Explosion-proof SPD EX-L 〔〕 type

拡大

 

This product is an explosion-proof SPD that is used to protect equipment from irregular voltage induced into power cables and communication and signal cables, etc., in explosion-proof areas such as petrochemical plants, heavy chemical plants, etc., and is a IEC 61643-21compliant SPD (surge protective device).

 

Category C2, D1 compliant
Certification of Explosion-proof is only applied in Japan.  
In other countries case, please consult to us. 

 
 
 
     
 
●IEC 61643-21 Category C2, D1 compliant CLP- 〔〕 type communication and signal SPD mounted
