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

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.
