High Surge Current Signal Line Protectors

SLD Signal Line Protectors are designed to protect the most sensitive electronic

equipment in lightning intense environments. So they are ideal for the protection

of PLC’s, fire and security systems, railway signalling and SCADA equipment.

Multistage Transient Protection

Models featuring multistage transient protection deliver greater levels of

protection through a staged approach. The primary stage absorbs the majority of

the surge energy. The remaining stages provide accurate clamping and a degree

of redundancy.

Surge Current Fusing

Surge current fuses allow components to absorb maximum energy but in

the event of a component failure the fuse will open to isolate the damaged

component.

Safe Metal Enclosure

Novaris surge protection products are housed in safe, all metal enclosures. In

the event of a prolonged overvoltage they will not catch fire or explode.
