The railway channel signal surge protector is mainly suitable for the surge protection of the railway low-voltage AC circuit, which is a composite SPD. The SPD module is equipped with a safety disengagement device and a failure indication window. When the internal protection element deteriorates, the tripping device operates to safely disengage the failure device from the system, and the corresponding module indication window displays red (fault).

Damage caused by electrical overvoltage, induced overvoltage, etc. The product is suitable for the signal line protection of railway signal machines, track circuits and other system equipment. It is plugged into the WAGO terminal block. It is equipped with a status display window and an identification pin for preventing wrong insertion. The pin can realize the separate test of lightning protection components. The parallel type is equipped with over-current and thermal tripping devices, which can realize hot swapping. A remote signaling contact for deterioration alarm can be added upon request from the customer.

The surge protection is set independently, and it can also be used as a lightning protection distribution cabinet. Each surge protector can protect a pair of signal transmission lines. Product features: 1. Large flow capacity; 2. Status display window, identification pin for preventing wrong insertion; 3. Various rated voltage options; 4. Stable performance, safe and reliable.
