Type 2 AC surge protector
EN 61643-11/IEC 61643-11 compliant
In the presence of an overvoltage, this impedance falls to very low values, closing the circuit to earth/ground.
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 TRS7 series type 2 SPDs are available have a discharge capacity of 80kA, 100KA, 120KA, 150KA 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.
