Frequently Asked Questions
What does KL-400SMBK do and where is it typically used?
KL-400SMBK provides a safe, reliable single-pole male connection point for 400A circuits at up to 600V AC / 250V DC. As a panel mount receptacle with black color coding, it is commonly used in professional entertainment power distribution, temporary construction feeds, and industrial installations.
What are the electrical ratings of KL-400SMBK?
KL-400SMBK 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 black housing on KL-400SMBK 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-400SMBK 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-400SMBK?
KL-400SMBK 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-400SMBK commonly deployed?
You will find KL-400SMBK in live event and touring power, film and broadcast production, trade shows, and industrial and emergency temporary power. The black color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.
