LPS® PM40 Series
They protect Distribution Boards (DB) receiving energy from Sub-Switchboards Boards (SSB) located in the same buildings
Following extensive R&D, these devices have been created to deploy state-of-the-art engineering technology to protect your equipment effectively even in the most lightning prone regions in the world. The LPS® PM40 Series devices are reliable surge protectors designed to protect electronic and electrical equipment. They are ideal for sub-switchboards and distribution boards of commercial and industrial buildings, as well as main switchboards for homes and office units.
LPS® PM40 Series devices provide 40,000 amps per phase of surge protection in common and differential modes with instantaneous response. Thus your equipment is protected from lightning surges caused by direct lightning strikes, electro-magnetic couplings, the switch of power networks as well as from inductive loads.
Metal Oxide Varistors (MOVs) are used to maximise performance and reliability. LPS® PM40 Series devices are specially designed with built-in thermal cut-out fuse that assist in avoiding fire hazards when dangerous thermal run-away occurs.
Each device is equipped with a LED indicator. LPS® PM40-220 and PM40-480 have additional audible alarm which provides users with audio monitoring on protection status. Furthermore, they are also armed with a NO/NC dry contact for remote monitoring on protection and power supply status with user-friendly RJ II connector.
How they works
LPS® PM40 Series devices provide unsurpassed performances in lightning surge protection. When a transient surge occurs, the surge protective devices will switch to a fully conductive state to divert high current. They will then reset automatically to a non-conducting state when the current falls below the varistor voltage.
