The DEHN Surge Arrester - DRL 10 B 180 FSD is designed for protecting data and M&R applications from power surges and lightning strikes. It offers robust protection for sensitive electronic equipment, ensuring operational continuity. A key caveat is that its visual indicator is the primary method of status signaling, requiring periodic checks.

Its primary function is to protect data and M&R (Measurement & Registration) applications from transient overvoltages caused by lightning or power system switching, safeguarding sensitive electronic equipment.
The device features a visual fault indicator on the gas discharge tubes. A change in color indicates a fault or that the protection element has operated and requires replacement.
Yes, the integrated disconnection block contacts allow for testing, measuring, and patching of the lines without needing to remove the protection plug.
It has a nominal discharge current (8/20 µs) of 10kA and a lightning impulse current (10/350 µs) of 5kA. The nominal load current is limited to 0.4A.
Yes, the device can be upgraded to a combined lightning and surge arrester by using a compatible DRL protective plug.
It uses the LSA-Plus plug-in mounting method for its connection.
The nominal voltage is DC 180V. The maximum continuous voltage is AC 127V and DC 180V.
The visual fault indicator signifies that the gas discharge tube has operated or is faulty. The protection element needs to be replaced. Ensure power is disconnected before attempting replacement.
Verify that the surge protector is correctly installed and all connections are secure. Check if the visual indicator shows a fault. If the indicator is normal, inspect the upstream and downstream cabling for damage. Test the line by using the integrated disconnection block to patch through the connection without the protection element; if the issue resolves, the arrester may be faulty or the surge conditions are exceeding its capacity.
Ensure you are using a compatible LSA-Plus interface and that the slot is clear of debris. Confirm the device model is designed for LSA-Plus termination.
Setup: The DEHN Surge Arrester - DRL 10 B 180 FSD is designed for LSA-Plus connection systems. Installation involves terminating the incoming data lines onto the LSA-Plus block and then plugging the surge protection device into its designated slot. Ensure proper grounding is established as per local electrical codes.
Compatibility: This device is specifically designed for dataline protection with LSA-Plus interfaces. It is compatible with systems operating at a nominal voltage of DC 180V and a maximum continuous AC voltage of 127V or DC voltage of 180V. It is suitable for applications with a nominal load current of up to 0.4A.
Care: Regular visual inspection of the status indicator is recommended to ensure the device is functioning correctly. The color change indicates a fault, necessitating replacement. Beyond visual checks, no specific maintenance is typically required for the arrester itself, assuming proper initial installation. The integrated disconnection block allows for testing and patching, which can be part of routine system checks.
