Push-in terminals
–– Tool-free connection of rigid and flexible wires with
wire end ferrule
–– Easy connection of flexible wires without wire end
ferrule by opening the terminals
–– No retightening necessary
–– One operation lever for opening both connection
terminals
–– For triggering the lever and disconnecting of wires
you can use the same tool (Screwdriver according to

–– Constant spring force on terminal point independent
of the applied wire type, wire size or ambient
conditions (e. g. vibrations or temperature changes)
–– Opening for testing the electrical contacting
–– Gas-tight
Double-chamber cage connection terminals
–– Terminal spaces for different wire sizes:

Application
The CM-PFS is used to monitor three-phase mains for incorrect phase sequence and phase failure.
Operating mode
The three-phase main to be monitored is connected to terminals L1, L2, L3 in accordance to the wiring diagram.
The device operates according to the closed-circuit principle g – incorrect phase sequence or phase failure: relays deenergize.
The signalling of status indication is made by means of the front-face LEDs.
Function diagram
Phase sequence and phase failure monitoring
If all phases are present with the correct phase sequence, the output relays energize after the start-up delay ts is complete.
If a phase failure or a phase sequence error occurs, the output relays de-energize instantaneously.
The LED R is on when output relays are energized.
In case of motors which continue running with only two phases, the CM-PFS detects phase failure if the reverse fed voltage
is less than 60% of the originally applied voltage.
