{"product_id":"block-lr3-48-5-8-line-reactor","title":"LR3 48-5\/8 Block Line Reactor, 8 A, 5% Impedance, 480 V, 3 to 5 HP","description":"\u003cp\u003eThe Block LR3 48-5\/8 is a 3 phase line reactor rated 8 A at 480 V with 5% impedance (4.6 mH per phase). Block USA's cross reference puts it on 3 to 5 HP drives at 480 V. It is UL 508 Listed and cULus marked, open frame (IP00), with copper windings and class F insulation. Applied Control is the Block manufacturers representative. Send the catalog number, or the drive HP, voltage and impedance you need, and the quote comes back the same business day.\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.
