FAQs
What does 'TN-C' mains form mean?
TN-C stands for 'Terra-Neutral-Combined', meaning the neutral and protective earth conductors are combined into a single conductor throughout the system.
What is the IP20 rating?
IP20 means the device is protected against solid objects greater than 12.5mm (like fingers) but offers no protection against water ingress. It must be installed in an enclosure.
How do I know if the surge protector has activated?
This model features an optical indicator on the device and a remote signaling contact that can be wired to an alarm system. Consult the device's manual for specific indicator details.
Can I use this protector on a TN-S or TT system?
No, this specific model is designed exclusively for TN-C systems. Using it on other system types can lead to improper protection or hazards.
What is the maximum conductor size I can connect?
You can connect a maximum conductor cross-section of 25mm² for solid or stranded conductors, and 16mm² for fine-strand flexible conductors.
What is the service life of this surge protector?
The service life depends on the number and intensity of surge events it has endured. It is recommended to replace the unit after a major surge event or if its indicators show malfunction.
Does this surge protector require maintenance?
Under normal operating conditions, the surge protector is maintenance-free. Regular visual checks are recommended.
Troubleshooting
Device not signaling status
Check the wiring of the remote signaling contact and ensure it is correctly connected to the monitoring system. Verify the surge protector itself is functioning correctly.
Overheating or unusual noise
Immediately de-energize the circuit and inspect the connections. Ensure the conductor cross-section is adequate and the ambient temperature is within the specified range. If the issue persists, replace the unit.
Device appears damaged
Do not attempt to use the device. Replace it immediately with a new unit and investigate the cause of the damage.

Setup, Compatibility & Care
Setup:
- Ensure the power supply is de-energized before installation.
- Mount the device securely onto a standard 35mm DIN rail.
- Connect the appropriate conductors (up to 25mm² rigid or 16mm² flexible) to the designated terminals, observing polarity if applicable.
- Connect the remote signaling contact wires to your monitoring system.
- Verify all connections are tight and secure.
- Restore power to the circuit.
Compatibility:
- Mains Form: Only compatible with TN-C grounded systems.
- Voltage: Designed for AC systems with a nominal voltage of 240V and a maximum continuous voltage of 350V.
- Mounting: Requires a standard 35mm DIN rail.
- Environment: Suitable for dry, protected indoor environments due to its IP20 rating.
Care:
- Regular visual inspection of connections and the device housing.
- Check the status indicator (if applicable) for normal operation.
- The device is maintenance-free under normal operating conditions. Replacement is recommended after a significant surge event or at the end of its service life.
