Multiquip EE57530 NEMA 3R Circuit Breaker Enclosure

The Multiquip EE57530 is a genuine OEM NEMA 3R Circuit Breaker Enclosure designed for Multiquip ultra-silent diesel generator models including the DCA25USI4CAN, DCA45USI4CAN, and DCA70SSJU4i. As a factory-sourced component, this enclosure is manufactured to the exact dimensional and material standards required for proper fit and safe electrical isolation within these generator units. Verify your model code against the confirmed fitment list — including Canadian-market variants of the DCA25USI4CAN and DCA45USI4CAN — before ordering to ensure compatibility.

Key Features

• NEMA 3R Rated Protection — Engineered to shield the circuit breaker from rain, sleet, and external water ingress, maintaining electrical integrity in outdoor generator applications.
• Genuine OEM Component — Sourced directly from Multiquip, this enclosure meets the same material and construction standards as the original unit installed at the factory.
• Direct-Fit Replacement — Designed to mount in the existing enclosure location on DCA25USI4CAN, DCA45USI4CAN, and DCA70SSJU4i generators, including French-Canadian (FR) variants, with no modification to surrounding hardware.
• Electrical System Integrity — A properly sealed enclosure keeps moisture and contaminants away from the circuit breaker contacts, preventing nuisance trips, corrosion, and potential arc faults during generator operation.
• Safety-Critical Enclosure — Circuit breaker enclosures are a key layer of protection in generator electrical systems; using the correct OEM-rated housing ensures compliance with the design intent of the machine's electrical protection scheme.

The circuit breaker enclosure serves as the protective housing for the generator's circuit breaker, shielding it from environmental exposure while keeping internal electrical connections secure and accessible for service. A NEMA 3R rating specifically indicates the enclosure is built to resist rain and ice formation on the exterior — an important attribute for generators operating on outdoor worksites. When an enclosure is cracked, warped, or missing its seal, moisture can reach the breaker contacts, leading to corrosion, intermittent faults, or unsafe electrical conditions that compromise both equipment performance and operator safety.
