Product Description
Summary:
For installation at LPZ 0B-1 or higher, mainly used in the main distribution system to protect the connected electronic devices from the transient over voltage on the power supply system. For example, computer, communication, or control equipment. Designed according to IEC 61643-11 / EN61643-11 / GB 18802.1.
Main Character:
• Surge arresters for class I+II+III single-phase TT/TN system
• All wires (phase line to neutral line, phase line to ground, neutral line to ground full protection model), Voltage protection level is very low
• Full protection design, able handle part of lightning current, protection equipment can continue normal operation
• Visual protection status indication, with pre-failure indication and failure indication function
• Solid housing, base can be used as ultra-low inductance grounding metal panel
• External wiring terminal and remote alarm terminal, easy for connection, suitable for indoor application
