Product Overview

Product Description

The water level control box is a simple, cost effective control for applications when the water level is variable. The Munro water level control provides pilot duty operation when thermal overload protection is present, for example, submersible water feature pumps or dewatering pumps. Used any place power can be interrupted, this control transforms all outbound voltage to a low, safe, 24v. Low external voltage is especially important when external sensors or switches are used, such as the float switch included with this control box.

This flexible, easy-to-install pump start relay provides “pilot-duty” operation for all electrically driven pump equipment. No need to wonder which relay to use, the Munro StartBox has a 40 amp relay to work equally well with single phase 3/4 hp to 5 hp.* For use with controllers with a .36 amp signal or stronger.
