ESP M2/M4 Series
The ESP M2/M4 Series is a combined Type 1, 2 and 3 tested protector (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 all sets of conductors (phase to neutral, phase to earth, neutral to earth - Full Mode protection)
-
Full Mode design capable of handling high energy partial lightning currents as well as allowing continual operation of protected equipment
-
Innovative multiple thermal disconnect technology, for safe disconnection from faulty or abnormal supplies (without compromising protective performance)
-
Three way visual indication of protection status
-
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
-
Protector base provides ultra low inductance earth bond to metal panels
-
Convenient holes for flat mounting
