Indirect lightning solutions and LITOL lightning arresters for electrical panels (LTP series)

Instantly Responds to lightning-induced electrical surges to protect all types of equipment.

The LITOL (LTP) line surge protector has been developed by Mitsubishi Materials to protect all types of equipment from lighting-induced electrical surges (lightning damage). It achieves superior responsivity and a maximum discharge current of 20 kA. It can also be installed easily on the DIN rails of control boards and distribution boards.

Features

  • The equipment between lines and between a line and earth can be protected using a single unit.
  • Resistant to repeated electrical surges and has a long usage life.
  • It is very easy to handle and install (DIN rails are supported)
  • Rated voltages AC 125 V, AC 250 V, and AC 400 V are supported
  • Max. discharge current: 20 kA
  • Also protects against switching surges and back-flow lightning surges

Applications

  • Distribution boards in plants
  • Panel boards
  • Distribution boards for large-scale buildings (hospitals, schools, and collective housing)
  • Gas stations
  • Industrial refrigerators
