Self-Regulating Heater Cable, Sold by the metre, up to 20 m

Self-Regulating Heater Cable

• Prevents the water pipes from freezing in frosty conditions
• Heat output 15 W per metre at 0 °C (9 W per metre at 10 °C )
• The heat output is automatically and continuously adjusted in relation to the pipe temperature
• The cable can be shortened or lengthened
• Multiple divisions are possible
• Maximum section length 100 m
• Damages can be repaired
• The heat output is automatically adjusted to cope with different temperatures in different parts of the system
• Maximum length 150 m with 16 A fuse
• Note: to regulate the max. water temperature, the contact thermostat (ref. 381520) must be installed

Mode of operation:

The two electrical conductors are set in an insulating polymer that contains graphite particles.

1. When it is cold: the polymer contracts, the graphite particles come into contact with each other, the cable becomes warm
2. When it is warm: the polymer expands. There is no contact between the graphite particles, the cable does not heat

• 230 V connection
• Max. 12 W / m (at 0° C)
• RCD 30 mA required on site
• Protection grade IP 54 (splash-proof)
