RCMS series
The RCMS series monitors up to 12 channels on one unit (maximum 1080 in a system) for faults on grounded and high resistance grounded systems running on either Type A or Type B (according to IEC 60755) power, including systems with variable frequency drives.

Compare up to three products side by side:

RCMS460-D
Ground fault monitor for up to 12 grounded AC/DC systems
The RCMS460-D monitors for ground fault leakage current in grounded and high-resistance grounded single- and three-phase systems. The unit can switch between two different modes of operation: Type A (AC and pulsed DC signals) and Type B (AC, pulsed DC, and pure DC). Up to 12 different channels may be monitored simultaneously by one unit and one external BENDER current transformer for each sub-system. The RCMS460-D has large response value ranges (10mA...10A for Type B, 6mA...20A for Type A).

The RCMS460-D includes a digital LCD display with harmonics analysis and data logging, one common alarm relay, and the ability to connect the system via a FTC protocol converter to a network for monitoring on a computer.

  Also required: Current transformer: W0...W5 (AC only) or WAB (AC and/or DC)
  Use our CT Selector to find the correct and optimal CT for your system.

RCMS460-L
Ground fault monitor for up to 12 additional grounded AC/DC systems
The RCMS460-L monitors for ground fault leakage current in grounded and high-resistance grounded single- and three-phase systems. The unit can switch between two different modes of operation: Type A (AC and pulsed DC signals) and Type B (AC, pulsed DC, and pure DC). Up to 12 different channels may be monitored simultaneously by one unit and one external BENDER current transformer for each sub-system. The RCMS460-D has large response value ranges (10mA...10A for Type B, 6mA...20A for Type A).

The RCMS460-L includes a seven-segment display and one common alarm relay.

  Also required: Current transformer: W0...W5 (AC only) or WAB (AC and/or DC)
  Use our CT Selector to find the correct and optimal CT for your system.

RCMS490-D
Ground fault monitor for up to 12 grounded AC/DC systems
The RCMS490-D monitors for ground fault leakage current in grounded and high-resistance grounded single- and three-phase systems. The unit can switch between two different modes of operation: Type A (AC and pulsed DC signals) and Type B (AC, pulsed DC, and pure DC). Up to 12 different channels may be monitored simultaneously by one unit and one external BENDER current transformer for each sub-system. The RCMS460-D has large response value ranges (10mA...10A for Type B, 6mA...20A for Type A).

The RCMS490-D includes a digital LCD display with harmonics analysis and data logging, seperate alarm relays for each channel, and the ability to connect the system via a FTC protocol converter to a network for monitoring on a computer.

  Also required: Current transformer: W0...W5 (AC only) or WAB (AC and/or DC)
