This is the Perko 9611DP, a main battery disconnect switch without a key lock. It has a polycarbonate body and brass terminals on 3/8 inch studs, and it is ignition protected. The body is 4-3/4 inches across and 1-7/8 inches deep, made for marine systems from 6 to 50 volts. Capacity is 315 A continuous, with 450 A allowed for 5 minutes.
Our take
The 315 A continuous rating, with 450 A allowed for 5 minutes, is the figure to match against your cable and loads. The body is 4-3/4 inches across and 1-7/8 deep, so measure the mounting spot first. There is no key lock on this version.
From our buying guide
Perko says its selector switches can be switched between 1, ALL and 2 with the engine running, and that they let you put batteries in parallel for emergency starting. Battle Born advises against that connection with its LiFePO4 batteries.
Check before you buy:
- Its continuous and 5-minute ratings suit your system. Perko rates its medium-duty 8501 at 250 A continuous.
- It has an alternator field disconnect if you need one. Perko says its AFD models protect non-unitized alternators if the switch is turned OFF with the engine running.
- If it's going in a gasoline engine space, the maker lists it as ignition protected.
