Eaton REN-110 fuse - Class H
Part Number: REN-110
Quick Summary
REN-110 fuse from Eaton is a time lag protective device for industrial and commercial electrical systems. This solution helps prevent nuisance trips by recognizing brief surges as non faults, reducing unnecessary outages. Note that the data provided does not specify SIL, CE, or IP ratings for this model, so verify with Eaton’s official documentation or datasheets before strict certification commitments. The REN-110 belongs to the Bussmann series protection lineup, offering Class H fusing with non-indicating status for straightforward, cost-effective installation. For procurement and maintenance, its standard packaging and 10-unit quantity streamline stocking, while its compatibility with standard Bussmann-series components supports scalable protection across multiple panels and facilities. This translates to improved reliability and lower total cost of ownership in industrial environments.

Eaton Specification Sheet - REN-110
Feature: Time-lag, non current-limiting design. Business Impact: Enables equipment startups and transient inrush events to pass without unnecessary fuse activation, reducing downtime and maintenance costs. Application: Ideal for motors, transformers, and lighting circuits in industrial and commercial structures where short surges are expected. Feature: 110 A amperage rating. Business Impact: Provides appropriate protection for medium-to-high current feeders, helping prevent conductor damage while preserving system availability. Application: Distribution panels and feeders in process lines and facility power circuits. Feature: Class H fuse element. Business Impact: Delivers reliable, coordinated protection with standard Bussmann-series devices, improving selectivity and fault clearance performance. Application: Electrical protection schemes in commercial buildings and light industrial plants. Feature: Packaging type Standard; Quantity 10. Business Impact: Simplifies procurement logistics and reduces freight costs with consistent packaging across orders. Application: Stocking for maintenance inventories and panel replacements. Feature: Fuse indicator Non-indicating. Business Impact: Requires external status verification, which can lower nuisance tripping indicators in the field while encouraging regular metering checks. Application: Panels where visual indicators are managed by system monitoring rather than fuse body indicators. Feature: Special features – Super lag, time lag, non current-limiting. Business Impact: Combines fast response to true faults with tolerance for momentary surges, lowering total cost of ownership. Application: Industrial control panels, motor starters, and distribution networks requiring robust surge management.

FAQs
The REN-110 is built as a standard Bussmann-series fuse with a Class H element and non-indicating status. It ships in standard packaging with ten units per order, which supports streamline stocking and easier panel replacements. When installing, ensure compatibility with Bussmann-series protective devices in your electrical protection scheme and verify that the 110 A rating matches the feeder or circuit being protected. Always consult the Eaton specification sheet for mounting, clearance, and derating guidance to avoid nuisance trips or improper protection.
Time-lag protection allows brief surge currents during motor start-up to pass without tripping, reducing unnecessary outages. This behavior improves equipment availability and reduces maintenance cycles by preventing short-duration faults from triggering the fuse. In practice, use REN-110 for motors and drive circuits where inrush is expected but sustained faults must be interrupted promptly to protect conductors and equipment.
Yes, the time-lag characteristic accommodates brief surges typical of motor starts and equipment inrush. However, REN-110 is non current-limiting, so it does not automatically constrain fault current magnitudes. For applications requiring rapid current limitation, evaluate alternative fuse types or complementary protection schemes to balance inrush tolerance with fault mitigation.
Procurement details include standard packaging and a quantity of 10 units per order. The fuse has a 110 A rating and comes in a non-indicating form within the Class H family. The provided data lists a UPC of 051712101103 for ordering and inventory matching. The item is part of the Eaton Bussmann series, enabling streamlined stocking and compatibility with other Bussmann-series protective devices.
Official documentation is available through Eaton’s resources: the REN-110 specification sheet, the full Bussmann-series catalog, and the Bussmann Fuseology multimedia video. You can also find a direct specification sheet at Eaton’s site, which provides detailed electrical ratings, installation guidelines, and compatibility notes to support compliant design and procurement decisions.
