Analog switch surge manufacturers

Features:

◆ Zui large discharge current 20kA
◆ It can be plugged and unplugged at any time, and the module can be replaced at any time without affecting the normal signal transmission. ◆ Modular 35mm electrical rail installation. ◆ The base can be used as a terminal for signal wires.

Installation Precautions:
① The signal line surge protector should be connected to the signal port of the protected equipment. Surge protectors can be installed in cabinets or fixed on equipment racks or nearby supports.
② The ground end of the signal line surge protector should be connected to the equipotential connection network of the equipment room with a copper core wire with a cross-sectional area of not less than 1.5 mm2. The ground wire should be short and straight.
③ The ground wire and surge protector connecting wire should be more than 90 degrees when turning, and the bending radius should be more than 10 times the diameter of the wire.
④ The outdoor signal cables introduced into the indoor should be laid through steel pipes, and both ends of the steel pipes are grounded.
