperature?

Rated 63 A continuous, and it holds that rating flat from 40 °C all the way to 70 °C. No derating needed for warm enclosures within that range.

Where can I buy 3VA1163-1AA42-0AB0 and get current pricing?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial offer.

Does this part include overload or short-circuit protection?

No. It is a switch disconnector only — no overload release, no short-circuit protection. It isolates the load circuit but does not protect it. Overcurrent protection must be provided upstream.
