AC Ground Fault Monitor, Latching Output, Analog Output, (3 Individual Channel)
For grounded or non-grounded live networks in land, marine and sub-sea installations
3 Individual channels, True r.m.s. measurement
Non-resistive earth current offset function
Restricted or Unrestricted earth fault detection
Highest up meter reading, Pathfinder function identifies channel trip
Analogue output proportional to highest earth current level (F-version)
The three channel digitally controlled KPM363x monitors up to three earth current channels in a non-grounded (IT) or grounded TN network and its protective earth. Unit can be used for either Restricted or Unrestricted earth fault detection. There is individual relay for alarm or trip of load breaker.
The unit reads the level of earth leakage directly in mA. The standard range is 0-150mA. Larger scale values are available, typically 500mA, 1A, 2A, 5A and 10A. The 3-channel KCM363x automatically locks the meter to read the highest of the three channels.
An AC or DC auxiliary voltage is required for the unit. Start of monitoring function is inhibited when auxiliary power is switched on (default 2secs delay). In this way false tripping during power up.
The meter status LEDs give at a glance the clear safety message:
