Frequently Asked Questions
What kind of connector is KL-400SMB?
KL-400SMB is a 400-ampere, 600 V AC/DC single-pole male panel mount receptacle (Thread-Stud Type) from the KUPO K-LOK series. Finished in blue, it belongs to the CAM-type connector family widely used across live events, film production, and temporary industrial power systems.
How much current can KL-400SMB safely carry?
KL-400SMB is designed for a maximum continuous load of 400 amperes at up to 600 V AC/DC. The brass contacts and Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C work together to maintain safe operating temperatures even under sustained full-load conditions.
How does the blue color coding on KL-400SMB help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. In North America, blue designates Phase C (L3), completing the three-phase color set. Under IEC 60446, blue is reserved for the Neutral conductor - making this color essential for international projects and cross-border equipment pools. The blue KL-400SMB connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400SMB hold?
KL-400SMB is UL / UL / cUL Listed under File Number E332947, certified to UL 1691 - the Standard for Safety for Cam-Type, Locking-Type Separable Connectors. It carries a UL Enclosure Types 3R environment rating, HB / UL94 flame classification, and full RoHS (Restriction of Hazardous Substances) compliance.
Can KL-400SMB work with connectors from other brands?
Absolutely. The K-LOK 400 A series uses the industry-standard CAM-type interface, so KL-400SMB mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
How is KL-400SMB installed in a panel or enclosure?
KL-400SMB 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.
