## Long description

The Dehn DPA M CLE RJ45B 48 is a specialized surge protection device engineered to safeguard sensitive network equipment from electrical transients. Designed for professional networking environments, this device provides robust protection for Industrial Ethernet and Power over Ethernet (PoE+) applications. Its compact, fully shielded metallic design ensures durability and effective performance in structured cabling systems, supporting data transmission speeds up to 1 Gbit Ethernet.
Advantages
This surge protection device offers comprehensive protection for all wire pairs through the use of high-performance gas discharge tubes and an integrated filter matrix. It is fully compliant with Cat. 6 standards according to ISO/IEC 11801 and supports CAT 6A in the channel as per ANSI/TIA/EIA-568. The unit is designed for easy retrofitting into existing infrastructures and features a convenient DIN rail mounting system, making it an ideal choice for maintaining signal integrity and hardware longevity in demanding industrial settings.
Suitable for
Industrial Ethernet networks
Power over Ethernet (PoE+) systems up to 57 V
Structured cabling systems
Protection of sensitive network hardware
This device may not be suitable for applications requiring protection for non-RJ45 cabling standards or environments where the nominal voltage exceeds the specified 48 V operating range. It is also not intended for use in high-voltage power distribution lines outside of standard Ethernet communication cabling.
Key specifications
Nominal input voltage: 48 V
Nominal current output: 1 A
Frequency range: Up to 250 MHz
Standards: Cat. 6 (ISO/IEC 11801), CAT 6A (ANSI/TIA/EIA-568)
Mounting: DIN rail
Housing: Fully shielded metallic finish
Weight: 123 g
Dimensions: 19 mm width, 36 mm depth
How to use
The device is designed for simple integration into existing network setups. It should be mounted onto a standard DIN rail within the cabinet or enclosure. Connect the incoming and outgoing Ethernet cables to the RJ45 ports. Ensure that the device is properly grounded using the provided earthing bracket with a flat connector sleeve to allow the surge protection mechanism to function correctly. Once installed, the device operates passively to filter and protect the data lines from electrical surges.
What to consider before purchase
Verify that your network equipment operates within the 48 V nominal voltage range.
Ensure your installation environment has access to a DIN rail for mounting.
Confirm that your cabling infrastructure utilizes RJ45 connectors.
Check that the grounding requirements can be met for optimal surge dissipation.
Usage recommendations
For maximum effectiveness, ensure the earthing bracket is connected to a low-impedance ground point. Regularly inspect the connection points to ensure they remain free of corrosion and that the DIN rail mounting remains secure.
