Product Picture

rep-bc25t1t2-320-4s-02

(BC25T1+T2-320-4S)144mm

 

Features

Combination T1+T2 SPD surge protector;

ClassI+II/B+C surge protector in accordance with IEC61643 and UL1449-4th;

It can fulfill two classes protection in the same place with minimum installation work and space-saving design;

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 signaling contact optional and failure indicator.
