CNC 3P DC SPD 1500V Surge Protection Devices YCS8

General:

YCS8 series is applicable to photovoltaic power generation system. When surge
overvoltage occurs in the system due to lightning stroke or other reasons, the
protector immediately conducts in nanosecond time to introduce the surge
overvoltage to the earth, thus protecting the electrical equipment on the grid.

Features: 

T2/T1 + T2 surge protection provides two types of protection: voltage protection level Up < 1.5kV and Class I (10/350 µS waveform) and Class II (8/20 µS waveform).

T2/T1+T2 surge protection has two types of protection, which can can meet Class I
(10/350 μS waveform) and Class II (8/20 μS waveform) SPD test, and voltage
protection level Up ≤ 1.5kV;

Modular, large-capacity SPD, maximum discharge current Imax=40kA;
Pluggable module;

Fast

Based on zinc oxide technology, it has no power frequency aftercurrent and fast
response speed, up to 25ns;

Indicator

The green window indicates normal, and the red indicates a defect, and the
module needs to be replaced;
Dual thermal disconnection device provides more reliable protection;
Remote signal contacts are optional;

Its surge protection range can be from power system to terminal equipment;
It is applicable to direct lightning protection and surge protection of DC systems
such as PV combiner box and PV distribution cabinet.

Release Device for Failure, Release Device for Alarm

Failure Protection Feature:
In addition to surge protection, this device is equipped with failure protection. If the protector overheats and fails, the built-in protection mechanism will disconnect it from the power grid and send a warning alert to notify you.

• Green indicator when the protector is functioning properly.
• Red indicator when the protector fails to work correctly.

Alarm Signal Functionality:
The device can be configured to provide various types of remote signaling contacts. It includes normally open and normally closed contacts for remote signaling.

• Normally closed contacts are linked when the protector is functioning correctly.
• If one or more modules of the protector fail, the contact will shift from normally open to normally closed, triggering an alert. The normally open contact will continue to function and send a fault message.
