The ABB Furse ESP 415 M1R features a remote display, allowing the protector to be mounted close to the incoming feed, first way on the distribution board, in hard to access areas or inside enclosures with the indicator visible elsewhere or on the outside of a cabinet.
A combined type one, two and three surge arrester housed in steel. The compact size enables installation on distribution boards, protecting the circuit after that from transients and lightning currents. Also suitable for protection during electrical switching applications. Electronic equipment will continue to operate without interruption.
A three-phase protector conforming to IEC 61643-11. Suitable for installation in zone LPZ 0, where higher surge currents prevail, providing flash over protection. Also can be used at LPZ 3 boundary, where surge current is more limited, safeguarding equipment such as computers and machinery from overvoltage damage, by diverting surges harmlessly to earth.
The ESP 415M1R can be removed from faulty supplies without affecting performance. An active voltage free contact provides warnings of phase loss, blown fuses, power out, incorrect wiring, earthing or unbalanced conditions. Status can be sent to a building management system, alarm or light.
The remote indicator lights show the status of each phase and neutral. Green indicates regular operation; red signifies maintenance or replacement. Standard unit with integrated indicator here.
