Frequently Asked Questions

Who should use KL-400SMO and why?

Lighting technicians, electricians, and power distribution professionals working with 400A temporary power systems will benefit from KL-400SMO. Its orange 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-400SMO rated for?

KL-400SMO 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 orange version of the K-LOK 400A male panel mount inlet?

Orange is traditionally reserved for high-leg delta circuits and other specialty applications in North America. It provides an unmistakable visual warning that a conductor carries a voltage different from the standard phases - critical information for electricians working with delta transformer configurations. Choosing KL-400SMO in orange ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.

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

Yes. KL-400SMO 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-400SMO?

KL-400SMO 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 orange phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.

What housing material is used in KL-400SMO and why does it matter?

KL-400SMO uses a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius. Santoprene TPV delivers outstanding resistance to heat, chemicals, and UV exposure while maintaining flexibility across a wide temperature range - essential properties for connectors installed in enclosures that may face extreme operating environments.
