Product Description
Overview
KL-40FPCR is the red Santoprene TPV protective cap for a KUPO K-LOK 400 A inline female connector. The cap covers the disconnected interface and stays with the cable through a 297.5 mm lanyard assembly. It makes a red-coded cable end easy to identify during preparation, while the connector-specific fit supports NEMA 3R protection when correctly seated.
Why It Matters
A 400 A feeder connector is often moved across trucks, cable ramps, outdoor staging areas and distribution points before it is mated. Keeping the female interface covered reduces direct exposure to rain, dust and handling debris. The red body also carries the cable-identification scheme to the connector end, where crews need it during load-in and strike.
Key Features
- Female-Connector Fit: Purpose-shaped for the K-LOK 400 A inline female connector rather than used as a generic cable cover.
- Santoprene TPV Construction: Flexible, durable material rated up to 105 °C tolerates repeated fitting and removal in touring and rental workflows.
- Tethered Retention: The 297.5 mm lanyard keeps the cap with its cable assembly through setup and strike.
- Red Identification: Provides a strong visual reference for red-coded circuits and receptacle groups.
- Listed Performance: UL Enclosure Types 3R environmental rating with HB / UL94 flame class.
Applications
Intended for 400 A feeder cables used in touring power, rental inventories, generator connections, temporary distribution, industrial systems and outdoor event production.
Compatibility
Fits KUPO K-LOK 400 A inline female connectors and compatible cam-type systems with the same interface. It is not interchangeable with the male-connector cap or the smaller 150 A protective-cap family.
Frequently Asked Questions
Will the red cap change the connector's phase assignment?
No. Red is an external identification color only. Circuit function and electrical rating must be confirmed from the connector and system labeling.
What part of the connector does KL-40FPCR protect?
It covers the disconnected interface of a 400 A inline female connector, helping keep rain and debris away between connections.
Does correct fit matter for NEMA 3R protection?
Yes. The cap must match the female connector profile and seat fully. A loose, damaged or incorrect cap should not be treated as maintaining the intended protection.
Can the tether position be adjusted?
The lanyard includes a ferrule that the installer positions and crimps, allowing the cap to remain attached without interfering with normal mating.
