Section 6 Fuse Combination Units Loadswitch Range Fuse Combination Units (16-800A)
Overview Key Features 80kA short-circuit capacity Housed or skeleton versions Integral cable spreading facility with choice of position IP rated switch disconnectors Switch disconnectors in sheet steel enclosures Benefits Ease of installation Accepts large cables Rated for continuous full-rated load Compliance Fuse switches EN 60947-3 The Dorman Smith Loadswitch fuse combination range includes skeleton switches, housed switches and switch disconnectors. All Loadswitch fuse combination units exceed EN 60947-3 requirements and amply meet specifications for full uninterrupted duty to ensure that switches will maintain the maximum rated load indefinitely. Given their utilisation category of AC23A and a short-circuit capacity of 80kA, Loadswitch fuse combination devices provide complete confidence when installed in any resistive or inductive load application. Housed switches are supplied in sheet steel boxes with integral cable spreading space that can be positioned above or below the switch to suit ease of installation. The switch disconnector units are supplied in either IP65 insulated enclosures or sheet steel boxes. The robust steel enclosures are finished in light grey RAL 7035 epoxy powder coating and have doors that open 180 for ease of access. Padlocking is arranged to be off as standard and up to three padlocks can be attached with ease. 4
