Ceramic Cartridge Fuse – 5 × 20 mm, Slow-Blow, High Breaking Capacity for Circuit Protection

This ceramic 5 × 20 mm slow‑blow fuse is designed to protect electronic and electrical circuits sensitive to short power surges—such as transformer inrush or motor startup currents. The ceramic tube withstands higher fault energy than glass fuses, and its “T” designation indicates a time-delay characteristic that resists blowing on short-duration overcurrent pulses but clears sustained overloads. Gold/nickel‑plated end caps complete the durable, lead‑free structure compliant with UL, CE, and RoHS standards. The fuse typically supports breaking capacities of ~1,500 A at 250 VAC

Key Features:

• Time-delay (slow-blow) fuse handles short-term inrush currents without nuisance tripping
• 5 × 20 mm industry-standard size for global compatibility
• Ceramic body with high arc suppression for improved durability
• High breaking capacity protects equipment from overcurrent damage
• Designed for both AC and DC circuit applications
• Ideal for power supplies, motors, transformers, and electronic appliances
