Categories of use The categories of use applicable for each unit are indicated
on the identification label
• AC-51 Non-inductive or low inductance loads, furnace
resistances
(Resistive load with low temperature coefficient).
• AC-55b Switching of incandescent lamps, for units
≤
100 A
(Short wave infrared elements, SWIR).
• AC-56a Switching of transformers
(Transformer primaries and high temperature
coefficient resistive loads).
Options must be fitted to 7300A units in order to comply
with certain categories of use.
Connections Independent of phase rotation order
Load configuration Star with or without neutral, open or closed delta.
Configuration on order.
