Eaton HS1040 Throat Bushing - 150°C Insulated
Part Number: HS1040
Quick Summary
HS1040 throat bushing is an insulated, set-screw termination for rigid/IMC conduit used in industrial electrical installations. Engineers often encounter installation delays and insulation challenges when terminating conduits, especially in non-hazardous environments. This part aligns with NEC/CEC standards and UL Canadian certification, providing reliability in ordinary locations while simplifying compliance. The 4" trade size, 150°C temperature rating, and insulated body support robust performance, reduced maintenance, and safer, longer-lasting terminations. For procurement teams, it pairs well with standard rigid/IMC fittings and minimizes field rework while preserving system integrity.

FAQs
HS1040 is designed for rigid/IMC conduit. Its threadless construction simplifies field installs by allowing a straightforward set-screw termination without the need to cut or chase threads, reducing labor time and risk of thread damage while maintaining a secure, code-compliant connection.
HS1040 is insulated and rated for up to 150°C, which ensures reliable performance in environments with elevated temperatures. The insulation minimizes arcing potential and maintains electrical integrity across standard industrial enclosures, contributing to safer operation and longer component life.
Yes, HS1040 is intended for Ordinary/Non-Hazardous Locations and aligns with NEC/CEC standards. It is supported by Canadian UL certification, which helps satisfy regional compliance requirements and streamlines project approvals in North American facilities.
HS1040 complies with NEC/CEC standards and carries UL Canadian certification, offering regulatory assurance for cross-border projects. This combination supports safe, reliable conduit terminations in non-hazardous areas and broad industry acceptance.
The set-screw, threadless design reduces installation labor and field rework. The insulated malleable iron body provides durable performance with lower replacement frequency. Together, these factors lower maintenance costs, minimize downtime, and improve ROI for mid- to large-scale automation and electrical installations.
