KD frame design and three‑pole construction enable flexible deployment in medium‑sized feeders and panelboards, with a clear path to reliable protection in hazardous locations. This translates to fewer panel modifications, quicker commissioning, and improved uptime in oil & gas, chemical processing, and mining facilities. The explosionproof enclosure, constructed from copper‑free aluminum with a bolted/ground joint and gasketed cover, reduces corrosion risk and enhances worker safety in aggressive environments while meeting classification requirements. The 600 Vac/250 Vdc rating supports mixed supply scenarios, and the 100–400 A amperage range provides scalable protection for feeders and distribution circuits, with a 200 A trip option visible in field settings for predictable fault clearing. Industry‑leading certifications, including NEC/CEC standards and NEMA ratings 3, 3R, 4, 7, 9, 12, help ensure regulatory compliance and ease of procurement for projects demanding stringent hazard protections. Its dimensions and weight (20.28 in L × 42.65 in H × 10.92 in W, ~328 lb) fit standard installation footprints, reducing the need for custom enclosures and accelerating installation timelines. Compatibility with existing KD frame systems and Eaton Crouse‑Hinds catalog pages further streamline sourcing and maintenance, while practical installation features like gasketed covers support weatherproofing and quick replacement after service. The unit’s 3‑pole construction, with a robust 400 A frame, is well suited for high‑demand motor protection and feeder protection in harsh environments, aligning with industry best practices for hazardous location installations and reducing total cost of ownership over the equipment lifecycle.

FAQs
Yes. The EBMBK WT200KD36 uses the KD frame type and is designed for hazardous locations, including Class I Division 1 and Class I Division 2, with compatible mounting and enclosure interfaces. When installing, ensure enclosure rating and wiring practices meet local codes and the equipment’s gasketed, bolted cover design for a reliable seal.
The breaker is rated for 600 Vac and 250 Vdc, with an amperage range of 100 A through 400 A and a three‑pole configuration. Its 400 A frame size supports higher‑load feeders, while the 200 A trip reference (as indicated in the product description) provides a baseline protection threshold for coordinated protection schemes.
Industries such as oil and gas, chemical processing, mining, and other heavy‑industrial facilities rely on EBMBK WT200KD36 for explosionproof protection in hazardous or classified locations. The unit’s combination of robust enclosure, high frame rating, and NEC/CEC compliance makes it suitable for critical power distribution feeders in harsh environments.
The EBMBK WT200KD36 carries NEC/CEC standards compliance and NEC hazardous ratings across Class I Division 1 and Division 2, Class II Division 1 and Division 2, and Class III. It also aligns with NEMA ratings 3, 3R, 4, 7, 9, 12, ensuring broad suitability for outdoor and industrial installations in hazardous locations.
Maintenance focuses on periodic inspection of the gasketed enclosure, bolted joints, and the integrity of the copper‑free aluminum housing to prevent corrosion and seal wear. ROI is driven by improved safety, reduced risk of process interruptions, and longer service life in harsh environments, along with simplified sourcing through KD frame compatibility and Eaton’s catalog support.
