FAQs
Yes. The TCF30 uses a blade-end connection and is designed to be drop-in compatible with Bussmann series cube fuses and standard protection panels. This simplifies retrofits and new installations, reducing wiring time and the risk of mis-matched components in control cabinets.
The TCF30 is rated at 30 A with a voltage rating of 600 Vac and 300 Vdc, and an interrupt rating of up to 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc. These specs support motor drives, power distribution feeders, and inrush-prone loads while maintaining fast fault clearance and system protection.
Time-delay Class CF fuses like the TCF30 are ideal for motors, conveyors, and automation panels where inrush currents are common. They provide long-term protection without nuisance trips during startup, enabling safer start-ups and reduced downtime in manufacturing environments.
The TCF30 carries UL Listed and CSA Certified marks, along with RoHS compliance. These certifications verify electrical safety, cross-border acceptance, and environmental responsibility, which are critical for OEMs selling equipment globally and for regulatory audits.
The indicating fuse provides immediate status visibility, reducing inspection time and enabling quicker fault isolation. This lowers mean time to repair (MTTR), minimizes unplanned downtime, and improves overall equipment efficiency, contributing to a lower total cost of ownership over the product lifecycle.
