220v appliance surge protector Low-voltage power system lightning protector

Brief introduction

The product is a surge protector for the plug type low-voltage distribution system, including the replaceable element, and the voltage limiting element is made up of a metal oxide varistor in parallel. Each varistor requires an independent disconnector. The principle of the disconnector is a heat release. The function is disconnected through the low temperature welding point and is separated from the metal rod by its own elastic action. After disengagement, the red indication will appear in the transparent window on the front side of the surge protector.

Use of attention

1. device is a series connection mode.

2. it should match the working voltage of the protected equipment. Please install according to the installation sketch.

3. lightning protection device IN as input and OUT as output, the input end is connected with the outside, and the output end of the input end of the connecting device is protected.

Product features

1. able chips can react quickly when problems appear.

2. Easy to install in small size

3. cut off the line when undervoltage occurs, and reset automatically after restoration.

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.

Product specification

Working principle of product

When the surge protector has no voltage, the impedance is very high, which means that the circuit breaker is open. When the voltage occurs, the impedance drops to a few Europe, and the surge current will flow through the surge protector and will not enter the device. At the same time, because the surge protector has a small impedance at this time, the voltage on both sides of the surge is relatively small, and because he is in parallel with the protected equipment, it prevents the equipment from suffering from large surge power. Pressure, so as to play the effect of discharge and pressure limiting.
