| Design Of The Product | For motor protection |
It's part of the SIRIUS product family, built for motor protection with phase failure detection onboard — no ground fault detection on this variant. Rated operating voltage spans 20 to 690 V. Terminals are screw-type, accepting 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²).
Dimensions are 55 mm wide, 140 mm high, 149 mm deep. That 149 mm depth is the body depth — factor it into enclosure depth clearance, especially if you're running wires behind the rail.
The breaking capacity is 50 kA at 400 V rated value.
Yes, it has phase failure detection. It does not include ground fault detection.
It mounts via screw and snap-on onto 35 mm standard mounting rail per DIN EN 60715, in any mounting position.
Screw terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire.
