CM-MPS.72S 1SVR430884R3300  Three-phase monitoring

The three-phase monitoring relays CM-MPS.x1 monitor the phase parameters phase sequence, phase failure, over- and
undervoltage as well as phase unbalance.
All devices are available with two different terminal versions.
You can choose between the proven screw connection technology (double-chamber cage connection terminals)
and the completely tool-free Easy Connect Technology (push-in terminals)

Monitoring of three-phase mains for phase sequence (can be switched off), phase failure, over- and undervoltage as
well as phase unbalance
• TRMS measuring principle
• Interrupted neutral monitoring (CM-MPS.11)
• CM-MPS.11 can also be used to monitor single-phase mains
• Threshold values for over- and undervoltage as well as phase unbalance are adjustable as absolute values
• Tripping delay Tv can be adjusted or switched off by means of a logarithmic scale (0 s; 0.1-30 s)
• ON-delayed or OFF-delayed tripping delay selectable
• Powered by the measuring circuit
• Precise adjustment by front-face operating controls
• Screw connection technology or Easy Connect Technology available
• Housing material for highest fire protection classification UL 94 V-0
• Tool-free mounting on DIN rail as well as demounting
• 2 c/o (SPDT) contacts
• 22.5 mm (0.89 in) width
• 3 LEDs for the indication of operational states

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 DIN ISO
2380-1 Form A 0.8 x 4 mm (0.0315 x 0.157 in), DIN ISO 8764-1 PZ1 ø 4.5 mm (0.177 in))
• 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
• One screw for opening and closing of both cages
• Pozidrive screws for pan- or crosshead screwdrivers according to DIN ISO 2380-1 Form A 0.8 x 4 mm (0.0315 x
0.157 in), DIN ISO 8764-1 PZ1 ø 4.5 mm (0.177 in)
