2pcs glass fuse 1 amp

🔹 2pcs 5x20mm 1A Fast-Blow Glass Fuse – 250V

This pack contains two 5x20mm glass cartridge fuses rated at 1 ampere with fast-blow characteristics. Designed for reliable overcurrent protection in electronics, power supplies, instruments, and low-power equipment requiring 1A protection.

✅ Specifications:

• Fuse Size: 5mm x 20mm (standard glass cartridge)

• Current Rating: 1 Ampere (1A)

• Fuse Type: Fast-Blow / Fast-Acting

• Voltage Rating: 250V AC

• Body Material: Clear glass tube

• End Caps: Nickel-plated brass

• Interrupting Rating: 100A @ 250V AC (typical)

• Melting Integral (I²t): Low, suitable for fast overcurrent protection

• Marking: “1A” clearly printed on one end cap

• Quantity: 2 Pieces

📦 Applications:
✔️ Power supply input/output protection (1A circuits)
✔️ Multimeters and test equipment protection
✔️ Audio preamps and signal processors
✔️ Low-power appliances and electronics
✔️ Control panels and instrumentation
✔️ DIY electronics projects drawing up to 0.8A continuous
✔️ Replacement fuses for equipment with 1A fast-blow requirement

📦 Common 1A Applications:

• Bench power supplies (low-current models)

• Digital multimeters (DMMs)

• Soldering stations (low-power models)

• Small transformers and adapters

• Timer and relay circuits

• Analog audio equipment

• 3D printer control boards (logic circuits)

⚠️ Important Safety Notes:

• DC applications: Verify the fuse’s DC voltage rating if used in DC circuits (typically lower than AC rating).

• Inrush current: Fast-blow fuses may blow during startup of equipment with high inrush currents (transformers, motors, capacitors). Consider slow-blow fuses for such applications.

• Always replace fuses with the same type and rating as the original.

• Disconnect power before replacing fuses.

• Never bypass or jumper a blown fuse.
