Description
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 it’s 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.
The RCW series vacuum recloser is mainly combined with integration
terminal, current transformer, permanent magnetic actuator and it’s
recloser controller.
Features
Optional grades available in rated current range.
With optional relay protection and logic for user selection.
With optional communication protocols and I/O ports for users to choose.
PC software for controller testing, setup, programming, updates.
