Durable Type 1 Surge Protection Device Uc 385v 50ka Built - In Temperature

Product Specification

Type 1 surge protective device is characterized by a 10/350 µs current wave

Brief introduction

   The surge protector is the lightning protection measure adopted by Zhejiang toer Electric Co., Ltd. for the electrical system. It is designed and manufactured according to IEC and GB standards. At the same time, it meets the requirements of IEEE802.3AT. We use the brand components to make use of advanced production technology, with large flow capacity and residual pressure level. Low, sensitive, stable performance, reliable work and so on, let you no matter what weather can be safe to use, rest assured use, no longer worry about the rain weather what harm!

Product features

  1. built-in overheating and temperature control circuit breaker

  2. self protection voltage is more than self protection, automatic disconnection and recovery.

  3. Easy to install with  small sizes

Working principle of product

   During the operation of the equipment, the lightning arrester will play a protective role once the abnormal voltage occurs. When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally. The main function of the arrester is to reduce the voltage value of the protected equipment by the action of parallel discharge gap or nonlinear resistance, so as to protect the power equipment.

Product Installation

   With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35mm²

At front of spd each pole must be setted protection---used fuse or miniature circuit breaker lightning current SPD protection,after SPD breakdown to short circuit protection.

   SPD install on protected line(equipment) to the front and connected to the supply line. A class products install in the building home-entry line hold larger surge current total distribution box. B, C class products most install on the floor distribution box, D class products close to the front-end equipment that smaller surge current, smaller residual voltage place.

Use of attention

  1.The PE line of the  lightning arrester must be reliably connected with the ground wire of the lightning protection system, and the connection line is short, thick and straight.

  2. lightning protector's input port (IN) is connected to the signal channel, and the output terminal (OUT) is connected with the input end of the protected device, so it can't connect with the signal.

  3. this product needs no special maintenance. The lightning arrester should be checked regularly, especially in the thunderstorm season and the whole thunderstorm period. When the system fails to suspect the lightning arrester, the lightning arrester can be dismantled and rechecked. If the system is restored to normal after the restoration to the state before use, the lightning arrester has been damaged and must be replaced immediately.
