The M Series photocontrols are engineered to meet the demanding needs of utility street lighting control. A heavy-duty thermal bi-metal switch in the M series produces a minimum 30-45 second time delay, eliminating unwanted off/on operations that could be caused by lightning, car headlights or other sudden changes in the ambient light. This feature makes the M Series well suited for areas with high lightning activity.


• Up to 360 Joule Surge Protection
• Heavy-Duty Thermal Bi-Metal Switch
