T1+T2 Surge Protector for Wind Turbine

Combination T1+T2 SPD for power supply system of wind turbine with spark gap+Mov technology

PRODUCTS DETAIL

Product Picture

(MS25T1+T2-760-5S)108mm

Features

The combination type I +type II surge protector can be installed at zero distance from the subsequent II surge protector without decoupling inductance;

Non exhausting encapsulated spark gap technology;

The smallest size in the industry, Iimp=25kA, Uc=760Vac, saving half of the space;

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.
