3AG 10-R

Fuses

Fuses are an important part of an electrical system and play a vital role in preventing electrical overloading or short-circuiting. 3AG 10-R is a type of miniature circuit breaker fuse frequently used in low-voltage electrical systems, especially in computer and control circuitry.

3AG 10-R is designed to be used in high frequency, high current circuits. It is typically used in systems that have a load rating up to 18 amps, with voltage ratings between 70 and 600 volts. It is also suitable for use with typical peak current ratings up to 20 amps and with disruptive discharge currents up to 20,000 amps. It has an interrupting rating of 10,000 amps.

The 3AG 10-R fuse is constructed with a base metal element, two sintering walls on the ends, two screw galls in the middle, and a flag indicator to show that the fuse has been blown. The sintering walls serve as temperature-dependent resettable shorting links for conductors between the flags. The partitions between the conductors and the base metal element serve as a protective barrier to reduce electrical arcing.

Due to its small size, the 3AG 10-R is ideal for equipment with limited panel space. It is also lightweight, making it easier to mount than heavier, larger circuit breakers. The fuse is designed to be used in a wide range of equipment, including computers, control circuits, instrumentation and process control, as well as test equipment and robot systems. It is also used in motor control systems and other applications with medium voltage power.

The 3AG 10-R fuse is designed to be an economical choice compared to other circuit protection options. It provides reliable protection when used within its rating limitations and is capable of offering a wide range of interruption ratings.

The working principle of the 3AG 10-R fuse is to limit the amount of current passing through the device. When the fuse is operational, the current flowing through it will be regulated to the values specified by its ratings. When too much current passes through the fuse, the metal element expands due to the heat generated from the high current, and the two sintering walls snap open, breaking the circuit. This is what causes the flag indicator to move, and the fuse is said to be “blown”.

In summary, the 3AG 10-R fuse is a compact, lightweight, economical circuit breaker that is used in a variety of applications. It is designed to regulate and protect electrical systems from excessive current. It works by limiting the amount of current that passes through, and when too much current passes through, the fuse snaps open, breaking the circuit and indicating that it has been blown.
