| Utilizing patented relay contact protection the SP20 347 secondary relay pack switches lighting loads on and off. Although plenum rated, the elongated mounting nipple allows for the SP20 347 to be mounted either directly through a 1/2 inch knockout in a junction box, or to be located inside an adjacent box for specific local code requirements. The SP20 347 is commonly used in multi-circuit control applications in combination with one or more PP20 347 units. |
