FAQs
Installation requires selecting a three-pole fusible configuration within a NEMA 3R enclosure and mounting on standard electrical panels. Wire with three conductors at 240V, ensuring a fusible without neutral setup. If an auxiliary 208V circuit or a 15A GFI receptacle is used, follow the manufacturer torque specs and ensure proper grounding and labeling for safe operation.
Key specs include a 60A amperage rating, 240V operating voltage, three-pole, three-wire configuration, fusible without neutral, a NEMA 3R enclosure, Class H fuses, and UL Listing. These features support reliable fault isolation, compatibility with typical motor loads, and compliance with basic industry safety standards.
Yes. The NEMA 3R enclosure and painted galvanized steel construction provide weather resistance and durability against rain, dust, and temperature swings. This makes it a practical choice for exterior panels, wet factory floors, and other harsh environments where reliable electrical protection is critical.
The switch is UL Listed, confirming compliance with safety standards for electrical equipment. It also supports NEC 230.62 barrier compliance, ensuring safe separation for electrical installations. These certifications reduce risk, facilitate code compliance, and simplify procurement for regulated industrial projects.
The DH322FRKA1208 provides durable construction and high-interrupting-class fusing (Class H), which translates to fewer maintenance events and longer service life. The reliable isolation reduces unplanned downtime and arc-flash exposure, supporting lower lifecycle costs and faster project commissioning in manufacturing and material handling environments.
