The ETNRKDN400 is a robust Eaton 400A NEMA 3R breaker enclosure designed for outdoor applications. Featuring a weather-resistant construction, it provides reliable protection for circuit breakers in harsh environments. This durable enclosure ensures longevity and optimal performance, making it an ideal choice for residential and commercial electrical installations.
The ETNRKDN400 is designed for use with compatible Eaton/Cutler-Hammer breakers within the NRKDN series frame at 400A. Because breaker fitment depends on your specific frame size and configuration, we recommend sending us your breaker model number so our team can confirm a proper match before you order.
Yes. The NEMA 3R rating means this enclosure is built to withstand rain, sleet, and ice formation on the exterior — conditions common across Canadian provinces. It is appropriate for outdoor service entrance, feeder disconnect, and commercial metering applications where weatherproof protection is required.
The ETNRKDN400 is rated at 400A and is designed for both residential and commercial electrical installations where an outdoor, weather-resistant breaker enclosure is needed. Whether it qualifies as your main service disconnect will depend on your local authority having jurisdiction (AHJ) and applicable Canadian Electrical Code (CEC) requirements. We recommend confirming your application details with us or your local inspector prior to installation.
