SHORT-CIRCUIT INDICATOR TYPE K/KM/KH single conductor mounted

Product catalog summary

General Description
The short-circuit indicator is designed for use in radial networks with one input and open-ring networks. It is a single unit mounted on each conductor, featuring a sensor with integrated indication via a flag indicator. The device is divisible and can be retrofitted, requiring no power supply for operation.

Versions

Type K: Automatic reset by recovering operating voltage. Suitable for unscreened cables.
Type KH: Manual reset with a button. Can be mounted on both screened and unscreened cables.
Type KM: Offers both automatic reset by recovering operating voltage and manual reset. Suitable for unscreened cables.
