Micro Fuse T2A 250V – 2A Slow-Blow Radial Leaded Fuse

The Micro Fuse T2A 250V is a compact, time-delay (slow-blow) electrical fuse designed to protect electronic circuits and equipment against excessive current and short-circuit conditions.

Rated at 2A and 250V AC, this radial leaded fuse is designed to tolerate brief current surges, such as startup or inrush currents, while providing overcurrent protection.

Its compact cylindrical body and two radial leads make it suitable for through-hole PCB mounting in power supplies, electronic control boards, appliances, and other electrical equipment.

Key Features

• 2A Rated Current: Designed for circuits requiring a 2-ampere fuse rating.
• 250V AC Voltage Rating: Suitable for applications within the specified voltage rating.
• Slow-Blow Protection: Time-delay characteristic tolerates brief startup current surges.
• Radial Leaded Design: Two leads for through-hole PCB installation.
• Compact Construction: Suitable for electronic circuits with limited PCB space.
• Overcurrent Protection: Interrupts excessive current under specified operating conditions.
• Single-Use Protection: Must be replaced after the fuse opens.
• PCB Compatible: Suitable for electronic equipment and power supply circuit boards.

Technical Specifications

Note: The listed 100A breaking capacity is taken from the supplied product information and should be verified against the manufacturer's datasheet before use in mains-powered equipment.

Pin Configuration

The fuse has two radial leads.

The fuse is non-polarized and can be installed in either direction.

Basic Connection Example

The fuse is installed in series with the circuit or equipment being protected.

Typical Connection:

Power Source → T2A Fuse → Electrical Load

When the current exceeds the fuse's time-current limits, the internal fuse element opens and interrupts the circuit.

Important: The fuse must be selected according to the equipment's operating current, startup current, voltage, available fault current, and required protection characteristics.

Applications

• Electronic power supplies
• PCB overcurrent protection
• AC-powered electronic equipment
• Industrial control boards
• Electronic appliances
• Power input protection circuits
• Electrical control systems
• Equipment repair and maintenance
• Replacement fuse applications
• Electronic circuit assembly

Important Notes

• The T2A marking indicates a 2A time-delay fuse.
• A slow-blow fuse tolerates short-duration current surges better than a fast-acting fuse of the same rating.
• The 2A rating does not mean the fuse will open immediately when current exceeds 2A.
• The fuse is a single-use protective component and must be replaced after it blows.
• Do not bypass a blown fuse using wire or other conductive materials.
• Replace the fuse only with one having the correct current, voltage, time-delay, and breaking-capacity specifications.
• The voltage rating must not be exceeded.
• The fuse's breaking capacity must be greater than the prospective short-circuit current at its installation point.
• The listed 100A breaking capacity requires manufacturer verification.
• A 250V AC rating does not automatically establish suitability for 250V DC applications.
• Do not assume the fuse is certified to IEC, UL, or other standards without supporting documentation.
• Disconnect the power supply before installing or replacing the fuse.
• For mains-powered equipment, installation and replacement should be performed by a qualified person.
• Verify the physical dimensions and lead spacing before replacing an existing PCB fuse.
• This fuse provides overcurrent protection and does not replace proper grounding, insulation, or other electrical safety measures.
