snow switch EUR-5A

Automatic Snow/Ice Melting Control Panel for Electric & Hydronic Applications

The EUR-5A brings the performance, economy and energy efficiency of the industry leading APS–3B to a wide range of commercial snow melting applications requiring electrical panel location. A rich assortment of features optimize EUR-5A performance for its intended applications and environment. The EUR-5A interfaces multiple sensors from the CIT–1, GIT–1, SIT–6E family for flexibility in a wide range of pavement, gutter and downspout deicing applications. This feature is essential for large systems employing common heater switching.
