Product Description

Yellow 20ka 3 Phase Surge Suppressor , AC Surge Protector 385V For Machine Room 

surge protective device(SPD) is designed according to IEC61643 standard. It is accordance with the criterion of Low-voltage Surge Protective Devices-Part 1: Surge Protective Devices Performance Requirements and Test Method of Low-voltage Power Distribution System. With good sealing, it is designed as module and 35mm din-rail mounting. With working indication window, temperature control circuit breaker and built-in over-current protective circuit, this SPD can release automatically to avoid fire danger when it breaks down. With remote alarm connector, it is convenient for remote monitoring. The main module and the base are replaceable. The lightning protection modes is L-PE, N-PE (2P/4P) or L-N-PE (1+1P) / (3+1P).
Surge protection device(SPD) is an indispensable device for lightning protection of electronic equipment. It is used to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or A powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.
These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary. In addition, the QR code printed on the arrestor allows disary. In addition, the QR code printed on the arrestor allows direct access to the online installation instructions.

+ Connectable surge arrestor

+ High arresting capacity

+ Visual status display

+ Available with optional remote signalling

+ Vibration-proof

+ Simple standard hat rail mounting

+ Labelled connections

+ Voltage encoding

1.Do power off when connect surge protection device to system.
2.Ground wire should be as short, straight and thick as possible to reduce the influence of distributed inductance on lightning discharge.
3.No need special maintenance. When surge protector happens fault,equipment connected to remote signal will send alarm, then power off and change new surge protector module is fine.
