Masterlink Stainless Steel Enclosed Local Switch-Disconnectors
IP65 16A-80A, 3 or 4 Pole
A new range of stainless steel enclosed switch-disconnectors for use where hygiene and good protection against corrosion are necessary.

This range is ideally suited to use in hospitals; schools; brewing; pharmaceutical plants and food processing such as the dairy industry.

Robust IP65 enclosures house a choice of 3 or 4 pole switch units from 16A to 80A. Switches are suitable for on load switching of general distribution A.C. power circuits and frequent duty motor isolation providing excellent AC22A and AC23A ratings.

External fixing feet are fitted which do not encroach on the integrity of the enclosure. Enclosures are fitted with three plugged, conduit entries at the bottom: 16 – 63A = 20mm, 80A = 25mm.

Device handles are padlockable in the ‘OFF’ position with up to three padlocks.

Switch units comply with BS EN 60947. Positive contact indication is provided.
