Powr-Rib^® are designed to handle 700-1000 watts of power. Their construction consists of thick, heavy resistance alloy wound around porcelain ceramic core insulators supported by a metal mounting bar. The bar is slotted on each end to facilitate installation. Edgewound Powr-Rib^® provide low resistance at high current ratings, while Round Wire Powr-Rib^® provide higher resistance at lower current ratings. Clamp-type terminals on the Edgewound units permit a reliable connection that can be moved along the resistive element to obtain intermediate values. Tolerance: ±10%. Average Weight: 3 Lbs. 16.25" Long between mounting centers.
