DOE 2016 Energy Efficient Three Phase and Single Phase Watchdog

Class 7400 / Refer to Catalog 7400CT0601

DOE 2016 Energy Efficient Watchdog Three Phase and Single Phase

Watchdog transformers, by design, reduce energy consumption at loads greater than 50% loading, giving fewer BTUs/hour at those loading levels. The life expectancy is greater than that of 150°C rise General Purpose units.

Aluminum or copper windings
Two temperature rise options: 115°C rise on 220°C insulation systems (15% continuous emergency overload capacity); 80°C rise on 220°C insulation systems (30% continuous emergency overload capacity)
