Product Description
Overview
The KUPO K-LOK 150 A Male Line Connector is engineered for heavy-duty reliability and safety in temporary power distribution. Featuring a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C, 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 professional entertainment and industrial applications. 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 does KL-150LMBK do and where is it typically used?
KL-150LMBK provides a safe, reliable single-pole male connection point for 150 A circuits at up to 600 V AC/DC. As a line connector with black color coding, it is commonly used in entertainment power distribution, temporary construction feeds, and industrial installations.
What are the electrical ratings of KL-150LMBK?
KL-150LMBK is rated for 150 amperes maximum continuous current at 600 V AC/DC maximum. It accepts conductors from #8 to #2 AWG (American Wire Gauge), with brass contacts delivering low-resistance connections for sustained high-current loads.
What does the black housing on KL-150LMBK signify?
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). Color-coded connectors like KL-150LMBK 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-150LMBK?
KL-150LMBK meets UL 1691 ( Cam-Type, Locking-Type Separable Connectors), is UL / UL / 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-150LMBK commonly deployed?
You will find KL-150LMBK at work in studio power distribution in recording, post-production, and live broadcast environments. The black color coding and 150-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.
What makes KL-150LMBK easy to use during fast-paced setups?
The K-LOK tool-free design means KL-150LMBK can be assembled and disassembled without specialized equipment. The ribbed Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C provides a secure grip even with work gloves, and the alignment arrow guides correct mating orientation - cutting connection time on busy sets and stages.
