DATA SHEET SHORT-CIRCUIT INDICATOR TYPE K/KM/KH single conductor mounted General description The short-circuit indicator can be used in radial networks with one input and open-ring networks. The short-circuit indicators are single units and mounted on each conductor. The short-circuit indicator type K / KM / KH consists of one sensor with integrated indication. The indication is done by a fl ag indicator. The indicator is divisible and can be retrofi tted. 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. Type KM: Automatic reset by recovering operating voltage and manual reset. The indicator must be installed on unscreened cables. ELEKTRO-MECHANIK EM GMBH Ringstr. 4 - D-42553 Velbert / Germany Tel: +49 2053 422890 - Fax: +49 2053 422899 www.emg-ger.com
