The TC-440/80 is a high energy multi stage three phase primary clamp providing precision clamp protection for electrical/electronic equipment connected to three phase distribution systems.
The TC-440/80 is a primary high energy shunt device with a transient fault rating of 80kA per phase and an additional unique Neutral/Earth protection that is fully monitored.
The TC-440/80 is used on mains distribution systems to protect connected electrical/electronic equipment from transient over voltages on the three phase mains supply.
