Functional Characteristics
- Type: Compression terminal lug / splice for aluminum conductors.
- Material: Conductive aluminum alloy with low resistivity and good corrosion performance.
- Fire resistance: Non-organic metal construction supports fire-resistant use cases (verify flame/exposure rating per installation code).
- Thermal behavior: Stable contact under thermal cycling when crimped with specified dies.
- Surface: Bare aluminum (apply oxide-inhibiting compound on conductor as required by site spec).
- Applications: Switchgear, panelboards, meter/service terminations, PV combiner/inverters, industrial power drops.
-
Chemical profile: High-concern chemicals: None.

Installation & Handling
- Conductor prep (Al): Strip to length; remove oxide layer; apply aluminum-approved oxide-inhibiting compound if required.
- Crimping: Use calibrated hex or dieless dies matching the mm² size; follow die sequence for larger lugs.
- Inspection: Verify full barrel compression and conductor insertion; perform pull test per site procedure.
- Interface caution: For aluminum-to-copper terminations, use approved bi-metal pads/washers or a bimetallic lug as specified by code/equipment maker.
- Environmental: Seal as required for outdoor or corrosive locations; re-torque hardware after thermal cycling if mandated by spec.
Applications
- Power distribution panels and switchgear
- Renewable energy (PV combiner/inverter DC links)
- Industrial machinery and MCCs
- Marine and transportation electrical systems
- Aerospace/defense support equipment (weight-sensitive harnessing)
Compliance & Chemical Disclosure
- RoHS / CE: Compliant per supplier declaration.
- ISO 9001: Factory quality-management certification.
- High-concern chemicals: None reported.
Technical FAQ
Are these lugs suitable for copper busbars?
Use per equipment and code: for Al-to-Cu interfaces, employ approved bi-metal interfaces or specify a bimetallic lug to mitigate galvanic effects.
What die should I use for WKL 95 or larger?
Match the die to the mm² size stamped on the lug; large sections may specify a multi-indent/hex sequence—refer to the product datasheet/tool chart.
Do these terminals have a defined flame rating?
Listed as fire-resistant by function; consult the datasheet for any specific flame class or exposure duration applicable to your jurisdiction.
