## Summary description

The DEHN DBX U4 KT BD S 0-180 is a grey surge protection device designed for nominal input voltage of 180 V. It weighs 220 g and has dimensions of 93 mm x 93 mm. This device provides reliable protection against voltage spikes, ensuring the safety and longevity of connected equipment.

## Long description

The DEHN DBX U4 KT BD S 0-180 is a compact combined lightning current and surge arrester in a surface-mounted plastic enclosure. It is designed to protect two pairs of galvanically isolated balanced interfaces with the same or different signal voltages and supports direct or indirect shield earthing. The unit incorporates actiVsense technology and is intended for installation at lightning protection zone boundaries from 0A–2 and higher.
Advantages
This compact surge protection device is capable of carrying lightning currents up to 10 kA (10/350 µs) while providing a low voltage protection level suitable for safeguarding terminal equipment. Its IP65-rated surface-mounted plastic enclosure allows wall mounting and offers environmental protection. Spring-loaded terminals enable quick and easy installation and reliable contact even in confined installations.
Suitable for
 Protection of two-pair balanced data or signal transmission lines (galvanically isolated)
 Installations requiring combined lightning current and surge protection at LPZ boundaries (0A–2 and higher)
 Applications with direct or indirect shield earthing requirements
 Indoor or sheltered outdoor wall-mounted equipment where IP65 protection is needed
When it may not be suitable
This device is intended for protecting balanced interfaces and may not be suitable for unbalanced single-conductor signals or for circuits requiring different protection concepts (for example, specialized mains surge protection or protection for high-frequency radio antennas). It is also not a substitute for full structural lightning protection systems where additional measures are required.
Key specifications
 Function: combined lightning current and surge arrester for two pairs
 Lightning current capability: up to 10 kA (10/350 µs)
 Nominal voltage (recommended application): 180 V
 Enclosure: surface-mounted plastic, degree of protection IP65
 Connection: spring-loaded terminals for quick installation
 Dimensions: 93 mm × 93 mm × 54 mm
 Weight: 220 g
 Shield earthing: supports direct or indirect earthing
How to use
Mount the device on a suitable wall surface ensuring correct orientation and secure fastening. Connect the two balanced signal pairs to the designated terminals, observing polarity and maintaining galvanic isolation as required by the installation. Implement shield earthing either directly or indirectly, following site earthing practices and local standards. Verify connections before restoring operational voltage and test the protected equipment after installation.
What to consider before purchase
 Ensure the device's nominal voltage (about 180 V) matches the signal system requirements
 Confirm the need for combined lightning current and surge protection for balanced two-pair lines
 Check available mounting space to accommodate the unit's dimensions (93 × 93 × 54 mm)
 Verify that IP65 enclosure rating and spring-loaded terminal terminations meet environmental and installation needs
Usage recommendations
Install this surge protection device at the appropriate lightning protection zone boundary and follow national installation standards and the manufacturer's detailed instructions. Periodically inspect the device and connections after significant surge events and during routine maintenance to ensure continued protection.
