Mini Secondary Relay Pack

The MSP20 secondary relay pack switches lighting loads on and off. Although plenum rated, the elongated mounting nipple allows for the MSP20 to be mounted either directly through a ½ inch knockout in a junction box or to be located inside an adjacent box for specific local code requirements.

The MSP20 is commonly used in multi-circuit control applications in combination with one or more MP20 units.
