SHORT-CIRCUIT INDICATOR TYPE K/KM/KH

Product catalog summary

General Description: The document describes a short-circuit indicator used in radial and open-ring networks. It is a single unit mounted on each conductor, with a flag indicator for short-circuit detection. The device does not require a power supply for operation and is available in three types: K, KH, and KM, each with different reset mechanisms.

Specifications:

Short-circuit current range: 150 to 1500 A, with optional four trip currents.
Display unit dimensions: 40mm x 50mm x 38mm, protection class IP67.
Reset options: Manual (Types KM and KH) or automatic (Types K and KM) after voltage recovery.
Operating temperature: -40°C to +80°C, with 100% maximum humidity.
Compliance with IEC 61243-5:1997 and IEEE 495-2007 standards.

Installation and Compatibility:

Suitable for surface installation with standard steel frames.
Compatible with round conductors (15-65 mm) and flat conductors (up to 60x15 mm).

Testing and Standards: The device has undergone impact, salt fog, and impulse voltage tests as per IEC standards, and EMI tests according to IEC 1000-4-2 and IEC 1000-4-3.

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
