Product Description
Overview
KL-DCB is the blue weatherproof snap-back cover for a compatible 400 A cam-type panel receptacle. A high-impact, flame-retardant ABS body, corrosion-resistant stainless-steel hardware and a supplied gasket form a durable closure for the unused receptacle. The standard 57.3 mm square frame supports retrofit installation, and the blue lid helps crews trace blue-coded receptacles across a distribution panel.
Why It Matters
Panel receptacles may remain exposed through outdoor staging, transport and long periods between connections. The hinged lid stays attached to the enclosure and closes over the receptacle as soon as the feeder is removed, helping exclude falling rain, dust and debris. The blue finish keeps the circuit-identification cue visible directly at the connection point.
Key Features

Frequently Asked Questions
How does the snap-back lid help during changeovers?
The cover stays mounted to the panel, opens for the feeder connection and returns over the receptacle after disconnection, so no loose cap has to be stored.
Which mounting pattern should be prepared for KL-DCB?
Prepare four 6.5 mm fixing holes on 38 x 38 mm centers for the 57.3 x 57.3 mm frame.
Why is flame-retardant ABS used for the blue lid?
ABS provides impact resistance for repeated field handling, while the flame-retardant formulation suits power-distribution equipment.
What opening and lid diameters are shown for KL-DCB?
The catalog drawing lists a 45 mm inner opening and a 53 mm lid diameter.
