Frequently Asked Questions

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

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

What are the electrical ratings of KL-400SFBN?

KL-400SFBN 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 brown housing on KL-400SFBN signify?

Brown designates Phase A (L1) under IEC 60446 conventions used across Europe, the UK, Asia, and Australia. For productions touring internationally or venues hosting global acts, brown connectors ensure IEC-standard phase identification is always available. Color-coded connectors like KL-400SFBN 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-400SFBN?

KL-400SFBN 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-400SFBN commonly deployed?

You will find KL-400SFBN at work in trade shows and exhibition installations that demand professional-grade temporary power. The brown color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.

How is KL-400SFBN installed in a panel or enclosure?

KL-400SFBN mounts directly to power distribution enclosures, distro boxes, and panel assemblies using its threaded stud connection and dedicated mounting holes. Once secured, the connector provides a permanent, vibration-resistant termination point that mates with standard CAM-type inline connectors.
