Rockwill Electric strives to bring our customers the latest technology and competitive pricing and best service for distribution automatic.
The RCW series automatic circuit reclosers can use on overhead distribution lines as well as distribution substation applications for all voltage classes 11kV up to 38kV at 50/60HZ power system.and its rated current can reach 1250A.
The RCW series automatic circuit reclosers integrates the functions of control, protection, measurement,communication,fault detection,on-line monitoring of closing or opening.
With optional classes for rated current range:
For 15kV, with 630A, 20kA Breaking capacity. 800A, 20kA capacity, and 1250A, 20kA.
For 27kV, with 630A, 20kA Breaking capacity. 800A, 16kA capacity, and 1250A, 25kA.
For 38kV, with 800A, 12.5kA,. and 1250A, .20kA only.
With optional classes for installation styles:
Single phase, vacuum recloser.
Three phase, vacuum recloser.
With optional relay protection curves for user choice:
+with Instantaneous over current protection, definite time over current protection and over current protection, over current three-stage current protection, low voltage component block, composite voltage component block or direction component block is available for each section;
