+ SPD+POP+MCB / POP+MCB
Surge arrester for transient and power-frequency surges
- Comprehensive protection against transient and power frequency overvoltage (SPD+POP)
- Fulfils the requirements of EN 50550 "Power frequency overvoltage protective device"
- Prewired complete unit, individual devices do not have to be additionally wired
- Easy installation and retrofitting thanks to low space requirements
- High reliability due to "Thermo Dynamic Control" monitoring system integrated in the SPD
- Application-optimised discharge capacity of 5 kA (In) / 15 kA (Imax) (8/20 µs) per pole
- Energy coordination with other arresters of the Red/Line series
- Operating state / fault indication by green / red indicator flag in the inspection window of the SPD

Details
Electrical installations are increasingly damaged by overvoltage. This damage is not only caused by transient overvoltages, but also by power frequency overvoltages which result from e.g. instable systems or breakage of the neutral conductor.
The compact SPD+POP 2/4 255 C.. surge protective devices combine conventional surge protection (SPD) with power frequency overvoltage protection (POP) in an easy-to-install complete device.
The type 2 arresters ensure protection against transient overvoltages caused by e.g. inductive coupling resulting from a lightning strike or switching operations. The devices fully comply with the requirements of national and international product standards and feature a dual Thermo Dynamic Control monitoring device which ensures maximum reliability.
The POP 2/4 255 C.. surge protective devices can be used in installations which are already protected against transient overvoltage by other measures and comply with the European EN 50550 product standard for "Power frequency overvoltage protective devices".
If power frequency overvoltages occur, the connected miniature circuit breaker (MCB) disconnects the arresters, putting them into a safe state. When the miniature circuit breaker is reconnected, the system is checked for surges. If the system is still unstable and unbalanced surges are present, the miniature circuit breaker trips again.
Various types are available for different tripping currents of the miniature circuit breaker. This ensures that the surge protective device is is suitable for the parameters of the electrical installation.
Despite of the manifold functions, the devices take up little space: Four to seven modules are required for protecting an electrical installation. Therefore, the devices are can be easily retrofitted into existing electrical installations.
