SINGLE PHASE LOW/HIGH CURRENT GUARD

SINGLE PHASE LOW/HIGH CURRENT GUARD

Product catalog summary
Overview: The document describes the KCC102E, a Single Phase Low/High Current Guard designed for monitoring single-phase generators or motors. It features a definite time trip delay and optional slave DIN96 indicator unit with full load current marking.
Key Features:
  • Two individually settable low/high current relays.
  • Fast analogue output (<50ms) for the F-version.
  • Compatible with 1A or 5A current transformers.
  • True RMS measurement for precision protection (1.0%).
  • Short circuit detection in less than 50ms.
Operation: R1 energizes when current is below the low trip level, and R2 trips when the high trip level is exceeded. R3 is an additional status relay that activates if either R1 or R2 is active, useful for local indication or alarm systems.
Specifications:
  • Auxiliary Voltage: 100-120, 200-240, 380-415, or 440-460VAC, 40-70Hz; Optional: 24, 48, or 110VDC.
  • Current Input: 1 or 5A C.T.
  • Contact Rating: AC: 100VA - 250V/2A max; DC: 50W - 100V/1A max.
  • Adjustments: High/Low level: 0-150% of FSD; Trip delay: 0-30 seconds; Hysteresis: 2-50%.
  • Analogue Output: Up to 20mA, max 500R; Up to 10V, min 100kohm.
  • Temperature Range: -20 to +70ºC.
  • Weight: 0.6kgs.
  • Front Protection: IP21.
Compliance: The unit complies with IEC60092-504 and relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533, meeting the requirements of major Classification Societies.
Additional Information: The document includes a diagram illustrating the relay operation and connections, highlighting the optional earth connection and analogue output.

True RMS measurement not affected by heavily distorted waveforms provides highest up precision (1.0%) protection. Less than 50mS short circuit detection. R1 energises when current is below trip level one (LOW) and R2 trips when trip level two (HIGH) is exceeded. R3 is an extra status relay that energises if either alarm relay 1 or 2 is active and can be used for local indication, PMS input, alarm system input etc. Fast response mAoutput signal proportional to a range (KCC102F). User settable trip levels and delays. Colour of LEDs indicates alarm status. LEDs flash during count-down. The unit meets IEC60092-504 and the relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with the requirements of the major Classification Societies.
