1X Series Supervision relays

The 1X serie is comprised of an electromechanical voltage operated relay which is wired across the circuit being monitored. The relay may be ordered to operate in one of four (4) different application modes as described in the Technical Bulletin.
The relay is designed for flush mounting utilizing a single 25mm diameter mounting hole which also houses the large LED indicator. Electrical termination is made via four screw terminals on the rear of the case. This terminal block is of a plug in type with integrated retention screws further simplifying installation.

  • 1X30 Trip Circuit Supervision Relay

     The 1X30 relay is comprised of two electromechanical relays which are wired across the protection trip contact and the circuit breaker 52a and 52b pallet switches. This results in the alarm relay being normally energized provided the trip supply, the trip circuit and the circuit breaker coil are all healthy. Failure of the trip supply, the circuit under supervision or the CB coil will cause the alarm relay to be…

  • 1X50 CB Trip & Close Module

     The 1X50 Trip & Close Module has been designed to provide a cost effective & feature rich solution for the manual control & indication of CB status. The panel or rack mount configuration allows the compact 1X50 to be located on the protection panel adjacent to the overcurrent feeder relay. 22mm heavy duty push buttons are employed for the CB Trip & Close functions while two LED’s are employed for…
