Frequently Asked Questions

What does KL-400SSFO do and where is it typically used?

KL-400SSFO provides a safe, reliable single-pole female connection point for 400A circuits at up to 600V AC / 250V DC. As a panel mount receptacle with orange color coding, it is commonly used in professional entertainment power distribution, temporary construction feeds, and industrial installations.

What are the electrical ratings of KL-400SSFO?

KL-400SSFO is rated for 400 amperes maximum continuous current at 600V AC / 250V DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge; UL evaluated with 4/0 AWG), with brass contacts delivering low-resistance connections for sustained high-current loads.

What does the orange housing on KL-400SSFO signify?

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. Color-coded connectors like KL-400SSFO 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-400SSFO?

KL-400SSFO meets UL 1691 (Single Pole Locking-Type Separable Connectors), is UL Listed under UL File E332947, rated UL Enclosure Type 3R (when mated) for weather resistance, carries a UL94 HB flame rating, 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-400SSFO commonly deployed?

You will find KL-400SSFO in live event and touring power, film and broadcast production, trade shows, and industrial and emergency temporary power. The orange color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.

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

KL-400SSFO uses a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius. Santoprene TPV is chosen for its combination of rubber-like flexibility, heat resistance up to 105 degrees Celsius, and resistance to oils, chemicals, and weathering - ideal for panel mount receptacles that remain permanently installed in demanding environments.
