Time-delay, dual-element construction delivers coordinated protection for circuits with startup surges. This means fewer nuisance trips and longer equipment life, translating to lower maintenance costs and improved plant uptime. Use in control panels and motor-driven loads where inrush is common. Certification and compliance features, including UL Listed and RoHS, ensure safe integration into regulated assemblies and easier supplier qualification. This supports faster procurement cycles and traceability in regulated industries. The blade-end connection simplifies retrofit projects and minimizes field wiring errors, enabling quicker maintenance and safer installations. Finger-safe design reduces exposure during handling, improving technician safety and reducing risk of incidental contact. The compact form factor (3.63 in L Ă— 2.95 in H Ă— 1.32 in W) fits standard fuse blocks and panel spaces, aiding in efficient panel design and reduced enclosure footprint. The non-indicating, dual-element cube fuse provides reliable operation without nuisance indicator wear, lowering maintenance overhead. Used with compatible Bussmann series products like TCFH200N and CCP2-3-200CF, this fuse offers scalable protection for enterprise-level control schemes and modular power distributions. In real-world deployments, the TCF125RN helps you meet uptime targets while controlling replacement costs and inventory with a single, standards-aligned component.

FAQs
The TCF125RN uses a blade-end connection and is designed for standard Bussmann cube fuse holders and compatible CS/CF panel layouts. Its 3.63 x 2.95 x 1.32 inch form factor fits typical control panels and compact enclosures, simplifying retrofits and new installations without rearranging existing wiring.
TCF125RN is rated for 125 A amperage and 600 V voltage, with an interrupt rating of 200 kAIC at 600 VAC and 100 kAIC at 300 Vdc. These ratings support protection of medium-power circuits against short circuits and overloads while enabling coordination with other protective devices.
Yes. As a Class CF time-delay fuse with dual-element protection, it tolerates motor inrush and startup surges while providing selective coordination with downstream devices. It’s well-suited for motor starters, drives, and other loads with transient currents, helping prevent unnecessary outages and improving uptime.
The TCF125RN is UL Listed and RoHS Compliant. These certifications support safe integration into regulated electrical builds, ease procurement with recognized sustainability commitments, and offer traceability for quality assurance and compliance reporting in industrial environments.
The time-delay, dual-element design reduces nuisance trips and extends equipment life, lowering maintenance frequency. Its non-indicating feature minimizes wear on indicators, while RoHS and UL listings streamline procurement and compliance. Overall, this translates to lower lifecycle costs, fewer outages, and faster panel replacements for OEMs and maintenance teams.
