440V 80KA Type 2 Surge Protection Device Fire Retardant Stable Performance

Industrial lightning surge protector, surge arrester, 275V 385V 420V surge protector

Brief introduction

The power supply surge protector, also known as the power supply lightning protection device, is suitable for the AC 50/60HZ, the rated voltage 220V/380V power supply system, the indirect lightning and direct lightning impact or other instantaneous overvoltage surge protection, suitable for home housing, the third industry and industrial field surge protection requirements, with relative phase, relative. The relative middle line, the middle line to the ground and its combination protection mode.

Product features

1. core components are strictly screened, stable performance and reliable operation.

2. advanced production process and beautiful appearance

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

4. adopt the latest arc extinguishing technology to avoid fire.

Notice of product

1. when installing, pay attention to cables coming in and out of surge protective devices, so as to avoid the two coupling of surge.

2. the protected equipment must have good grounding, and the grounding impedance value is according to the relevant standard.

3. After correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.

Product specification

Structure and Principle

SPD is a port, shocking protection, indoor-mounted installation, voltage-limited.

SPD hold disconnector inside, when SPD breakdown failure by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is working properly, visible window display green, it display red when it breakdown and disconnect.

1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground protection module, apply to TN-S, TN-C-S and other power supply system.

Working principle of product

The lightning arrester can effectively protect the power equipment. Once the abnormal voltage appears, the lightning arrester will play a protective role. 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 lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect the power equipment.
