FAQs
To install H1037, thread the bushing into the enclosure or conduit opening until seated, ensure the IMC conduit threads engage cleanly, and torque to manufacturer recommendations. Verify insulation remains intact and the face sits flush against the enclosure to prevent ingress. The 2-1/2" trade size aligns with standard IMC fittings, simplifying stocking and interchangeability.
Key specs include a 150°C temperature rating, insulated construction, and malleable iron material. These features minimize insulation degradation and arcing risk during thermal cycling. The 3.31 in length and 3.31 in width provide a stable mounting footprint for secure, long-lasting connections in control panels and equipment housings.
Yes. The product is categorized for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards, making it suitable for typical industrial facilities and non-hazardous parts of control cabinets where standard conduit fittings are required.
UL certifications for Rigid-IMC throat bushings are documented in the product downloads. Refer to the UL certification pages and Eaton’s specification sheet to confirm compliance for your region. This supports audit readiness and regulatory verification during procurement and installation.
The insulated, threaded design reduces insulation wear and arcing, lowering maintenance frequency and downtime.
