Arrow Hart - Connecting Safety to Reliability since 1890
Eaton Specification Sheet - CWL1420CBK-BU
The ultra grip locking mechanism provides a secure, vibration-resistant connection that minimizes unplanned outages in motors, conveyors, and control panels, translating to improved equipment uptime and reduced service calls. The nylon body and face promote durability in harsh environments, with wide operating temperatures (-40 to 60 °C) that support both indoor and outdoor installations without sacrificing performance. Back wiring simplifies on-site wiring, enabling faster panel builds and cleaner terminations, which reduces labor time and wiring errors during installation. With a 20A, 125/250V rating and L14-20 NEMA configuration, this connector handles standard industrial loads while maintaining safe, compliant power distribution for three-pole, four-wire systems. The bulk pack of 50 delivers cost-effective stocking for distributors, OEMs, and maintenance teams, lowering unit cost per connection and ensuring readily available replacements. Robust certifications and the extra heavy-duty construction address common compliance concerns in regulated facilities, supporting consistent audits and traceability for industrial projects.

FAQs
The CWL1420CBK-BU uses a back-wiring method, allowing conductors to be terminated from the rear of the connector. This simplifies field installation, improves termination consistency, and reduces the risk of strand damage during assembly in control panels and rugged equipment enclosures.
Yes. The connector specifies an allowable wire size of #16-8 AWG, enabling a broad range of common control and power conductors while maintaining the integrity of the locking mechanism and electrical performance in industrial settings.
The CWL1420CBK-BU is configured as an L14-20, three-pole, four-wire locking connector rated for 20A at 125/250V. This makes it suitable for high-current, non-noticeable miswiring scenarios typical in motors and industrial control circuits.
This connector is RoHS Compliant and cULus Listed NOM. RoHS ensures restricted substances limits are met for safer, environmentally responsible use, while cULus listing confirms conformance to recognized safety standards, helping with regulatory compliance and safety audits in manufacturing facilities.
Bulk packaging reduces procurement overhead, lowers per-unit pricing, and ensures readily available replacements for maintenance crews and original equipment manufacturers. It also simplifies stocking in service vans, warehouses, and panel assembly operations, improving uptime and reducing downtime related to part shortages.
