KEC103x - SINGLE PHASE UNDERCURRENT GUARD
- Single Phase Undercurrent Protection with Definite Time Trip Delay
- Two individually settable undercurrent relays
- For use with 1A or 5A current transformers
- Very fast analogue output (<50mS), (F-version)
- Independent ammeter with full current scale
KEC103x series provides current underload protection of single phase generators or motors.
True RMS measurement not affected by heavily distorted waveforms provides highest up precision (1.0%) protection. Less than 50mS undercurrent detection.
The independent class 1,5 moving iron ammeter input (term. 26 & 27) MUST be externally connected to read phase current.
R1 energises when trip level one (Undercurrent 1) is exceeded and R2 trips when trip level two (Undercurrent 2) 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 analogue output signal proportional to a range (KEC103F & KEC103GF).
User settable trip levels and delays. Colour of LEDs indicates alarm status. LEDs flash during count-down.
The unit meets EN 61010-1 Cat. III, Pollution degree 2 and the relevant environmental and EMC tests specified in EN 61326-2-4 to comply with the requirements of the major Classification Societies.
