KUBE Clean Power

16 Amp/250VAC power line filter and surge arrestor KUBE TR 166

KUBE TR 166 is a highly effective filter against overvoltage and RF interference to protect computers or any other sensitive equipment from damage. It is intended for use in power strips (multiple socket outlets, Steckdosenleisten, multiprises) and is capable to carry the full current of 16 Amp without the need for an extra fuse.

The very compact dimensions allow mounting in power outlets and takes minimum space in power strips.

The KUBE TR 166 filter features a unique thermal cutoff mechanism to prevent a hazardous condition (fire) that may arise in certain situations. More than that, the KUBE TR 166 remains operational under such conditions and prevents data loss in computers and other consequences.

Optionally, two neon lamps may be connected (AMP 2.8 mm connectors):

red indicates that the surge arrester has been disconnected after overload (whereas the output voltage remains available)
green indicates that mains voltage is available.
