It is designed for applications where you need a manual disconnect with visible isolation, not a circuit breaker — think load-break switch duty ahead of a VFD or as a panel main isolator where the upstream device handles fault clearing.
Rated 690 V AC and 500 V DC, so it handles standard 400 V three-phase systems with headroom and can switch DC loads up to 500 V — useful for battery banks or DC bus isolation. No auxiliary contacts are included, so if you need status feedback to a PLC, you'll add a separate auxiliary switch block. For daily switching in a production line, that's years of service; for frequent cycling (multiple times per shift), consider a contactor instead. The IP40 front protection means it's suitable for clean indoor panel environments; no washdown rating here.
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB cutout. Front terminal connections with clamp-type terminals accept lug or cable. The design accepts an optional motor drive for remote switching, and the UVR coil draw is included in the loss figure.
