FAQs
The DH324FRK is a three-pole, 200A switch designed for service entrances. It uses a 240V three-wire configuration and is compatible with #6 AWG to 250 kcmil Cu/Al conductors. Plan for a NEMA 3R enclosure and ensure Neutral Kit compatibility if service entrance neutral is required. Mounting should follow standard electrical codes, with proper clearance for safe access during maintenance.
This unit supports #6 AWG through 250 kcmil Cu/Al conductors, enabling direct connections from feeders to the switch. It is configured as a three-pole, three-wire device rated for 200A at 240V. When wiring, observe proper torque values, insulation integrity, and the neutral-kit requirements if neutral is used in the circuit.
Yes. The enclosure is NEMA 3R rated and finished in painted galvanized steel, providing weather resistance suitable for outdoor or semi-exposed environments. This makes it appropriate for service entrances and outdoor equipment enclosures, helping to reduce corrosion-related maintenance and downtime.
The DH324FRK carries UL Listed certification and comes with Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever is sooner. Regular inspections should verify fuse integrity, clean enclosure surfaces, and confirm secure terminations. Maintain clear access and replace fusible elements as recommended by Eaton’s datasheets to sustain reliability.
Common applications include service entrances, motor control and large feeder circuits in manufacturing facilities. Benefits include reliable fault isolation, reduced downtime due to quick disconnect capability, enhanced safety during maintenance, and compliance with UL standards and NEMA 3R environmental protection. Its fuse class H and non-neutral fusible configuration support flexible, code-compliant protection for three-wire systems.
