Euro-Power

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.
