ABB Phase Protection Device CM-PFS

Phase sequence relay – Phase monitoring relay 200…500V CM-PFS.S – ABB – 1SVR730824R9300 – 4016779851947: Phase sequence relay CM-PFS.S Design of the electrical connection screw connection, rated control supply voltage Us at AC 50 Hz 200 … 500V, rated control supply voltage Us at AC 60 Hz 200 … 500V, type of voltage for actuation AC, phase sequence monitoring function, phase failure detection function, voltage measuring range 200 . .. 500V, Min. adjustable response delay time 0.5s, Max. permissible response delay time 0.5s, Min. adjustable off-delay time 0s, Max. permissible off-delay time 0s, Number of contacts as opener 0, Number of contacts as closer 0, Number of contacts as Changeover contact 2, width 22.5 mm, height 85.6 mm, depth 103.7 mm. With the three-phase monitoring relay CM series, a reliable and continuous monitoring of a three-phase network, the trouble-free and economical operation of machines and systems can be guaranteed. That is why the three-phase monitoring relays of the CM series monitor the phase voltages, the phase sequence, the phase asymmetry, the presence of all phases and the neutral conductor as required.
