FAQs
The TCF45RN uses a chassis 35 mm DIN rail mounting with blade-end connections for simple drop-in installation in standard control panels. It is compatible with Bussmann Series devices such as TCFH60N and CCP2-3-60CF, which streamlines spare parts stocking and ensures consistent protection across the drive and controller environment.
The fuse is rated at 45 A with voltage ratings of 600 Vac and 300 Vdc. It provides an interrupt rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, enabling it to safely interrupt high fault currents in typical industrial power distribution and motor circuits.
Yes. As a Class CF time-delay fuse with dual-element current limiting, it tolerates transient inrush associated with motor start-up, reducing nuisance trips while still delivering fast fault clearance. This makes it well suited for motor control centers, conveyors, pumps, and other motor-driven loads.
The TCF45RN is UL Listed and CSA Certified, CE marked, and RoHS compliant. These certifications support global procurement, regulatory approval, and eco-friendly material compliance for OEMs and end users in diverse markets.
The dual-element, time-delay design minimizes downtime due to nuisance trips, while its robust interrupt ratings protect upstream components. Its DIN-rail compatibility and compatibility with related Bussmann devices streamline stocking and maintenance, reducing spare-part costs and improving overall system reliability in power distribution and control panels.
