Feature: The TP830 delivers 22 cubic inches of capacity in a 4-inch square, 2-1/8 inch deep steel box. Business impact: This generous interior allows more room for splices, devices, and connectors, reducing overfill risk and simplifying wiring harnesses in compact control panels. Application: Use in automation cabinets where dense wiring and clean routing are critical for reliability and serviceability. Feature: It provides (8) 1/2 in and (4) 3/4 in knockouts on the sides and bottom, plus conduit with no clamps. Business impact: Flexibility to route cables from multiple directions without additional fittings lowers install time and procurement costs. Application: Perfect for machine enclosures that receive sensors, relays, and motor starters from various feed-through points. Feature: Air plenum is integrated to promote airflow and cooling inside the enclosure. Business impact: Improved thermal performance can extend device life, stabilize performance, and reduce risk of thermal shutdown in high-density control panels. Application: Recommended where powered drives and controllers share cabinet real estate and heat buildup is a concern. Feature: Drawn steel construction and lightweight design with an approximate weight of 0.66 lb. Business impact: Enhances handling during installation and simplifies mounting while delivering robust mechanical protection against impacts and vibration common in industrial settings. Application: Suitable for overhead or wall-mounted installations in manufacturing lines and warehouse automation. Feature: NEC/CEC standards compliance and Ordinary/Non-Hazardous location classification. Business impact: Regulatory alignment reduces approval cycles, speeds project sign-offs, and ensures safe operation in non-hazardous environments. Application: fits standard Eaton/Crouse-Hinds square box ecosystems in commercial facilities and rugged factory floors. Feature: Overall compatibility with the 4-inch square box family and cable management accessories.

FAQs
The TP830 is a 4-inch square steel box with eight 1/2 in and four 3/4 in knockouts on the sides and bottom, conduit with no clamps, depth of 2-1/8 in, and weight around 0.66 lb. Plan knockout layout to route conductors efficiently, use the air plenum for cooling, and mount to standard mounting patterns in control panels.
Yes. The TP830 carries NEC/CEC standards and is rated for Ordinary/Non-Hazardous locations. The heavy-duty steel construction combined with an air plenum supports reliable operation in non-hazardous environments while maintaining a compact footprint for small control cabinets.
TP830 uses conduit with no clamps and drawn steel construction, plus standardized 4-inch box sizing with multiple knockouts. This enables seamless integration with other Eaton/Crouse-Hinds steel square boxes, simplifies splicing and wiring, and reduces on-site modification and part count.
Ideal for control panels, machine enclosures, and junction boxes in non-hazardous zones. The 22 cu in capacity, multiple knockouts, and air plenum support efficient wiring, cooling, and reliable device mounting in automation cabinets and field installations.
Durable drawn steel construction resists impact and corrosion, lowering replacement costs. The air plenum improves heat management, reducing thermal stress on components, while the clamp-free conduit option saves installation time and labor costs, contributing to a lower total cost of ownership over the equipment life cycle.
