The OP-DFST is a digital fused-spur time switch. The timer is suitable for patress box mounting. The 7 day programming logic controls a mains-linked switch, with a resistive rating of 13 amperes. There is an inbuilt re-chargeable cell to keep the timer running in the event of a loss of mains power. The output can be disconnected by an integrated double-pole isolator switch; the load is protected by a replaceable BS1362 13 Ampere cartridge fuse, within a removeable caddy.
