Countdown timer for lights and fans

The Maestro MA-T51MN-WH is a surface-mount countdown timer switch that controls lights and high-efficiency exhaust fans.

Suits bathrooms, closets and low-traffic rooms

Ideal for automatically shutting off lighting or ventilation after a set period in bathrooms, closets, attics, basements and garages. Not suited for installations without a neutral wire or for loads exceeding the rated LED or incandescent limits.

Handles up to 150 watts of LED lighting and 600 watts of incandescent, halogen or low-voltage lighting, plus 3-amp high-efficiency exhaust fans at 120 volts. Exceeding these limits will cause improper operation.
