Leviton | Z-Max Lighting

This line of lighting control relay systems combines energy management features with extended service life and offers a solution for complying with the United States Department of Energy's ASHRAE 90.1-1999 standard. Z-Max's circuitry switches full capacity loads at the zero crossing point, providing true air-gap switching without leakage. It eliminates arc shower pitting at the contacts and extends the electrical life of the relay to 10,000,000 switching cycles. Read more
