TELE Controls Inc. Protection Relays & Systems G4CM690V16ATL20

The G4CM690V16ATL20 is a multifunction power factor monitoring relay for 1- or 3-phase mains, designed to monitor inductive and capacitive loads with integrated PTC temperature sensing. It has two potential-free changeover contacts rated at 250V AC, switching up to 2000VA (8A) with a 20-million-operation mechanical life. Mounted on DIN rail TS 35, it measures 45mm wide. Supply voltage is selectable via power modules from 12 to 500V AC, with measuring ranges of 8A or 16A. Power factor thresholds (cosφ) are adjustable from 0.3 to 1, with start-up suppression (3s-180s) and tripping delay (1s-50s). It meets IEC 60664-1 overvoltage category III and rated surge voltage of 4kV, and operates from -25°C to +55°C.
