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 / 250V 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 / 250V DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge; UL evaluated with 4/0 AWG), 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 the IEC 60445 color code used across Europe, the UK and much of Asia. 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 (Single Pole Locking-Type Separable Connectors), is UL Listed under UL File E332947, rated UL Enclosure Type 3R (when mated) for weather resistance, carries a UL94 HB flame rating, 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 in live event and touring power, film and broadcast production, trade shows, and industrial and emergency 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.
