Three-pole, four-wire configuration with neutral ensures complete circuit isolation and supports four-wire 240V loads. This arrangement reduces mis-wiring risk and improves safety during commissioning and maintenance. Applications include motor control centers and industrial panels where a reliable disconnect is essential for both operation and servicing. NEMA 3R enclosure protects sensitive components from moisture, dust, and incidental impacts in outdoor and semi-exposed environments. Painted galvanized steel provides long-term corrosion resistance, reducing replacement cycles and warranty exposure. These features translate to lower lifecycle costs and predictable performance in harsh conditions. Class H fuse provision and fusible with neutral deliver selective, fast-acting overcurrent protection for both hot and neutral lines. This combination minimizes nuisance trips while safeguarding equipment during peak start-up and fault conditions. Ideal for feeders and load centers requiring neutral continuity in industrial facilities. Wire size compatibility from #6 AWG to 250 kcmil Cu/Al supports large feeders without replacing switchgear. That flexibility reduces installation time and inventory needs for diverse applications. Suitable for motors, drives, and large control circuits in manufacturing plants. 200A amperage rating paired with HP ratings up to 60 HP at 240V three-phase ensures broad applicability. Providing clear performance data aids standardization and stocking across projects. Perfect for compact switchgear and service panels in industrial facilities. UL Listed certification demonstrates compliance with recognized safety standards, while a one-year warranty from installation or 18 months from shipment adds procurement assurance. Together they offer lower risk for engineering teams and faster project timelines.

FAQs
Plan for a three-pole, four-wire setup with neutral and ensure four-wire 240V compatibility. Verify mounting clearances for a 28.12 inch height and 15.52 inch width, prepare #6 AWG to 250 kcmil Cu/Al conductors, and maintain proper line/load orientation as indicated by the enclosure markings. The NEMA 3R painted galvanized steel enclosure supports outdoor or semi-exposed environments, simplifying installation in motor control centers and outdoor panels.
Yes, the DH324NRK is rated for 240V operation with a 200A amperage rating. It provides HP ratings such as 15 HP at 240V for standard single-phase service and up to 60 HP at 240V for three-phase duty. This makes it appropriate for a range of motors and drives in industrial facilities and commercial equipment.
This switch is ideal for motor control centers, outdoor switchgear, and industrial panels requiring reliable isolation with a neutral. Its neutral-enabled fusible design accommodates four-wire 240V loads, while the NEMA 3R enclosure protects against moisture and dust, reducing maintenance interruptions in manufacturing plants and processing facilities.
The DH324NRK carries UL Listed certification, ensuring compliance with recognized safety standards. The enclosure is NEMA 3R rated, suitable for outdoor environments, and the device uses Class H fuses. These certifications support regulatory compliance, risk reduction during audits, and easier procurement for safety-conscious facilities.
The rugged galvanized steel enclosure resists corrosion, extending service life and reducing replacement costs. Neutral-enabled, three-pole design simplifies wiring and maintenance, while UL listing and a one-year warranty (or 18 months from shipment) provide post-sale support. Together, these features lower total cost of ownership and speed project timelines in industrial installations.
