BUSSMANN TR2/6125FF3-R Surface Mount Fuse, Fast Blow, 3 A, 72 VAC

Bussmann TR2/6125FF3-R surface mount fuse safeguards against overcurrent and short-circuit conditions. Its compact size and surface mount design make it suitable for modern electronics where space is limited. Commonly used in consumer electronics, automotive electronics and industrial equipment, this Bussmann fuse ensures the protection of sensitive components by interrupting the circuit in case of excessive current flow.

Working Mechanism:

• Bussmann TR2/6125FF3-R SMD fuse operates based on the principle of overcurrent protection.
• When the current flowing through the circuit exceeds the rated capacity of the fuse, the conductive element heats up due to increased resistance.
• As the temperature rises, a critical point is reached where the element melts or blows, creating an open circuit and interrupting the current flow. This prevents excessive current from damaging components or causing hazards.

Frequently Asked Questions:

Q. What is the significance of interrupt rating in fuse?

A. The interrupting rating denotes the maximum fault current the fuse can safely interrupt without causing harm. It is mandatory to select a fuse with an interrupting rating that matches or exceeds the potential fault current in your circuit.

Q. What is the mounting orientation of this SMD fuse?

A. This Bussmann SMD fuse offers surface mounting, making it suitable for installation on flat surfaces.

Q. What is the difference between bolt down and surface mount fuse?

A. The surface mount's top has a rounded edge and is mounted by a soldering rework station, while the bolt-down fuse has a cavity in the fuse's blade for mounting.
