Details：
For customers who demand a protector rated for a maximum surge current greatly in excess of the probable worst case (BS 6651, IEEE C62.41). Suitable for three phase (346-484V) supplies, whatever their supply current. For a maximum surge current rating of 60kA (unit total 240kA) use ESP 415 M2. For a maximum surge current rating of 120kA (unit total 480kA) use ESP 415 M4.
Application
Use these units at the main low voltage distribution board for extra high surge current protection. Typical uses include the protection of:
computer equipment transmitter/receiver systems uninterruptible power supplies (UPS) drives and inverters programmable logic controllers (PLC) medical equipment
Features and benefits
Designed to protect and survive in lightning intense environments.
Very low let-through voltage restricts dangerous transient overvoltages to below the damage levels of equipment circuitry.
Protection between all sets of conductors (phase to neutral, phase to earth and neutral to earth) ensures total protection, closing all transient paths to equipment.
Extra high maximum surge current of 60kA (240kA unit total ) for ESP 415 M2 and 120kA (480kA unit total) for ESP 415 M4.
Repeated protection in lightning intense environments with 20 years predicted lifetime.
Innovative new Sovtrip™ multiple thermal disconnect technology, anticipates standards authorities future demands, 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 (ie 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.
Simple parallel connection.
Protector base provides ultra low inductance earth bond to metal panels.
Convenient holes for flat mounting.
Compact size for installation in the power distribution board.
Straightforward, comprehensive installation instructions with every unit.
Maintenance free.
5 year warranty.
Installation
Install in parallel, within the power distribution board, either on the load side of the incoming isolator, or on the closest outgoing way to the incoming supply. Connect with very short connecting leads, to phase(s), neutral and earth.
On supplies over 100 amps, phase/live connecting leads should be fused with a either a 63 or 100 amp high rupture capacity (HRC) fuses, a switchfuse, MCCB or type C MCB.
Parallel connection to three phase star (4 wire and earth) supplies.
Parallel connection of ESP 415 M1 or ESP 208 M1 to three phase star (4 wire and earth) supplies.
Suitable accessories
Where the protector can not be incorporated within the panel use the wbx m2 enclosure for the ESP 415 M2 or the wbx m4 for the ESP 415 M4.
