Phase sequence relay - Phase monitoring relay 208...440V CM-PFE

Phase sequence relay - Phase monitoring relay 208...440V CM-PFE – ABB – 1SVR550824R9100 – 4013614348044: Phase sequence relay CM-PFE Design of the electrical connection screw connection, rated control supply voltage Us at AC 50 Hz 208 ... 440V, rated control supply voltage Us at AC 60 Hz 208 ... 440V, type of voltage for actuation AC, phase sequence monitoring function, phase failure detection function, voltage measuring range 208 ... 440V, Min. adjustable response delay time 0.5s, Max. permissible response delay time 0.5s, Min. adjustable off-delay time 0.5s, Max Contacts as changeover contact 1, width 22.5mm, height 78mm, depth 78.5mm. With the three-phase monitoring relay CM series, reliable and continuous monitoring of a three-phase network, 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.
