LPS® PM120 Series
They protect main switchboards and sub-switchboards of commercial, residential and industrial buildings
The LPS® PM120-220 and PM120-480 devices are reliable surge protectors designed to protect electronic and electrical equipment. They are ideal for main switchboards and sub-switchboards of commercial, residential and industrial 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.
LPS® PM120-220 and PM120-480 devices provide 120,000 amps per phase of surge protection 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® PM120-220 and PM120-480 devices are specially designed with built-in thermal cut-out fuse that assist in avoiding fire hazards when dangerous thermal run-away occurs.
These devices are equipped with a LED indicator as well as an audible alarm which provides users with visual and 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 work
LPS® PM120-220 and PM120-480 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 voltage falls to normal operational value.
- They protect main switchboards and sub-switchboards of commercial, residential and industrial buildings
- They are designed with thermal cut-out fuse that assist in avoiding fire hazards when dangerous thermal run-away occurs
- They are housed in a fail-safe IP 20 metal enclosures for maximum safety
