ESP MT1 Series

The ESP MT1 Series is a combined Type 1, 2 and 3 tested Surge Protective Device (SPD) (to BS EN 61643) for use on the main distribution board directly feeding electronic equipment such as computers, communication and control equipment, particularly where a structural Lightning Protection System (LPS) is employed.

For use at boundaries up to LPZ 0 to protect against flashover (typically the main distribution board location) through to LPZ 3 to protect sensitive electronic equipment.

Features & benefits

Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between phase and neutral conductors, where sensitive equipment is connected
All mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment
Repeated protection in lightning intense environments
Innovative multiple thermal disconnect technology for safe disconnection from faulty or abnormal supplies (without compromising protective performance)
Three way visual indication of protection status and advanced pre-failure warning so you need never be unprotected
Remote indication facility allows pre-failure warning to be linked to a building management system, buzzer or light
Changeover active volt-free contact enables the protector to be used to warn of phase loss (i.e. power failure, blown fuses, etc)
Unique flashing warning of potentially fatal neutral to earth supply faults (caused by incorrect earthing, wiring errors or unbalanced conditions)
Robust steel housing
SPD base provides ultra low inductance earth bond to metal panels
Convenient holes for flat mounting
