What is the Honeywell K4857RPWHI?

The Logic Plus™ Three Pole Fan Isolator provides a safe and simple method of isolating mechanical fan units and is particularly useful in bathrooms, toilets, storerooms and basements where there is little or no natural light. The fan isolator can be used as a double pole or triple pole isolator. In addition it includes a clear on/off indicator and the frontplate features a fan isolator symbol for easy circuit identification. In such an installation there is often a need for the lighting circuit to remain live to provide light and the fan unit is externally isolated so that routine maintenance and repairs can be carried out in complete safety.
