Product Description
The KUPO K-LOK 400A Male Line Connector is engineered for heavy-duty reliability and safety in high-current temporary power distribution. Featuring a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius, brass contacts for superior conductivity, and a non-conductive POM (Polyoxymethylene) retaining screw that eliminates accidental current paths, this connector delivers the mechanical strength and electrical performance demanded by large-scale entertainment productions and industrial applications handling up to 400 amperes. The modular, tool-free design enables rapid field assembly and disassembly, while full interoperability with standard CAM-type connectors ensures seamless integration into existing power distribution systems.

Frequently Asked Questions
What kind of connector is KL-400LMBK?
KL-400LMBK is a 400-ampere, 600V AC/DC single-pole male inline cable connector from the KUPO K-LOK series. Finished in black, 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-400LMBK safely carry?
KL-400LMBK is designed for a maximum continuous load of 400 amperes at up to 600V AC/DC. The brass contacts and Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius work together to maintain safe operating temperatures even under sustained full-load conditions.
How does the black color coding on KL-400LMBK help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. Under North American NEMA/NEC conventions, black identifies Phase A (L1), making it the go-to choice for single-phase circuits and the default lead in three-phase systems. In IEC regions, black denotes Phase B (L2). The black KL-400LMBK connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400LMBK hold?
KL-400LMBK is 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-400LMBK work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400LMBK mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
What makes KL-400LMBK easy to use during fast-paced setups?
The K-LOK tool-free design means KL-400LMBK can be assembled and disassembled without specialized equipment. The ribbed Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius provides a secure grip even with work gloves, and the alignment arrow guides correct mating orientation - cutting connection time on busy sets and stages.
