MYS5 Series

Detailed product information


MYS Type

MYS5 type over voltageprotector is mainly applied to the 3nd & 4th class protection between 380Vpower system wire and zero to ground. The product can be assembled freely atthe customerschoice, such as single module, 4 modules combination with one base and 220Vsingle phase power with both asymmetrical interference protection structures.

Features:

· Greatabsorbing capability(5kA~20kA), low clamping voltage

· Fastresponse

· Themodules can be replaced without switching the power off

· Available with double monitoringseparation device controlled by thermo fuse and current fuse

· Withremote monitoring alarm terminals

· Thered window shows failure
