Type K / KM / KH
The short-circuit indicators type K, KH and KM can be used in radial networks with one input and open-ring networks.
The short-circuit indicators are single units of one sensor with integrated indication. The indicators are mounted on each conductor. The indication is done by a flag indicator. The indicator is divisible and can be retrofitted.
For the operation of the display device no power supply is required.
The short-circuit indicator type K is available in three versions:
Type K: Automatic reset by recovering operating voltage. The indicator must be installed on unscreened cables.
Type KH: Manual reset with a button. The indicator can be mounted on screened and unscreened cables.
