FAQs
Retrofitting this switch into existing panels requires matching the 3-pole, single-throw configuration with a compatible NEMA 12 enclosure. Ensure the panel space accommodates the 13.25 in width, 25.5 in height, and 9 in depth, and verify the system runs at 600 V with a 100 A rating. Also confirm NEC 230.62 barrier integration for compliant safety separation.
Performance is defined by a three-pole, 100 A, 600 V fusible design suitable for motor control centers and machine disconnects. The NEMA 12 enclosure provides dust protection, while the fusible configuration helps protect circuits from overloads. UL 98 listing adds safety assurance, ensuring reliable isolation during motor startups and routine maintenance.
Yes. The DH363FDK2YEL is UL 98 listed and designed to meet NEC 230.62 barrier requirements. These certifications support safe installation in industrial facilities, enhance regulatory compliance, and simplify safety inspections. It also employs a NEMA 12 enclosure suitable for typical indoor industrial environments.
Absolutely. The NEMA 12 enclosure offers protection against dust and non-watery ingress common in factory settings. While not rated for direct water exposure, it is well-suited for electrical rooms, controlled machine bays, and indoor production areas where dust and particulate matter are present, helping maintain switch integrity and reliability.
Maintenance centers on inspecting fuse status and preparing for fuse replacement without neutral, as specified by the fusible configuration. Stock compatible 100 A fuses and follow lockout/tagout procedures during replacement. The UL 98 listing and robust NEMA 12 enclosure support safe, compliant maintenance with predictable downtime and minimal risk to personnel.
