        Description

        GIC Controls MG73BQ 3 Phase 4 Wire or Single Phase Voltage Monitoring Relay With DPDT Contacts, Undervoltage, Selectable Overvoltage, 3 x 120-240 VAC

        Relay control, on 3-phase networks :

        • Overvoltage between phases,
        • Undervoltage between phases
        • Overvoltage between phases and neutral,
        • Undervoltage between phases and neutral,
        • Loss of neutral
        • Multi-voltage Products
        • Controls its own supply voltage
        • True RMS measurement
        • LED status indication

        3-phase voltage controllers which monitor :

        • Undervoltage, adjustable from -20 to -2 % of Un
        • Overvoltage, adjustable from 2 to 20 % of Un
        • Measurements are taken between neautral and Phases for MG73BQ

        MG73BQ and between Phases and Neutral for the H3USN Faults are signalled via LEDs, distinguishing the origin of the fault (one LED for the upper threshold, one LED for the lower threshold). Set the selector switch to the 3-phase network voltage Un.

        The position of this selector switch is only taken into account when the unit is powered up. If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the voltage selected on energisation prior to the change of position. The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.

          • We’ve been working with Xtra for over a year now, and the experience has been nothing short of excellent. From the start, their team took the time to understand our store's profile and helped us build the perfect product assortment. Orders arrive quickly, the packaging is retail-ready, and our customers love the quality. It’s rare to find a supplier that combines efficiency with such a personal touch.

            5/5 Sophie, Owner (NL)

          • Xtra feels less like a supplier and more like a partner. We appreciate how easy it is to reorder, and how well the product photos and descriptions are made for online use, a huge help for our webstore. Their advice on bestsellers and seasonal trends has helped us improve our sell-through rate significantly. Highly recommended for any pet retailer looking for quality and consistency.

            5/5 Marco, E-commerce Manager (DE)

          • As a grooming salon, we don’t carry a massive inventory, so having a reliable supplier like Xtra is a game changer. We love that we can order small volumes and still get fast delivery and great service. are a big hit with our clients. Plus, their B2B portal is super intuitive and saves us time every week.
