T1 SPD can be used as replacements for what were known as secondary surge arresters for lightning arrestors

Product description

Surge protector is a lightning protection measure adopted by Zhejiang tohr Electric Co., Ltd., which is independently developed and manufactured for electrical system. The shell is installed on the 35mm electric rail. The product has built-in failure detaching device. When the surge protector overheat and breakdown, the failure exfoliation device can automatically remove it from the power grid, and the alarm indicator module is turned from white (normal) to red (fault).

Product features

1. Safety insulation of fire retardant and high flame retardant material

2. leakage current is small, the response time is fast, and the residual pressure is low

3. detachable assembly and pluggable convenience

Product specification

Working principle of product

Under normal working condition, the lightning protection module is in a high resistance state. When the power supply line has lightning invasion or operation transient overvoltage, the lightning protection module will immediately pass through the response speed of nanosecond level, and limit the lightning overvoltage or transient overvoltage to the voltage range allowed by the electrical equipment, thus protecting the normal operation of the electronic equipment. After that, the lightning protection module quickly returns to the high impedance state without affecting the normal power supply of the grid.

Use of attention

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

2. the relative humidity of the installation site is not more than 50% when the relative humidity of the air is 40.

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.

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.
