Bussmann TCF35RN Time-Delay Ceramic Fuse

(35 Amp, 250V AC/DC, Rejection Base)

Reliable Circuit Protection

The TCF35RN tubular fuse from Eaton’s Bussmann Series delivers precision overcurrent protection for industrial and commercial applications. Designed for demanding environments, its time-delay characteristic prevents nuisance tripping during motor startups or inrush currents while providing robust short-circuit interruption.

Key Features

• Current Rating: 35 Amps
• Voltage Rating: 250V AC/DC
• Time-Delay Performance: Withstands 500% overload for 10 seconds (minimizes false trips)
• High Interrupt Capacity: 300kA @ 250V AC (protects against catastrophic faults)
• Ceramic Construction: Flame-retardant tube with quartz sand filler for arc suppression
• Rejection Base (R): Patented notch prevents installation in incompatible fuseholders
• UL/CSA Certified: Complies with UL 248-14 and CSA standards

Applications

• Motor control centers
• HVAC systems
• Industrial machinery
• Power distribution panels
• Transformer protection

Safety & Compatibility

The “RN” suffix ensures this fuse only fits holders rated ≤35A, preventing accidental over-fusing. Silver-plated brass end caps maintain low resistance and corrosion resistance.

Dimensions: 1-1/2″ (38.1mm) length × 13/32″ (10.3mm) diameter
Operating Temp: -50°C to +125°C

Trusted protection where uptime matters – engineered for resilience in critical circuits.
