ABB 7TCA008925R0005 Weatherproof Wire Connector - cULus
Part Number: 7TCA008925R0005
Quick Summary
Weatherproof wire connectors provide sealed terminations for outdoor electrical wiring in harsh environments. Field installations routinely contend with moisture, temperature swings, and vibration that jeopardize reliability. This ABB WP39-based connector is cULus listed, rated to 600 V and 105 °C, and uses a twist-on mounting for fast, secure terminations. Designed for wires #20 through #8, it supports efficient installation in control panels, outdoor lighting, and machinery in industrial facilities, delivering consistent performance and reduced maintenance. By pairing robust weatherproofing with clear color coding (Blue/Red) and compact packaging, it improves field productivity and helps procurement teams standardize spare part inventories.

FAQs
Install by stripping conductors to the manufacturer’s recommended length, insert the wires into the connector until fully seated, and twist to engage the seal. Ensure the correct wire range and verify a secure, moisture-tight junction. This simple, tool-free method minimizes field errors and commissioning time.
The connector supports up to 600 V and operates up to 105 °C. It accommodates wire sizes #20–#8 and is designed for weatherproof terminations in damp or outdoor environments, offering reliable performance in industrial automation applications.
Yes. Its weatherproof design and temperature/voltage ratings make it appropriate for outdoor lighting, control panels, and machinery exposed to the elements. The twist-on mechanism supports rapid field installations with durable seals to resist moisture ingress.
This connector is cULus listed, indicating compliance with safety and electrical standards for North American applications. cULus certification enhances reliability in industrial settings and supports regulator and customer compliance for outdoor installations.
Because it is weatherproof and twist-on, maintenance intervals are reduced due to fewer reseals and fewer field failures. The fast installation lowers labor costs, speeds commissioning, and simplifies spare-part inventories for service teams in automation projects.
