Self-Regulating Heating Cable KSX

Application

High performance KSX self-regulating heating cables are designed specifically for high heat loss freeze protection applications or process temperature maintenance where steam cleaning is not required.

The heat output of KSX cable varies in response to the surrounding temperature by reducing its thermal output with increasing temperature.

KSX cables are certified for use in ordinary (nonclassified) areas and in potentially explosive atmospheres in accordance with the ATEX Directive and the IEC Ex Scheme.

Features Cable KSX

Freeze protection.
Low process temperature maintenance.
Withstands continuous flammability testing according to IEC 60332-1: 1993.
Can be installed at temperatutes to - 60 ^oC.

Construction Thermon KSX

Конструкция Thermon KSX 1. Nickel-plated copper bus wires (1.3 mm²)

2. Semiconductive heating matrix and fluoropolymer dielectric insulation.

3. Tinned copper braid.

4. Fluoropolymer overjacket provides additional protection to cable and braid where exposure to chemicals or corrosives is expected.

Circuit breaker sizing and type

Maximum circuit lengths for various circuit breaker amperages are shown below. Circuit breaker sizing and earth-fault protection should be based on applicable local codes. For information on design and performance on other voltages, contact Thermon. Earth-fault protection of equipment should be provided for each branch circuit supplying electric heating equipment.
