Eaton UHJ-T Cable Limiter - 100 kAIC Rating for 250V
Part Number: UHJ-T
Quick Summary
The Eaton UHJ-T cable limiter provides high-current protection for industrial power distribution networks. Engineers often struggle to balance compact size with safe fault-current interruption in large-diameter feeder runs. No formal certifications are listed for this specific part in the datasheet, but it is rated for 250 V and 100 kAIC. This combination supports reliable service entrances and high-current feeder protection, delivering faster fault clearance and reduced downtime. In practice, you gain compatibility with copper and aluminum conductors, plus a compact footprint for tight panel layouts. The product's non-indicating design reduces panel clutter and simplifies replacement when you don't need status cues. Overall, UHJ-T supports efficient procurement with a focused Eaton Bussmann ecosystem while addressing key high-current safety concerns.

FAQs
Install the UHJ-T with copper conductors up to 350 kcmil or aluminum up to 500 kcmil, ensuring correct alignment between the center bolt end and the offset bolted end. Use standard hardware compatible with Bussmann series components, and secure the limiter within the panel enclosure according to your facility’s wiring practices. After assembly, verify conductor torque and start-up sequencing to confirm proper fault interruption path.
The UHJ-T supports copper conductors up to 350 kcmil and aluminum conductors up to 500 kcmil. It is rated for 250 V and an interrupt rating of 100 kAIC, making it suitable for high-current feeder protection in industrial distributions that use the Bussmann series protection ecosystem.
Yes. With a 100 kAIC interrupt rating and 250 V operation, the UHJ-T is designed for demanding feeder protection in industrial panels. Its compact 4.87 inch length and center bolt end with offset bolted end facilitate installation in tight spaces while maintaining robust current interruption characteristics.
The datasheet notes Not Applicable for Compliances and Warranty, and no specific certifications are listed. For regulatory compliance in your region, verify through local electrical standards and confirm compatibility with your project specifications. The device’s electrical ratings (100 kAIC, 250 V) should be evaluated against your system requirements.
The UHJ-T delivers a clear ROI through enhanced fault protection, reduced downtime, and streamlined maintenance in high-current feeder applications. Its compatibility with copper and aluminum conductors supports flexible design, while its compact footprint can lower panel redesign costs. Aligning with Eaton Bussmann components also simplifies spares management and long-term support.
