Thermarestor T1150 Neutral/Intake

Part Number : U0185142


Thermarestor T1150 offers a significant step forward in the protection of electrical distribution equipment. The faults that can occur within consumer units and distribution boards which lead to excessive heat and / or fire can be eliminated by the installation of Thermarestor System.

By responding to temperatures of 80ºC ± 5°C and before any signs of fire, the resulting activation of the safety devices within Thermarestor T1150 can be configured to operate a Residual Current Device (RCD) or signal other types of Thermarestor Approved Devices (TAD), fire alarm, security alarm and business maintenance systems.

The Thermarestor is simple to fit and can be subjected to all routine installation tests including insulation tests. T1150 is designed to allow single point detection within electrical distribution boards and to monitor electricity supplier equipment, for example, cut out fuse and meter tails.
