Block USA's cross reference puts it on 350 to 400 HP drives at 480 V. It is UL 508 Listed and cULus marked, open frame (IP00), with copper windings, class H insulation and flat copper terminals. Applied Control is the Block manufacturers representative. Send the catalog number, or the drive HP, voltage and impedance you need, and we send back a quote.\u003c\/p\u003e\u003cp style=\"margin:18px 0;\"\u003e\u003ca

A 5% reactor cuts input current harmonics further and gives more protection when the supply is stiff or has capacitor switching upstream. On the output side, a reactor slows voltage rise at the motor on longer lead runs. Send the drive model and motor lead length and we will size it with you.
