ABB 7TBA050290R0140 Overhead Kit - 400 A Type 3R
Part Number: 7TBA050290R0140
Quick Summary
7TBA050290R0140 is an overhead entry conversion kit used for 2x350 kcmil line-side terminations. Engineers often face unreliable outdoor connections at high currents in meter-socket installations. Key ratings include a weatherproof Type 3R enclosure, a robust 400 A current rating, and a 120/240 V single-phase capability. This kit supports overhead installations with a compact 1 EA package and clear ordering data for procurement. By standardizing the connection approach, maintenance downtime is reduced and field wiring becomes repeatable across assets. The data sheet JS350 provides the technical validation and aligns with field installation best practices for power distribution networks. Designed for Canadian-origin assembly with durable components, it ensures reliability under weather exposure and simplifies ordering.

Feature: Overhead entry compatibility for 2x350 kcmil tunnel connectors used in line-side terminations. Business Impact: Standardizes high-current connections, reduces field rework, and improves installation consistency across crews. Application: Suitable for overhead meter socket installations and service entrances in industrial power-distribution networks where reliability and repeatability are critical. The kit is designed to minimize terminal crowding and simplify torque practice in busy field conditions. Feature: 400 A current rating supports demanding feeders without oversizing hardware. Business Impact: Enables fewer components, lowers total installed cost, reduces potential contact resistance at peak loads, and improves heat management in ratings-critical terminations. Application: Ideal for large motors and high-demand load centers in manufacturing facilities, where robust terminations translate into higher uptime and longer service intervals. Feature: 120/240 V single-phase operation simplifies integration with standard service drops. Business Impact: Reduces configuration complexity, accelerates commissioning, and lowers training requirements for field staff. Application: Suitable for meter-socket contexts in commercial and light-industrial settings, where standard voltages minimize risk during upgrades and retrofits. Feature: Weatherproof Type 3R enclosure provides outdoor reliability and protection from environmental exposure. Business Impact: Extends service life, reduces weather-related failures, and lowers maintenance costs. Application: Outdoor overhead installations at substations, campuses, or remote facilities with variable climates. Feature: Compact 1 EA packaging with UPC 624871005157 and package-level data including 25.4 mm dimensions. Business Impact: Streamlines procurement, improves inventory accuracy, and reduces mis-orders in the supply chain. Application: Per-socket ordering simplifies field logistics and aligns with standard warehouse workflows.

FAQs
The 7TBA050290R0140 is designed specifically as an overhead entry conversion kit for 2x350 kcmil line-side terminations and is compatible with JS4-style meter socket configurations. It comes as 1 kit per socket (1 EA) and uses standard 624871005157 UPC data to streamline ordering and lifecycle management alongside Microlectric and ABB components. For retrofit projects, verify socket geometry and conductor size before field installation.
Installation follows standard field practices for high-current overhead terminations. Start with de-energizing the circuit, prepare the 2x350 kcmil conductors, and follow the JS350 data sheet guidance for connection methods. Attach the kit per socket, ensure a clean, weather-protected interface, and perform final torque checks per facility procedures. Always refer to the JS350 data sheet for installation specifics.
Yes. The kit uses a weatherproof Type 3R enclosure designed for outdoor installations, providing protection against rain, dust, and temperature variations. This rating supports reliable operation in external service entrances and meter-socket applications, reducing maintenance frequency and enhancing uptime in outdoor industrial settings.
Key benefits include standardized high-current connections that reduce field rework, lower component counts, and faster commissioning due to simplified assembly. The 400 A rating supports heavy feeders, while the compact packaging and clear UPC data improve procurement accuracy and inventory control, contributing to reduced downtime and a favorable return on investment over asset lifecycles.
Support documents include the data sheet JS350, which validates technical specs and installation guidance, and the UPC 624871005157 for procurement accuracy. The product is manufactured under ABB with Microlectric labeling, and the model number 7TBA050290R0140 is the official SKU for ordering and cataloging in North American power-distribution projects.
