Eaton DH326FRKV Heavy Duty Fusible Safety Switch - UL

600 A amperage rating paired with a three‑pole, three‑wire configuration translates into immediate protection for large, critical loads and a simplified protection scheme for upstream feeders. The Class H fuse provision delivers fast fault clearance while maintaining selectivity, reducing arc flash exposure and minimizing collateral damage during faults. For industrial facilities, the DH326FRKV supports heavy motor drives with a max coverage of 75 HP standard and 200 HP when TD conditions apply, offering a scalable disconnect for diverse applications. Enclosure and durability: The NEMA 3R enclosure, built from painted galvanized steel, provides weather resistance suitable for outdoor and damp environments. This integration reduces the need for ancillary housings and speeds installation, while preserving corrosion resistance in challenging plant conditions. With UL listing and NEC barrier compatibility, end users gain a safer, code-compliant solution that stays reliable across shifts and seasons. Enhanced visible blade: The visible blade feature supports quick status checks during commissioning and routine maintenance, cutting diagnostic time and improving fault identification accuracy. Combined with a rugged fusible design, it helps maintenance teams verify operability before testing live circuits, aligning with best practices for safe equipment isolation. This translates into lower downtime and more predictable maintenance windows in manufacturing environments. Reliability and compliance: UL Listed certification reinforces safety expectations, while the NEC 230.62 barrier provision enforces separation between line and load conductors. Together with a heavy‑duty fusible switch architecture, this ensures safer, auditable operation in industrial facilities, warehouses, and processing plants. The rugged construction also supports long service life under demanding conditions, lowering lifecycle costs and improving return on investment. Installation efficiency and compatibility: Fusible without neutral and a three‑wire configuration simplify wiring diagrams for panel builders and electricians. The kit is compatible with large feeder conductors and aligns with standard motor-control circuits, enabling faster installations and easier future expansion. In practice, this means reduced commissioning time, easier spare parts planning, and a smoother path to compliance when upgrading legacy safety switches.
