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 customers乫choice, 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
