    Ground fault monitor panel for marina shore power

    MarinaGuard series panels detect ground faults for shore power in marinas. Options are available for monitoring either main feeders or branch circuits. The MarinaGuard satisfies the new requirements in the 2011 National Electrical Code, article 555.3, "Ground-Fault Protection." All models may be set to 100 mA for feeder protection, and may be set lower if desired. Models for monitoring branch circuits may be steplessly adjustable down to 6 mA. All models feature a NEMA 4X rated enclosure, with test and reset buttons, power and alarm LEDs, and a strobe light on the top of the enclosure for clear indication if a fault has occured.

    All models support the optional "C" add-on, which adds wireless SMS / text messaging of alarms in the MarinaGuard panel. Messages may be sent to multiple technicians. Additionally, MG-S and MG-T models support connecting to BENDER's advanced communication system, to connect to Ethernet and Modbus/TCP networks for remote notification to master stations.

    Ground fault and ground continuity panel for universal voltages up to 600 VAC

    GFGC series panels provide an all-in-one solution for ground fault detection, ground continuity monitoring, and interruption in case of an alarm. Utilizing the latest in technology, the GFGC panels can detect both AC and DC ground fault currents down to 6 mA without the problems associated with high sensitivity nuisance tripping. The panel also verifies ground connection integrity over a widely adjustable range. A built-in unversal voltage selection allows use of the panel on common system voltages from 120 VAC to 600 VAC (see datasheet for available voltage options). Panels rated for 30 A, 60 A, and 100 A of load current are available.

    • All-in-one package for ground fault monitoring, ground connection integrity, open ground detection, and interruption of power
    • Universal voltage selection of common voltages from 120 VAC to 600 VAC
    • 6 mA ground fault trip level
    • Inverse time curve for interrupting circuit on a ground fault
    • Open ground detection
    • Adjustable ground integrity alarm point between 0.1 Ω to 100 Ω
    • NEMA 4/12 rated enclosure
    • External test and reset buttons
    • External LED indication for power and ground fault / ground continuity alarms
    • Internal real-time indications of ground fault current and ground integrity via digital displays
