CLA - Compact Lighting Arrester

Product catalog summary

Compliance Standards: The Compact Lightning Arrestor (CLA) complies with international standards including ICAO (Aerodrome design manual, part 5), IEC (IEC99-4 and 61822 / § 5.7.4), and FAA (AC150/5345-10E / § 3.4.10 and AC150/5345-26C).

Applications: The CLA series is designed for airfield lighting applications on runways, taxiways, or aprons, providing protection against overvoltages and surges from both external (atmospheric influences, static loads, lightning) and internal (electrical stability modifications, switching oscillations, electric arcing, ground faults) sources.

Advantages: The CLA offers a large security margin between ignition and insulation levels, ensuring no risk of incorrect operation. It is easy to maintain and can be integrated into existing installations due to its standard male/female plug compliant with IEC and FAA standards. In case of failure, the device can be easily disconnected and replaced.

Internal Constitution: The active part of the CLA consists of non-linear resistors (varistors) made of zinc oxide, protected by a stratified glass-epoxy cover and molded with polyurethane. The earthing terminal is a brass stud M12.

Design: The CLA is compact and identified by an ordering code indicating its type and capacity, such as CLA-30 for loops between 20 and 30kVA.

Performances: The CLA has a protection index of IP68, operates in temperatures from -40°C to +60°C, and weighs approximately 5kg. It features an M12 earthing stud, a cable diameter of 10.2mm, and a T style, L823 Type 1 Class A plug.

Electrical Features: The CLA models (CLA-10, CLA-20, CLA-30) have varying permanent operation voltages (2.55 kV, 5.10 kV, 7.65 kV), nominal voltages (3 kV, 6 kV, 9 kV), acceptable overvoltages (3.4 kV, 6.8 kV, 10.2 kV), and residual voltages (9 kV, 19 kV, 29 kV). All models have a nominal discharge current of 10 kA and a maximum surge current of 65 kA.

Marking: The bottom of the molding is engraved with the model (CLA-10 to 30), nominal voltage (3 to 9kV), and nominal current (10 kA).

Certification: Augier is ISO 9001 certified since 1995.
