Switch disconnector for load-break and isolation duty
It provides visible isolation and load-break switching without overload or short-circuit protection — that's the role of the upstream MCCB or fuse. The IP40 front protection keeps dust and tools out of the enclosure cutout, but the back and sides rely on the panel's own IP rating.
Shunt trip and auxiliary contact complement
The front-terminal busbar connection keeps wiring clean on a DIN-rail or mounting-plate layout; the 101.6 mm width and 70 mm depth fit standard 160 A frame cutouts.
Rated insulation voltage Ui is 800 V, and maximum operational voltage is 690 V AC (50/60 Hz) or 600 V DC — so it's suitable for 400/480 VAC industrial panels and 600 VDC battery or solar circuits. The rated short-time withstand (2 kA for 1 s or 0.5 s) covers the conditional short-circuit rating when backed by an upstream protective device.
