CZ Bypass Switches
125A to 630A
Bypass Switches are meant for special application and help to maintain continuity of power supply to the load by simply ‘bypassing’ UPS or Servo stabilizer. Removal of the UPS or Servo, for maintenance or repair is safe, as it is isolated from both input and output sides in the ‘bypass’ mode.
Time-Saving Convenient solution
No hassle of operating multiple devices for safe and positive isolation on both sides of Servo/UPS
Suitable for Aluminum Termination
Entire range is suitable for Aluminum cable/link termination as per the size prescribed by the standards
Mounting flexibility
Suitable for mounting in horizontal as well as vertical orientation. Also, the shaft is ‘cut-able’ and can be adjusted to suit different panel depth requirements.
Phase Barriers
Easy to fit and long phase barriers for complete isolation between phases
Safety interlock and padlocking
Door interlock is provided in ON position with defeat feature Also, Bypass Switch can be padlocked in OFF position; upto 3 padlocks can be fitted
Finger proof protection (IP30)
Terminal Shrouds provide protection against accidental contact with live terminals. As it is swivellable, there is no need to remove during termination/inspection
