Description
Product Summary
The Little Giant ACS-2 (item 599123) is an in-pan condensate overflow safety switch that sits in the auxiliary or primary drain pan of an air handler, furnace or evaporator coil. When water in the pan rises to the trip level, the switch breaks the control circuit and shuts down the equipment before the pan can overflow and damage ceilings, floors or walls.
It is rated for 48V AC/DC at up to 5 amps, so it works on standard 24V thermostat control circuits, and it comes with 72 in lead wires.
Before you order, choose the lead length that reaches from the pan to your wiring connection point. If you are not sure which switch you need, call us at 1.888.509.3391 and we will confirm it for you.
