Abb TR250R Tri-Onic® SmartSpot® TR Series Class RK5 Time-Delay Fuse

Product Description

The ABB TR250R Tri-Onic TR-R current-limiting time-delay fuse is engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders, and branch-circuits. The time-delay characteristics safely handle harmless starting currents and inrush currents associated with today's motors and transformers.

• Time-delay for motor start-ups and transformer inrush currents without nuisance opening
• Current-limiting for low peak let-thru current
• Rejection-style design prevents replacement errors (when used with recommended fuse block)

Product Highlights

This Class RK5 fuse provides time-delay and current limiting protection. Suitable for use in circuits up to 250 VAC with an interrupt rating of 200kA.
