Eaton DH324NDKLW Heavy Duty Fusible Safety Switch - UL Listed
Part Number: DH324NDKLW
Quick Summary
Eaton DH324NDKLW heavy duty fusible safety switch provides reliable motor control for industrial equipment. Maintenance teams often face unplanned downtime and unsafe isolation during service; this switch delivers a clear viewing window, resilient galvanized enclosure, and field-modification options to meet rainproof requirements. It carries UL Listed certification and NEC 230.62 (C) compliant barrier, reinforcing regulatory compliance in critical facilities. Designed for 200 A at 240 V, three-pole operation with neutral, it supports up to 60/40 hp (1-phase/3-phase) and accommodates large conductors (#6-300 kcmil Cu/Al). With NEMA 12/3R protection and a factory-supported path to NEMA 3R rainproof capability, the DH324NDKLW reduces downtime, improves safety, and lowers lifecycle costs for panel builders and OEMs.

Selling Policy 25-000 - Distribution and Control Products and Services
Enclosure and durability drive uptime. The DH324NDKLW uses painted galvanized steel housed in a NEMA 12, NEMA 3R enclosure with a lower viewing window. This protects against dust and incidental moisture while allowing quick status checks in busy plant areas, improving maintenance efficiency and reducing unplanned outages in conveyors and machine tool lines. 200 A protection and flexible wiring enable safe, scalable control. The unit is rated at 240 V, three-pole with neutral and four conductors (#6-300 kcmil Cu/Al), supporting large motor loads up to 60/40 hp. For manufacturers, that means fewer devices and simpler panel design while meeting motor starter requirements in packaging, metals, and processing lines. Fusible with neutral Class H fuse provides controlled disconnection for safe maintenance and energy management, expanding reliability and safety for rugged operations. The catalog notes 2-pole applications using the outside poles of a 3-pole switch, with field modification to meet NEMA 3R rainproof requirements when a drain hole is opened, broadening installation options for outdoor or damp environments. Compatibility and warranty support are strong points: a 25-000 policy offers confidence, while NEC barrier compliance reduces regulatory risk on safety-critical lines. The overall design minimizes lifecycle costs for OEMs and panel builders through durable construction and straightforward service.

FAQs
The DH324NDKLW is designed with a NEMA 12/3R enclosure and can be field modified to meet rainproof requirements by opening a factory provided drain hole. For 2-pole applications, use the outside poles of a 3-pole switch. Ensure proper enclosure sealing after modification and verify that the integrity of the rating remains suitable for the installation environment.
This switch provides 200 A amperage at 240 V, with three poles and a neutral, four conductors total. It accommodates conductor sizes from #6 to 300 kcmil for copper or aluminum. HP ratings reach up to 60/40 hp (1-phase/3-phase, Std/TD at 250 Vdc), enabling substantial motor loads in industrial applications.
Yes. The painted galvanized steel enclosure rated for NEMA 12 and NEMA 3R, combined with a lower viewing window and UL Listed certification, makes it suitable for packaging lines, conveyors, and machine tools. Its durable construction and fusion of neutral wiring support reliable operation in environments with dust, moisture, or incidental exposure.
The device is UL Listed and carries NEC 230.62 (C) compliant barrier protection, supporting compliance in safety-critical industrial facilities. Its NEMA 12/3R enclosure also aligns with typical industrial protection requirements, while the field-modifiable rainproof capability expands permissible installation scenarios under environmental standards.
Eaton provides a warranty per Selling Policy 25-000: one year from the date of installation or eighteen months from shipment, whichever comes first. This coverage supports limited downtime risk and ensures assistance with product reliability, field support, and replacement considerations in busy manufacturing environments.
