SPS Protector

Two-pole surge arrester with filter

For protecting the power supply circuits of industrial electronics equipment (e.g. programmable logic controls (PLCs)) against transients and high-frequency interference voltages. For installation in conformity with the lightning protection zone concept at the boundaries from 1 – 2 and higher.
  • Combination of surge protection and filter
  • Surge protection with monitoring device and disconnector
  • Interference suppressor filter for protecting sensitive industrial electronics equipment against balanced and unbalanced high-frequency interference
  • Integrated in a shielded enclosure
  • Visual operating state indication (green) and floating remote signalling contact (break contact) for fault indication

SPS Protector: Two-pole surge arrester with interference suppressor filter

Details

The SPS Protector combines surge protection and interference suppressor filter in a compact device. This makes it ideal for protecting sensitive terminal equipment of industrial automation systems (e.g. programmable logic controls (PLCs)). The coordinated surge protection and filter functions complement one another and prevent core saturation of the filter in the event of high-level transients. The separate input and output terminals provide optimal protection for the device to be protected. The metal enclosure of the SPS Protector ensures that high-frequency interferences are discharged without interfering with other devices in the immediate vicinity. The compact design of the SPS Protector already houses the proven disconnector. In case of overload, it disconnects the arrester without interrupting the power supply circuit. Apart from the green indicator light, SPS Protectors also feature a remote signalling contact.
