Switch disconnector for isolation and safety switching
The 690 V AC 50/60 Hz max operational voltage (Ue) and 800 V rated insulation voltage (Ui) suit it for 400 V line-to-line panels with headroom.
Rated continuous current Iu of 63 A means this switch disconnector carries 63 A indefinitely without exceeding temperature rise limits — sized for a 63 A feeder or a motor load drawing up to that current. The 15 000 latching-endurance cycles (mechanical) cover frequent manual switching in a maintenance disconnect role, though not daily production cycling. When supply voltage falls below about 70-80% of rated, the release trips the mechanism open. No leading contact on the UVR (: No), so the release does not anticipate the main pole closure — the switch must be manually reset after a voltage dip. The IP40 front protection means it's dust-protected but not washdown-rated; install inside a panel with a door. In a densely packed panel, that 38 W per unit adds to the thermal budget; allow ventilation or spacing around the 70 mm depth × 101.6 mm width × 130 mm height footprint.
Main circuit connection is busbar connection at the front terminals, so it's designed for horizontal busbar distribution in a panelboard or switchboard lineup. No auxiliary contacts are fitted (: Without), so there's no remote status feedback unless you add the optional auxiliary switch kit (product extension optional motor drive available per). The IP40 front face keeps tools and fingers out but doesn't seal against hose-down — keep it behind a panel door in washdown zones.
