  • RCM470LY

    Ground fault monitor for grounded and high-resistance grounded AC systems

    The RCM470LY monitors for ground fault current in grounded and high-resistance grounded AC systems, both single-phase and three-phase. The RCM470LY features a steplessly adjustable setpoint from either 6 mA...600 mA or 10 mA...10 A. Display features include power and alarm LEDS, as well as an LED bar graph indicating how close the system is to the alarm value. An adjustable time delay of 0...10 s is available.

    The device may be set to latching or non-latching operation, and features one DPDT alarm relay which may be set to normally energized or normally de-energized operation. An external BENDER current transformer is required for operation.

    Digital ground fault monitor for grounded and high-resistance grounded AC systems

    The RCM420 monitors for ground fault current in grounded and high-resistance grounded AC systems, both single-phase and three-phase. The RCM420 reads a true RMS value, and displays the read ground fault current in real-time on the built-in digital display. The RCM420 features a steplessly adjustable setpoint from 10 mA to 10 A. Along with the main alarm value, a prewarning alarm, set as a percentage of the main alarm value, may be set.

    All settings for the device are changed via the device's onboard, easy-to-use menu. Three separate time delays may be utilized - a trip delay (0 to 10 s), a startup delay (0 to 10 s), and a delay on release (0 to 99 s). Two SPDT alarm relays may be set to normally energized or normally de-energized operation, and may be set to latching or non-latching operation. An external BENDER current transformer is required for operation.

  • RCMS460

    Multi-channel, digital ground fault monitor for grounded and high-resistance grounded AC/DC systems

    This devices meets or exceeds compliance with the upcoming 2014 NEC 250.167(B) code for ground fault detection on grounded DC systems.

    The RCMS460 monitors for ground faults in grounded and high-resistance grounded AC/DC systems, both single- and three-phase. The RCMS460 is capable of monitoring up to twelve separate systems or branches from one device. Each channel may be set to a separate alarm value. AC circuits may be set to an alarm value of 6 mA to 20 A. DC and mixed AC/DC circuits may be set to an alarm value of 10 mA to 10 A. One DPDT contact output for the device may be set to normally energized or normally de-energized operation, latching or non-latching.

    The detailed LCD display is capable of showing a detailed analysis of the system, including: a chart showing each channel's ground fault current in real-time; individual alarm messages for each channel; and an easy-to-use menu for settings.

    The RCMS460 features three separate time delays - a response delay (0 - 999 s), a startup delay (0 - 99 s), and a delay on release (0 - 999 s). Additional features include a harmonics analysis chart, selectable filtering options, and compatibility with BENDER's gateway devices for connecting to Ethernet and Modbus/TCP networks.

  • RCMS490

    Multi-channel, digital ground fault monitor for grounded and high-resistance grounded AC/DC systems

    This devices meets or exceeds compliance with the upcoming 2014 NEC 250.167(B) code for ground fault detection on grounded DC systems.

    The RCMS490 monitors for ground faults in grounded and high-resistance grounded AC/DC systems, both single- and three-phase. The RCMS460 is capable of monitoring up to twelve separate systems or branches from one device. Each channel may be set to a separate alarm value. AC circuits may be set to an alarm value of 6 mA to 20 A. DC and mixed AC/DC circuits may be set to an alarm value of 10 mA to 10 A. One DPDT contact output for the device may be set to normally energized or normally de-energized operation, latching or non-latching. The RCMS490 also features 12 separate SPST relay outputs, one for each channel.

    The detailed LCD display is capable of showing a detailed analysis of the system, including: a chart showing each channel's ground fault current in real-time; individual alarm messages for each channel; and an easy-to-use menu for settings.

    The RCMS460 features three separate time delays - a response delay (0 - 999 s), a startup delay (0 - 99 s), and a delay on release (0 - 999 s). Additional features include a harmonics analysis chart, selectable filtering options, and compatibility with BENDER's gateway devices for connecting to Ethernet and Modbus/TCP networks.

    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.
