Its two-channel architecture means it can monitor a three-phase supply for phase sequence and loss on one channel while tracking overvoltage on the other — or handle two independent single-phase feeds. The relay output is a changeover contact rated for the usual control-circuit loads (pilot duty, contactor coils, PLC inputs). No special isolation transformer needed; the relay draws its own supply from the monitored voltage, so wiring is straight through the terminals.
The estimated lead time is 4 to 6 weeks. For current availability and pricing, submit an RFQ — we confirm both at quote time.
This relay is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
ABB's CM-ESS.2P family includes several voltage monitoring relays with the same two-channel DIN-rail footprint. The key differentiator among them is the voltage range and the specific monitored parameters (overvoltage, undervoltage, phase sequence, asymmetry). No pin-compatible direct substitute exists without verifying the application voltage and trip thresholds.
