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 design enables rapid field assembly and disassembly, while full interoperability with standard CAM-type connectors ensures seamless integration into existing power distribution systems.

Key Features

  • Non-conductive POM (Polyoxymethylene) retaining screw locks the brass contact firmly in position, eliminating accidental current paths for safer operation
  • POM insulation sleeve adds heat resistance and structural strength to the contact assembly
  • Ribbed Santoprene TPV housing provides a secure, slip-free grip even when wearing work gloves
  • Alignment arrow ensures correct orientation for fast, error-free mating every time
  • Santoprene TPV housing rated to 105 degrees Celsius withstands demanding site conditions and extreme temperatures
  • Brass contacts deliver reliable, low-resistance electrical connections for sustained high-current loads up to 400A
  • Double set screw termination accommodates #6 AWG (American Wire Gauge) to 4/0 AWG conductors with redundant cable retention

Frequently Asked Questions

Who should use KL-400LMBN and why?

Lighting technicians, electricians, and power distribution professionals working with 400A temporary power systems will benefit from KL-400LMBN. Its brown housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius ensures durability in demanding field conditions.

What voltage and amperage is KL-400LMBN rated for?

KL-400LMBN carries a maximum rating of 400A and 600V AC / 250V DC. It accepts wire gauges from #6 to 4/0 AWG (UL evaluated with 4/0 AWG), making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.

Why choose the brown version of the K-LOK 400A male line connector?

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. Choosing KL-400LMBN in brown ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.

Is KL-400LMBN UL listed and what does that mean?

Yes. KL-400LMBN is UL Listed under UL File Number E332947, meaning UL has independently tested and certified it to UL 1691 for the United States. The listing covers the United States.

What industries commonly use KL-400LMBN?

KL-400LMBN is used across live events and touring, film and broadcast, rental and staging inventories, and industrial temporary power. Its 400A / 600V AC / 250V DC rating, combined with CAM-type universal compatibility and brown phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.

How do you assemble KL-400LMBN in the field?

KL-400LMBN features a modular design that enables rapid assembly and disassembly on site. Strip the cable, insert it through the housing, secure it with the double set screw termination, and lock the brass contact in place with the non-conductive POM retaining screw. The alignment arrow ensures correct orientation every time.
