GPC-1015B-R is a low voltage disconnect.
It disconnects attached load if the battery voltage drops below predefined threshold.
It reconnects the load when the battery is recharged.
For install instructions and details, please go to
Ten threshold options set by rotary selector
For 12V battery: 2, 9.3V; 3, 9.7V; 4, 10.1V; 5, 10.5V; 6, 10.9V; 7, 11.3V; 8, 11.7V; 9, 12.1V
For 24V battery: 2, 18.6V; 3, 19.4V; 4, 20.2V; 5, 21.0V; 6, 21.8V; 7, 22.6V; 8, 23.4V; 9, 24.2V
When selector=0, OFF: Disconnect power from the load. (When rotated to 2~9, the unit will stay off until reconnect threshold is reached.)
When selector=1, ON: Connect power to the load if no pending fault. (When rotated to 2~9, the switch will stay on until disconnect threshold is reached.)
Recessed selector. See GPC-1015B-F for waterproof flushed selector option.
