Power
Select Euro series fixed resistors for applications
requiring wattage ratings from 72 to 1000 watts.
Suitable for rugged applications, Euro-Power resistors are spot welded producing stronger mechanical 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 terminals suitable for soldering or sturdy bolt connection.
Mounting brackets not included with resistors.
