Import Ex-Calibur Telephone Surge Protector - 3 Line — Buy in wholesale FOB from Supplier in India

The Ex-calibur Telephone Surge Protector - 3 Line is a line-level surge protection device designed to safeguard analog telephone lines from voltage transients caused by lightning or grid switching. It supports three simultaneous telephone lines, each with integrated gas discharge tube and transient voltage suppression circuitry, rated for 600V maximum continuous operating voltage and 10kA surge current capacity per line. The unit is housed in a compact metal enclosure with IP20 ingress protection and includes three LED indicators showing active status, surge protection status, and fault conditions.

This device uses standard RJ11 interfaces compatible with most analog telephony equipment and is built to meet IEC 61643-21 for low-voltage surge protection devices. The internal components are rated for industrial temperature ranges from -20°C to 60°C and are conformal-coated for humidity resistance. Typical industry applications include PBX systems, fax machines, modems, and alarm line interfaces. The protector does not include data line filtering or Ethernet protection; it is designed solely for voice-grade telephone lines.

Buyers commonly use this unit in corporate offices, call centers, and remote telecom nodes in regions with unstable power grids. The product is shipped in bulk packs of 10 or 25 units, each in anti-static polyethylene with foam inserts. Installation requires no tools and connects inline between the wall jack and the telephone device. Trade terms are typically FOB Bangalore, with lead times of 7 to 14 days after order confirmation. Buyers should confirm compatibility with their existing telephone system voltage standards before ordering.
