Applications
The TR3-2/10R fuses are ideal for protecting motors, transformers, service entrance equipment, feeders, and branch circuits. Their time-delay characteristics allow them to handle harmless inrush currents associated with motor startups and transformer energization without nuisance opening.
Compliance and Standards
These fuses comply with UL 248-12 and CSA C22.2 No. 248.12 standards, ensuring they meet rigorous safety and performance requirements. They are also RoHS compliant, reflecting a commitment to environmental responsibility.
Additional Information
The rejection-style design of the TR3-2/10R prevents replacement errors when used with recommended fuse blocks. The fiberglass body provides dimensional stability in harsh industrial settings, and the high-grade silica filler ensures fast arc quenching and high current limitation.
