PE Cell Daylight Switch Plug-in Cell, M-240, NEMA base 3-Pin, 1800VA, 185V-305V, Brown High Impact Noryl Housing with UV Inhibited Acrylic Integral Windowwith Surge Protection

Features:
• The M Series features a ceramic substrate forms the base for the CdS. Visible on the surface of this substrate is a complicated electrode pattern with cold-welded cell terminal connections.
• This design is employed to prevent changes in cell resistivity from causing oxidization which will in turn contribute to photo-control drift.
• The entire cell, including the terminal post connections, is then coated with a non discolouring, UV resistant clear layer.
• This organic-based, semiconductor compatible coating provides additional protection from humidity, condensation and airborne contaminants
• The unit is also fitted with a metal oxide resistor (MOV) designed to effectively clamp voltage surges that may otherwise damage the unit
