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 Phase Barriers
No hassle of operating multiple devices for safe and Easy to fit and long phase barriers for
positive isolation on both sides of Servo/UPS complete isolation between phases
Suitable for Aluminum Termination Safety interlock and padlocking
Entire range is suitable for Aluminum cable/link Door interlock is provided in ON position with defeat
termination as per the size prescribed by the feature Also, Bypass Switch can be padlocked in
standards OFF position; upto 3 padlocks can be fitted
Mounting flexibility Finger proof protection (IP30)
Suitable for mounting in horizontal as well as Terminal Shrouds provide protection against
vertical orientation. Also, the shaft is ‘cut-able’ and accidental contact with live terminals.
can be adjusted to suit different panel depth As it is swivellable, there is no need to remove
requirements. during termination/inspection
