FAQs
The TCF70RN uses a blade-end connection and is designed for 35 mm DIN rail mounting in chassis panels. This compact form factor fits standard electrical cabinets without special adapters, and the finger-safe housing reduces risk during maintenance. Replacement is straightforward within the Bussmann CF family, minimizing spare part variety in stock.
The fuse is rated for 70 A with a voltage rating of 600 Vac / 300 Vdc. Its interrupt ratings are 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, ensuring safe fault clearance in high-energy circuits. The device also offers a time-delay response suitable for motor-start surges and transient overloads, aiding selective protection.
Yes. The TCF70RN is specifically designed for 35 mm DIN rail mounting and blade-end connections, making it ideal for control panels, machine cabinets, and OEM enclosures. Its compact dimensions (3.01 in L × 2.125 in H × 1 in W) help save cabinet space while maintaining robust protection for both AC and DC sections.
TCF70RN carries UL Listed and CSA Certified marks, with CE marking and RoHS compliance. These certifications support global regulatory requirements and environmental standards, simplifying cross-border procurement and helping meet internal safety and sustainability goals within quality management systems.
Its time-delay, dual-element design reduces nuisance trips during motor startups, while its high interrupt ratings ensure reliable fault clearance. The DIN-rail mounting and blade-end connection streamline installation and replacements, lowering labor costs and panel downtime. Combined with RoHS/CE/UL/CSA compliance, it supports predictable maintenance cycles and longer mean time between failures.
