Wirewound Tubular HIgh Power Euro-Power Wirewound 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 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.
