Small SPD(MS25-320-4S)

 SPD(MS25) with  minimum dimension for three phase with Spark gap+Mov technology

PRODUCTS DETAIL

Product Picture

--_1

(MS25-4S)72mm

 
 

 

Features

Combination T1+T2 SPD surge protector with minimum dimension only 72mm for three phase; 
Non exhausting encapsulated spark gap technology with extremely high surge capacity;
High follow current extinction and limitation due to no follow current;
Reliable supervision due to new LTR energy control technology;
With remote signal contact optional and mechanical failure indicator.
