TELE Controls Inc. Protection Relays & Systems G2CU400V10AL10

The G2CU400V10AL10 is a power factor monitor for single- or three-phase mains, providing underload detection with optional fault latch and disconnected load recognition. It mounts on a DIN rail (TS 35, EN 60715) with a width of 22.5 mm and an IP40-rated plastic housing. Operates on 12-400 V a.c. or 24 V d.c., measuring input voltage up to 415 V a.c. and current from 0.5 to 10 A. Monitors power factor from 0.1 to 1.0 with fixed hysteresis. Features one potential-free change-over contact rated 250 V a.c., 750 VA (3 A), with mechanical life of 20 × 10⁶ operations and electrical life of 2 × 10⁵ operations at 1000 VA resistive load. Ambient temperature range is -25 to +55 °C, overvoltage category III, surge voltage 4 kV.
