Eaton UHA Cable Limiter - 100 kAIC
Part Number: UHA
Quick Summary
The Eaton UHA cable limiter protects feeder circuits by safely interrupting high fault currents in panel and switchgear applications. Engineers struggle with downtime from arcing, nuisance trips, and the resulting maintenance costs. This device is RoHS compliant and rated for 250 V with a 100 kAIC interrupt rating, aligning with common industrial protection standards. In practice, it provides reliable, high-current protection for low-voltage feeders, reducing fuse replacements and unplanned outages. The UHA's center bolt end with offset bolted end design simplifies installation and ensures robust, field-friendly connections in compact equipment footprints. By integrating this limiter, maintenance teams gain predictable performance and easier procurement for standard Eaton Bussmann series components.

FAQs
Installers should observe the center bolt end x offset bolted end connection as the primary mounting interface. The unit supports copper #2/0 AWG and aluminum #4/0 AWG conductors, requiring proper conductor terminations and compatible fittings. Refer to Eaton datasheets for torque guidelines and enclosure clearance. Ensure RoHS-compliant materials are used and verify the 0.97 in depth, 4.3 in height, and 1.1 in width fit within the intended panel or switchgear footprint.
The UHA features a 100 kAIC interrupt rating and a 250 V voltage rating, suitable for low-voltage feeder protection. It accepts Cu #2/0 AWG and Al #4/0 AWG conductors, and it is RoHS compliant. These specs support reliable fault-current interruption in standard industrial power distribution equipment and align with Bussmann series compatibility.
Yes. The UHA is designed for feeder protection in panel boards, switchgear, and distribution assemblies. Its center bolt end and offset bolted end configuration facilitate robust installations, and its compatibility with Cu #2/0 AWG and Al #4/0 AWG conductors makes it easy to upgrade existing feeders without complex rewiring. RoHS compliance adds environmental relevance for modern facilities.
The UHA is RoHS compliant, supporting regulatory environmental requirements across many markets. While the data specifies RoHS, users should consult Eaton’s datasheet for any additional regional safety certifications (such as CE or UL) relevant to their site. RoHS compliance helps ensure restricted substances are managed in accordance with industry standards.
The UHA delivers high-current protection with a 100 kAIC rating, reducing downtime and maintenance costs from fault events. Its compatibility with common conductor sizes and center bolt/offset end connections speeds installation, while RoHS compliance supports regulatory conformity. Integrated with Eaton Bussmann series components, it simplifies procurement and ensures scalable, reliable feeder protection.
