Eaton EBMBK WT400KD36 Explosionproof KD 400A

Explosionproof KD-frame design with a three-pole construction delivers intrinsic protection for arc quenching and enclosure sealing in hazardous locations, reducing ignition risk and downtime. This rugged architecture is particularly valuable in chemical plants, oil and gas facilities, and mining sites where safety-critical protection is required. Voltage and amperage versatility with 600 Vac/250 Vdc ratings and a 400A frame, with an adjustable 100–400 A range, enables single-device protection for feeders and motor circuits, reducing panel footprint and maintenance complexity. It is well-suited for main distribution and motor control centers that demand robust protection in hazardous environments. Copper-free aluminum enclosure offers durability with lower weight and improved corrosion resistance, translating to easier handling during installation and fewer maintenance concerns in damp or corrosive environments, such as offshore platforms or chemical processing plants, where material compatibility matters. Bolted/ground joint with gasketed cover construction provides superior sealing against dust and moisture, accelerating serviceability and reducing ingress-related failures. The design supports long-life operation in rugged installations and simplifies field retrofits or expansions. Three-pole, 400A frame and 600 Vac/250 Vdc capability deliver flexible protection for large feeders and motor loads, reducing the need for multiple devices. Combined with NEC/CEC compliance and NEMA 3/3R/4/7/9/12 compatibility, it streamlines procurement, installation, and conformity across facilities. Certification and standards alignment ensures NEC/CEC compliance with Hazardous/Classified Locations ratings, including Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III, supported by UL-based Canadian certifications and a broad NEMA compatibility profile. This minimizes risk during audits and helps maintain ongoing regulatory adherence.
