Wirewounꢀ Series
Vitreous Enamel Power
Select Euro series fixed resistors for applications
requiring wattage ratings from 72 to 1000 watts.
Suitable for rugged applications, Euro-Power resis-
tors are spot welded producing stronger mechani-
cal and electrical connections. The vitreous enamel
coating was specifically developed and provides
protection against moisture and mechanical damage.
Euro-Power resistors are equipped with lug termi-
nals suitable for soldering or sturdy bolt connection.
Mounting brackets not included with resistors.

• Terminals suitable for soldering or bolt connection
• High wattage applications
• Rugged lead free virtreous enamel coating
• Flame resistant coating
• All-welded construction
• "Live" mounting option
