Cooper Bussmann AGC-1-1/4-R Cartridge Fast-acting Fuse

Product Description

The COOPER BUSSMANN AGC-1-1/4-R is a glass-body, cartridge-style fast-acting fuse rated at 1.25 amps. It measures 1.25 inches in overall length and 0.25 inches in diameter, conforming to the standard AGC miniature fuse form factor. The fast-acting element responds immediately to overload conditions without intentional time delay, making it appropriate for protecting sensitive electronic circuits, instruments, and control equipment. Interrupting capacity is rated at 10,000 amps at 125 volts and 100 amps at 250 volts. Licensed electricians and electronics technicians are the typical installers for this class of fuse in panel, chassis, and inline fuse holder applications.

This fuse is suited for residential and light commercial control circuits, instrumentation panels, HVAC low-voltage control boards, and general electronics where a standard 1/4-inch by 1-1/4-inch cartridge fuse position is present. Its glass body allows visual inspection of the element for quick field diagnosis without a meter. The RoHS-compliant construction makes it appropriate for use in environmentally regulated equipment assemblies.

Installation Notes

Installation and replacement should be performed by a qualified electrician or electronics technician. Always de-energize and lock out the circuit before replacing a fuse. Verify the replacement fuse amperage and voltage rating match the circuit requirements exactly before inserting into the fuse holder. Never substitute a higher-amperage fuse to bypass a recurring overcurrent condition without first diagnosing the root cause.
