FAQs
The 12HD266 is designed for straightforward integration within standard industrial control enclosures and aligns with Eaton’s safety switch ecosystem. Its 29 in L, 17 in W, and 9.5 in H footprint supports common mounting patterns, and the unit’s rugged construction ensures reliable operation in busy panels. When replacing older fusible switches, verify mounting clearance and wiring harness compatibility to minimize rework.
The 12HD266 features a compliant barrier that meets NEC 230.62 (C) requirements, helping maintain safe separation between live parts and accessible surfaces. UL Listed certification further reinforces safety and traceability. For installation planning, ensure barrier integrity and proper labeling, and document compliance in your switchgear maintenance records to simplify audits.
Best suited for industrial power distribution and motor control applications, the 12HD266 provides reliable isolation for high-demand lines and critical equipment. It’s ideal in production lines, pump rooms, and hazardous-area feed circuits where safe, quick disconnects support preventive maintenance and emergency shutdown procedures, while meeting stringent protective-device requirements.
Plan for a 29 in L × 17 in W × 9.5 in H enclosure with an approximate 30 lb weight to ensure proper mounting and handling. Check available mounting space, conduit entry arrangements, and wiring access clearance. Use appropriate lifting equipment and verify that panel openings accommodate the unit without structural modification to preserve barrier integrity.
UL Listed safety switches provide proven reliability and straightforward regulatory compliance, reducing downtime and inspection burdens. The 12HD266’s robust design minimizes field failures, lowers maintenance frequency, and simplifies spare-part planning within Eaton ecosystems. Over the equipment lifecycle, this translates to lower total cost of ownership and improved plant safety performance.
