Surge Arresters – Type 3

SPS Protector
• 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

For protecting the power supply circuits of industrial electronics equipment (e.g.
programmable logic controls (PLCs)) against transients and high-frequency inter-
ference voltages. For installation in conformity with the lightning protection zone
concept at the boundaries from 1 – 2 and higher.

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

The SPS Protector combines surge protection and interference suppressor
filter in a compact device. This makes it ideal for protecting sensitive ter-
minal equipment of industrial automation systems (e.g. programmable
logic controls (PLCs)). The coordinated surge protection and filter func-
tions 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 en-
closure of the SPS Protector ensures that high-frequency interferences are
discharged without interfering with other devices in the immediate vicin-
ity. The compact design of the SPS Protector already houses the proven
disconnector. In case of overload, it disconnects the arrester without in-
terrupting the power supply circuit. Apart from the green indicator light,
SPS Protectors also feature a remote signalling contact.
