Frequently Asked Questions

What does KL-400SSFW do and where is it typically used?

KL-400SSFW provides a safe, reliable single-pole female connection point for 400A circuits at up to 600V AC/DC. As a panel mount receptacle with white color coding, it is commonly used in professional entertainment power distribution, temporary construction feeds, and industrial installations.

What are the electrical ratings of KL-400SSFW?

KL-400SSFW is rated for 400 amperes maximum continuous current at 600V AC/DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge), with brass contacts delivering low-resistance connections for sustained high-current loads.

What does the white housing on KL-400SSFW signify?

White is universally recognized in North America as the Neutral conductor per NEC conventions. Using a dedicated white connector for neutral runs eliminates guesswork during setup and teardown, reducing the risk of miswired circuits. Color-coded connectors like KL-400SSFW allow crews to visually verify correct phase wiring at a glance, which is especially valuable during fast-paced load-ins and load-outs.

What safety standards apply to KL-400SSFW?

KL-400SSFW meets UL 1691 (Cam-Type, Locking-Type Separable Connectors), is cUL Listed under E332947, rated UL Enclosure Types 3R for weather resistance, carries a HB / UL94 flame class, and complies with RoHS hazardous substance restrictions. These certifications collectively ensure the connector is safe for professional use in entertainment and industrial environments.

Where is KL-400SSFW commonly deployed?

You will find KL-400SSFW at work in studio power distribution in recording, post-production, and live broadcast environments. The white color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.

What is the advantage of the double set screw design on KL-400SSFW?

The double set screw termination on KL-400SSFW provides redundant cable clamping - each screw independently secures the conductor, adding a layer of safety against vibration-induced loosening. This is particularly valuable in touring rigs and mobile power systems where connectors experience constant mechanical stress.
