FAQs
The TCF25RN uses blade-end connections and is designed for 35 mm DIN rail mounting in chassis panels. Its compact 1.88 in length and 0.75 in width fit tight control panel spaces while maintaining easy replacement. The finger-safe housing reduces handling risk during installation and maintenance, supporting safe, field-ready protection near motor drives and power electronics.
The fuse is rated for 25 A with a voltage rating of 600 Vac and 300 Vdc. It provides an interruption rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, ensuring strong fault protection for high-energy circuits. The 5–60 Hz operating range supports typical industrial power environments.
Yes. The dual-element time-delay design of the Class CF fuse accommodates motor inrush and startup surges without nuisance tripping while still delivering fast fault interruption. This makes it ideal for motor drives, controls, and power conversion equipment where overload and surge events are common.
The TCF25RN is UL Listed and CSA Certified, with CE Marking and RoHS compliance. These certifications support global deployment, regulatory approvals, and environmental considerations, reducing compliance risk in multinational manufacturing environments.
By combining reliable time-delay protection with high interrupt ratings and compact DIN-rail installation, the TCF25RN minimizes downtime from nuisance trips and simplifies panel upgrades. Its durable construction and standard compatibility with other Bussmann CF products reduce spare part variety and inventory costs, delivering measurable ROI for maintenance-intensive applications.
