FAQs
The 1HD426 is designed as part of the COMMANDER SAFETY SWITCH V3 family, providing seamless compatibility with Eaton’s safety devices. It uses the catalog number 1HD426 and standard mounting and wiring practices, enabling straightforward upgrades or integration within existing safety schemes. This compatibility reduces engineering effort and minimizes downtime during installations or replacements.
UL Listed certification confirms compliance with recognized safety standards, simplifying inspection and approval processes. installations can rely on proven performance under fault conditions, and the labeling supports traceability for regulatory reviews. In practice, you’ll experience clearer documentation, consistent safety messaging on-site, and fewer delays during audits or safety reviews.
The unit measures 29 inches in length, 17 inches in width, and 9.5 inches in height, with an approximate weight of 30 pounds. It is designed for rugged environments and aligns with common enclosure footprints. For mounting, ensure solid mechanical supports and clearances per the NEC requirements, and plan space for routine maintenance access around the device.
As a heavy-duty fusible switch with a robust construction, the 1HD426 typically offers long service intervals with minimal routine maintenance beyond visual inspections and contact resistance checks. Its durable build reduces spare-part demands, lowers unplanned downtime, and extends the interval between panel maintenance cycles, contributing to lower lifecycle costs for industrial facilities.
A fusible safety switch provides deliberate, discrete disconnection under fault, enabling targeted protection of downstream equipment and operators. This design reduces the risk of arc flash events and allows selective protection coordination. In automation panels, the 1HD426 offers reliable isolation for high-load circuits while supporting clear maintenance procedures and compliance with industrial safety standards.
