Product Description
Overview
KL-DCB2 is the blue snap-back dust cover for a 150 A cam-type receptacle. Its high-impact, flame-retardant ABS body closes over the unused receptacle, while a gasket and corrosion-resistant stainless-steel hardware support NEMA 3R environmental protection. The blue lid helps crews trace a designated receptacle group during setup.
Why It Matters
An open panel receptacle can collect rain, dust and handling debris long before a cable is connected. This cover gives the 150 A receptacle a dedicated closure that opens with the cable connection and snaps back into place afterward. The blue finish also keeps identification visible at the panel rather than only on the cable.
Key Features
- Snap-Back Protection: The lid remains attached to the panel and returns over the receptacle after cable removal.
- NEMA 3R Seal: A supplied gasket helps protect the unused receptacle from falling rain and environmental exposure.
- Durable Construction: Flame-retardant ABS and stainless-steel hardware suit repeated operation on portable distribution equipment.
- Blue Identification: Supports quick recognition of blue-coded power assemblies.
- Listed Performance: UL Enclosure Types 3R environmental rating with HB / UL94 flame class.
Applications
Designed for 150 A cam-type receptacles on touring distros, generator panels, rental power equipment, industrial enclosures and temporary event-power systems.
Compatibility
Fits compatible 150 A cam-type panel receptacles using the listed three-hole, 120° mounting pattern. Verify flange dimensions and panel clearance before installation; it is not interchangeable with the larger 400 A KL-DC cover.
Frequently Asked Questions
How does the snap-back action help on a busy distribution panel?
The lid stays part of the mounted assembly, opens for the cable connection and returns over the receptacle when the connection is removed. Crews do not have to manage a separate loose cap.
Is KL-DCB2 for a 150 A or 400 A receptacle?
KL-DCB2 is the blue cover for the 150 A cam-type receptacle. The corresponding 400 A family omits the final 2 from the SKU.
What should be checked before relying on NEMA 3R protection?
Verify the gasket is present, the flange is secured evenly through all three holes, and the lid closes fully without damage or obstruction.
Can blue be used as a circuit identifier?
Yes, as part of a documented site or rental-house color plan. Color alone should never replace electrical labeling or testing.
