GIC MG73BH Voltage Monitoring delivers precise supervision on 240 VAC single or three-phase, 4-wire supplies at 50/60 Hz with just 4 VA consumption. It detects phase loss and manages 10% asymmetry while guarding against under-voltage from 55%โ95% and over-voltage from 105%โ125%, stabilized by a 7 V (ยฑ2 V) hysteresis. A selectable ON delay 0.5โ15 s and fixed 5 s trip time balance sensitivity with nuisance-trip reduction. Two C/O relay outputs (5 A @ 250 VAC/28 VDC, resistive) integrate cleanly into alarms or control circuits. The compact 36ร60ร90 mm module mounts on base or DIN-rail, runs from โ15ยฐC to +55ยฐC at 95% RH, and uses a flame-retardant UL 94-V0 enclosure with IP20/IP40 protection to ensure durable, safe operation.
In panels for motors, HVAC units, elevators, and pump systems, the MG73BH helps prevent equipment damage by reacting quickly to abnormal voltages. Adjustable delays and defined hysteresis reduce false trips during starts or brief sags, while compact size and DIN-rail mounting simplify retrofits in crowded enclosures. For Indian plants and commercial sites seeking uptime, this Voltage Monitoring approach improves asset life, reduces maintenance calls, and supports predictable operations with straightforward wiring and clear set-and-forget protection.
