ASW-A805 — Manual Battery Switches — 250 A Working Current, 1,000 A Cranking Current, 12-24 V DC Operating Voltage

BATTERY SWITCH / BATTERY DISCONNECT SWITCH / MANUAL POWER ISOLATION

ASW-A805 250A battery disconnect switch

DAIERTEK ASW-A805 is a manual battery disconnect switch for 12-24 V DC systems, with a 250 A working current rating and a 1,000 A cranking current rating. It uses a manual T-handle, two cable terminals and a round mounting flange. The two cable terminals connect the incoming battery feed and outgoing circuit, while the flange provides the panel attachment interface. Two mounting holes spaced 40 mm apart define the fixing interface. The operating temperature range is -40 to +80 deg C. The switch provides manual battery isolation for vehicle servicing and storage and is supplied for aftermarket wholesalers, replacement-parts distributors and vehicle equipment programs.

Product Details

01 250 A working current and 1000 A cranking current
The switch is specified for 250 A working current and 1,000 A cranking current in 12-24 V DC battery systems. The cranking current rating is separate from the working current rating.
02 Two mounting holes on 40 mm centres
The two cable terminals connect the incoming battery feed and outgoing circuit, while the flange provides the panel attachment interface. Two mounting holes on 40 mm centres provide the fixing interface.
03 Operating temperature range
The operating temperature range is -40 to +80 deg C. The manual T-handle provides direct control of the battery connection, with the round flange supporting panel installation.
