Feature: Steel enclosure provides rugged protection for terminations in harsh environments. Business Impact: It reduces field damage, simplifies maintenance, and extends enclosure life, lowering total cost of ownership. Application: Ideal for machine control panels and process equipment in manufacturing environments where vibrations, impact, or humidity are common; it pairs well with the Eaton Crouse-Hinds steel switch boxes ecosystem. Feature: 14 cubic inch capacity with a 3 inch depth and 2 inch width ensures ample wiring space in a compact footprint. Business Impact: Improves wire organization, decreases the need for additional boxes, and speeds up panel assembly. Application: Fits tight cabinet spaces in conveyor, packaging, or robotics panels, enabling neater terminations and easier future rework. Feature: Gangable design allows cascading multiple boxes for larger enclosures without swapping hardware. Business Impact: Reduces upfront inventory and future expansion costs, cut down installation time by minimizing separate mounting schemes. Application: Widely used in modular control cabinets and multi-box installations in assembly lines. Feature: Conduit knockouts and routing options—End 3/4 in, Side 3/4 in, Bottom 1/2 in—plus conduit (no clamps). Business Impact: Simplifies wiring runs and reduces hardware fees, while enabling compliant conduit layout according to NEC/CEC. Application: Suitable for ordinary locations requiring organized, code-compliant terminations. Feature: NEC/CEC compliance and UL Canada certifications provide regulatory assurance. Business Impact: Accelerates approvals, improves vendor confidence, and minimizes risk during audits.

FAQs
The TP674 provides End Knockouts of 3/4 in, Side Knockouts of 3/4 in, and a Bottom Knockout of 1/2 in, with conduit routing described as Conduit (no clamps). This supports standard field wiring while allowing clamp installation as needed. The combination enables straightforward routing for typical control panels and reduces the need for additional reducers or adapters, speeding up fit-and-fire installations.
TP674 offers a product length/depth of 3 in, a height of 2.75 in, and a width of 2 in, with a capacity of 14 cubic inches and a weight around 0.58 lb. The gangable steel enclosure is designed to fit into standard control cabinet footprints while providing sufficient space for wiring terminations and simple wiring layouts.
Yes, the TP674 is specified for Ordinary/Non-Hazardous Locations and is manufactured under NEC/CEC standards. Additionally, UL Canadian certifications are available for the steel switch box, providing cross-border regulatory confidence for facilities operating under Canadian and US codes.
The gangable design allows multiple TP674 boxes to be joined to create larger enclosures without swapping to higher-capacity units. This reduces initial inventory, simplifies future expansion, and shortens installation time by preserving a consistent mounting pattern and wiring interface across a multi-box configuration.
The TP674 delivers cost savings through reduced cabinet footprint, faster installation due to standardized knockouts and conduit routing, and longer service life from a robust steel enclosure. When combined with NEC/CEC compliance and UL Canada certifications, it lowers risk during audits and minimizes downtime associated with enclosure failures or non-compliant terminations.
