Adjustability full value. Wattage proportional this adjusted resistance value. Material Coating: Lead free vitreous enamel. Core: Tubular ceramic.
Terminals: Solder coated radial lug. RoHS solder composition 3.5% 0.5% Adjustable terminal: Nickel plated steel. (Screwdriver type adjustable supplied standard. Other types, including silver contact units, available.) Derating: Linearly from 100% +25°C +350°C. Electrical Tolerance: ±10% Power rating: Based 25°C free rating. stated wattage rating applies only when entire resistance circuit. Setting intermediate point reduces wattage rating approximately same proportion. Example: half resistance, wattage reduced approximately one-half. Overload: times rated wattage seconds. Temperature coefficient: ±260 ppm/°C Dielectric withstanding voltage: 1000 VAC: watt rating. 3000 VAC: watt rating (measured from terminal mounting bracket) calculate max. amps: formula P/R. page mounting hardware
