Description

The Rule-A-Matic Plus 40FA is a high capacity marine bilge pump float switch designed for pumps drawing up to 20 amps. It automatically activates a bilge pump when water reaches 50 mm and deactivates when water falls to 19 mm.

This model is suitable for 12V, 24V and 32V DC bilge pump systems and includes a protective impact-resistant cover, debris guard, and in-line fuse holder. The 40FA should not be confused with the Rule 40A, which does not include the in-line fuse holder.

What is the Rule 40FA used for?

The Rule 40FA is used to automatically control a bilge pump by sensing rising water levels in the bilge. It can also be used to operate compatible high water alarm systems.

Is the Rule 40FA compatible with my bilge pump?

The Rule-A-Matic Plus 40FA is compatible with DC bilge pump systems operating at 12V, 24V or 32V, provided the pump draws 20 amps or less.
