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 400 A circuits at up to 600 V AC/DC. As a panel mount receptacle 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-400SMBK?

KL-400SMBK is rated for 400 amperes maximum continuous current at 600 V AC/DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge), 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 ( 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-400SMBK commonly deployed?

You will find KL-400SMBK at work in studio power distribution in recording, post-production, and live broadcast environments. The black color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.
