FAQs
Install the TCF45RNW into a compatible fuse holder that supports blade-end connections. Ensure the panel bus and holder are rated for 690 Vac and match the 45 A rating. Verify proper alignment of the blade contacts, tighten mounting hardware to spec, and restore power while observing lockout/tagout procedures. The compact 2.13 in length eases retrofits in tight spaces.
The TCF45RNW is a Class CF time-delay fuse designed to tolerate temporary inrush while protecting downstream circuits. Use it in motor control centers, conveyors, and panels with 50/60 Hz loads where startup surges occur but sustained faults must be cleared quickly. Its 50 kAIC interrupt rating ensures robust fault handling in common industrial applications.
Yes, the TCF45RNW is rated for 690 Vac and supports 50/60 Hz operation. It is UL Listed, CSA Certified, and CE Marked RoHS compliant, which helps satisfy global regulatory requirements for safety, environmental impact, and product traceability in electrical protection installations.
Confirm blade-end mounting compatibility, ensure the panel provides a Bussmann-series, Class CF time-delay fuse path, and verify the 45 A rating aligns with circuit load. The TCF45RNW is designed to work with related parts like TCFH60NW and standard Bussmann catalogs, simplifying stocking and cross-referencing in repair and replacement scenarios.
The TCF45RNW reduces downtime by tolerating inrush surges without nuisance trips, lowers maintenance costs with durable PES material, and supports regulatory compliance with UL, CSA, and CE RoHS. Its compact form and blade-end design accelerate installation, shorten commissioning, and improve panel reliability over time.
