• It is applied to low-voltage ac distribution system, which is
connected in parallel between ac power supply and system equipment
to protect the damage caused by surge pulse and instantaneous
overvoltage caused by external (lightning strike, electromagnetic
radiation interference, etc.) or internal (system closing effect,
induction and start and stop of capacitive load, etc.).
• Protection against transient overvoltage for 230/400 V~ power
networks (50/60 Hz).
IP20 AC Surge Protection Device Advantage:
• Din rail type installation.
• Simple installation, easy maintenance.
• Function of overheating protection.
• Failure indicator window.
• Short action response time.
IP20 AC Surge Protection Device Installation:
• Before installation, it should be check whether the surge
protector is intact. If it is damaged or the display window is red,
it cannot be used; if the window is green, it is normal.
• Installation and maintenance shall be carried out by
professionals, and the installation shall be in a place out of
direct contact with human hands.
• Wiring according to the mark of surge protector according to the
wiring diagram.
IP20 AC Surge Protection Device Maintenance:
• After the failure of operation, automatic detachment is realized
through the thermal detachment mechanism protection system and
power supply line inside the module, and the display window becomes
"red". When the indicator window is "red", the surge protector
should be replaced immediately.
• Check the display window of the power module surge protector
after a thunderstorm.
