FAQs
The TCF17-1/2 is designed for chassis mounting on a standard 35 mm DIN rail and uses blade-end connections for quick, vibration-resistant installation. Its compact dimensions (1.88 in x 0.75 in x 1 in) fit tight panel spaces, reducing enclosure depth. Ensure adequate clearance for heat dissipation and confirm alignment with adjacent devices to prevent contact and interference.
The fuse provides a 17.5 A rating with a voltage rating of 600 Vac / 300 Vdc. Its interrupt ratings are 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, enabling safe interruption of high-energy faults. The 10-second response time at 500% is typical, balancing protection with tolerance to inrush currents in industrial machinery.
Yes. The dual-element, time-delay Class CF design is specifically suited for motor-start and inrush-prone loads, offering selective protection and arc-quenching characteristics. Its UL Listed and CE Marked status supports compliance in multinational facilities, while the finger-safe construction and indicator help minimize maintenance time and misoperation during commissioning or servicing.
The fuse is UL Listed, CSA Certified, and CE Marked, covering safety, performance, and international acceptance. UL and CSA confirm essential safety and reliability for electrical protection devices, while CE Marking demonstrates conformity with European directives. These certifications streamline procurement for global projects and simplify regulatory filings in many industries.
With-indicator status reduces field checks and troubleshooting time, accelerating maintenance workflows. Compatibility with TCFH30N and CCP2-3-30CF families enables straightforward retrofits and scalable protection schemes across growing lineups, lowering total cost of ownership as systems expand and minimizing unscheduled downtime through faster fault identification.
