FAQs
Install the TCF1RNW with its blade-end connections into compatible fuse holders inside the control panel. Ensure circuitry is de-energized, align the blade contacts securely, and verify proper fit within the standard fuse packaging. With a 1 A rating and 690 VAC capability, confirm the circuit voltage and current match prior to replacement to avoid nuisance trips or equipment damage.
Key specs include Amperage Rating of 1 A, Voltage Rating of 690 VAC, Frequency range of 50–60 Hz, Interrupt Rating of 50 kAIC, and a Class CF time-delay fuse type. It is designed for dual-element operation with blade-end connections and a 1.88 in length, 1.75 in height, and 0.75 in width.
Yes, the TCF1RNW is designed for use with related Bussmann series components and shares the blade-end connection and Class CF time-delay characteristics, enabling coordinated protection in modular panel installations and simple cross-compatibility within the Bussmann/TCF family.
The TCF1RNW carries UL Listed and CSA Certified marks, along with CE marking. These certifications support compliance for global installations and facilitate acceptance in diverse regulatory environments, reducing vendor risk and accelerating procurement approval.
Inrush-tolerant operation minimizes nuisance tripping in motor starts and control circuits, reducing unplanned downtime and maintenance costs. The fuse’s robust 50 kAIC interruption capacity also lowers the likelihood of downstream damage, extending equipment life and improving overall productivity in automation lines.
