The ABB Furse ESP 415 M2 is a combined type one, two and three surge arrester housed in steel, used in demanding applications such as airports, hospitals, large businesses or residential premises such as high rise buildings. Suitable for installation at zone LPZ 0 for flashover protection through to boundary LPZ 3 where surge currents are more limited by shared interfaces, protecting valuable equipment like computers or machinery. Typically installed at distribution board location, protecting the circuit from transients or combating over-voltage in electrical switching applications.
A three-phase protector in compliance with IEC 61643-11, with low let-through voltage between all sets of conductors (phase to neutral, phase to earth and neutral to earth). Full mode protection handles partial lightning currents while electronic equipment operates uninterrupted as surges are diverted away to earth.
ESP 415M2 has multiple thermal disconnect technology that allows removal from defective supplies without detriment. An active voltage-free contact warns of phase loss from blown fuses, power down, faulty wiring, earthing issues, or unbalanced conditions. Warnings of status can be linked to a building management system, alarm or light.
At the front of the unit, lights indicate the status of each phase and neutral. Green indicates normal functioning; red denotes attention or replacement. A remote indicator option is available here.
