Features of THOR Surge Protective Device
The Type 2 SPD is the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of overvoltages in the electrical installations and protects the loads.
Type 2 surge protective devices (SPDs) are designed to protect electric installations and sensitive equipment against indirect surges and ensuring a low protection level (Up).
Type 2 surge protective devices provide effective protection against these dynamic disturbance variables. Whether in an industrial environment or in a residential building, type 2 protection ensures basic protection for your installations and devices.
The TRS4 series type 2 SPDs are available have a discharge capacity of 10kA, 20KA, 40KA, 60KA in single-phase or 3-phase configuration and with various voltages in order to protect any type of power supply system.
THOR Type 2 DIN-rail SPD features are offering quick thermal response and perfect cut-off function and providing fast and reliable protection for various power supply systems.And its capacity to safely discharge current with 8/20 μs waveform.
Built with window fault indication and optional remote alarm contact, it can monitor the operating status of the SPD itself.
