Frequently Asked Questions
KL-400SMGY FAQ
What kind of connector is KL-400SMGY?
KL-400SMGY is a 400-ampere, 600V AC/DC single-pole male panel mount receptacle (Thread-Stud Type) from the KUPO K-LOK series. Finished in grey, it belongs to the CAM-type connector family widely used across live events, film production, and temporary industrial power systems.
How much current can KL-400SMGY safely carry?
KL-400SMGY is designed for a maximum continuous load of 400 amperes at up to 600V AC/DC. The brass contacts and Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius work together to maintain safe operating temperatures even under sustained full-load conditions.
How does the grey color coding on KL-400SMGY help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. Grey represents Phase C (L3) — and in some IEC applications, Neutral — under the international color code. Adding grey to the connector inventory ensures full IEC three-phase coverage alongside brown and black. The grey KL-400SMGY connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400SMGY hold?
KL-400SMGY is cRUus Listed (UL and cUL) under File Number E332947, certified to UL 1691 — the Standard for Safety for Cam-Type, Locking-Type Separable Connectors. It carries a UL Enclosure Types 3R environment rating, HB / UL94 flame classification, and full RoHS (Restriction of Hazardous Substances) compliance.
Can KL-400SMGY work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400SMGY mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
What makes KL-400SMGY suitable for permanent installations?
Unlike inline connectors designed for repeated connection and disconnection, KL-400SMGY is engineered for fixed mounting. Its threaded stud and mounting-hole pattern lock the connector firmly to the enclosure, preventing loosening under vibration — critical for touring racks and permanently installed distro systems alike.
