Surge Protection
Surge protection refers to the protection of systems and electrical devices against excessively high voltage peaks caused by switching operations and lightning strikes. An effective lightning protection strategy combines internal and external lightning protection. Protect the power supplies, data, and signals in your system. Use the reliable surge protection solutions available in our various product ranges as part of your internal lightning protection strategy.

Isolating spark gap
Use our isolating spark gaps to protect your insulating flanges against damage caused by overvoltages. Avoid failures, downtimes, and even leaks on pipelines and protect sensitive insulating flanges against sparkover. The isolating spark gap ensures lightning protection equipotential bonding and safely discharges overvoltages. This in turn ensures smooth operation of the pipeline.
String combiner boxes for photovoltaic systems
It is necessary to use string combiner boxes to provide ideal protection for PV systems against lightning strikes and overvoltages. Our turnkey string combiner boxes, which can be connected immediately, are reliable system solutions that protect the inverter directly from DC and AC voltage inputs. Overvoltage couplings are diverted directly to the ground potential.
Surge protection for information technology and telecommunications
IT interfaces are particularly sensitive to overvoltages. Ideally, high transmission rates should not be impaired by the protective circuit. Powerful and fast-acting components provide a good level of protection with minimal attenuation. Overvoltages are safely limited. The bandwidth remains virtually unaffected.
Surge protection for MCR technology
In measurement and control technology (MCR technology), surge protection ensures interference-free signal transmission. The high quality and availability of the transmitted signals is essential for smooth operation. Our surge protective devices offer an ideal solution for all applications in MCR technology. System failures can thus be avoided.
Type 1, type 2 and type 3 surge protection for power supplies
Type 1, 2, and 3 surge protection protects against malfunctions and defects caused by overvoltages. In the absence of effective protection, high costs are likely due to system failures. In the worst-case scenario, the affected equipment will need to be repaired or replaced. The multi-stage concept from Phoenix Contact provides effective protection for systems and devices.
Surge protection for transmitter and receiver systems
Antennas are real lightning conductors. Use powerful surge protection with low attenuation. Play it safe with our powerful COAXTRAB coaxial protective devices. Select the right low-capacity protective circuits to achieve low attenuation and high bandwidth. Thanks to excellent impedance matching, surge protection does not distort the useful signal.
Test and monitoring devices
Whether cloud-based in real time or manually, our test and monitoring devices are a convincing way to increase system availability. Overvoltages can overload electrical installations and the protective devices intended to protect them. Determine the state of your system and your surge protection at an early stage, before failures occur.
