FAQs

What type of electrical system is this surge protector designed for?

The DEHNguard 952110 is specifically designed for TT mains systems.

What does Type 2 surge protection mean?

Type 2 surge protectors are designed to protect electrical installations and equipment from transient overvoltages, such as those caused by lightning or switching operations within the power network. They are typically installed in distribution boards.

What is the maximum surge current this device can handle?

The device has a nominal discharge surge current (8/20) rating of 20kA, meaning it can handle significant surge events.

How do I know if the surge protector is working correctly?

The DEHNguard 952110 features an optical indicator. A green or visible indicator typically signifies correct operation, while a fault indication suggests the device needs attention or replacement.

Can I install this surge protector myself?

Installation of surge protection devices should be performed by a qualified electrician to ensure safety and correct function.

What is the warranty period for this product?

The DEHNguard 952110 comes with a 2-year warranty from the date of purchase.

Does this surge protector require any special maintenance?

No, it requires minimal maintenance. However, it should be installed in a protected environment (like an electrical enclosure) due to its IP20 rating, and its status indicator should be periodically checked.

Troubleshooting

Optical indicator shows a fault or is not green

This indicates the surge arrester may have failed or is under stress. The device likely needs replacement. Consult a qualified electrician for inspection and replacement.

Device overheating or emitting unusual noise

Immediately disconnect power to the affected circuit. This could indicate a serious fault or improper installation. Contact a qualified electrician for immediate inspection.

No protection observed during a surge event

Ensure the surge arrester was correctly installed and wired according to the manufacturer's instructions. Verify that the correct model is used for the specific mains system (TT). If issues persist, consult a qualified electrician.
