The DEHN 941300 is a Type 1+2 combined arrester designed for energy technology applications using a TN-C network structure. It offers robust protection against surges, including direct lightning strikes, for low-voltage consumer installations. A key benefit is its compact, space-saving design utilizing spark-gap technology. However, it requires a TN-C system configuration and is primarily intended for static applications.

The DEHN 941300 is specifically designed for and compatible with TN-C (combined neutral and protective earth) power supply systems.
It can handle a lightning impulse current of 37.5 kA (10/350 µs), providing robust protection against severe surge events.
The device features an optical indicator that signals its operational status. Refer to the product manual for specific indicator meanings. If the indicator shows a fault, replacement is necessary.
The voltage protection level is 1.5 kV for both L-N (Line-to-Neutral) and L-PE (Line-to-Protective Earth) connections.
No, the DEHN 941300 is exclusively designed for TN-C systems and is not suitable for TT or TN-S configurations.
The maximum conductor cross-section for solid or stranded conductors is 35mm², and for fine-strand flexible conductors, it is 25mm².
The DEHN 941300 is designed to be maintenance-free. However, the optical indicator should be periodically checked for status.
The arrester may have failed due to a surge event. It is no longer providing protection and needs to be replaced by a qualified electrician.
Ensure you are using a standard 35 mm DIN rail and that the mounting clips on the arrester are correctly engaged. Check for any obstructions on the rail.
This is not a normal condition. Disconnect power immediately and have the installation inspected by a qualified electrician to check for wiring issues or device failure.
Setup: The DEHN 941300 is designed for mounting on a 35 mm DIN rail (top hat rail). It requires installation by a qualified electrician. Ensure the device is connected according to the TN-C system configuration specified in the technical documentation. The maximum conductor cross-section for solid or stranded conductors is 35mm², and for fine-strand flexible conductors, it is 25mm².
Compatibility: This arrester is specifically compatible with TN-C power supply systems. It is not compatible with TN-S, TT, or IT systems. Ensure your installation adheres to the system configuration requirements before installation.
Care: The DEHN 941300 is a maintenance-free device. It features optical signaling directly on the device to indicate its status. Regularly check the optical indicator to ensure the arrester is functioning correctly. In case of malfunction indicated by the visual signal, the unit should be replaced by a qualified professional. Do not attempt to open or repair the device. Keep the area around the installation clean and free from dust and debris.
