Cooper Bussmann ABC-1-R Cartridge Fast-acting Fuse 1A

Product Description

The COOPER BUSSMANN ABC-1-R is a ceramic, cartridge-style, fast-acting mini fuse rated at 1 amp. It measures 1.25 inches in overall length and 0.25 inches in diameter, fitting standard cartridge fuse holders designed for the AGC/ABC fuse format. This fuse provides overcurrent protection in low-current control circuits and is commonly installed by electricians and electronics technicians in HVAC control panels, industrial equipment, and instrumentation. The interrupting rating reaches 10,000 amps at 125 volts and 35 amps at 250 volts, making it suited for low-voltage branch circuit protection where fast response to fault conditions is required.

This fuse is used in residential and light commercial applications where compact overcurrent protection is needed in control circuits, panel boards, and equipment enclosures. It is a common replacement fuse in HVAC control boards, test equipment, and small appliance panels. The fast-acting design responds immediately to overload conditions without the intentional delay characteristic of time-delay fuses, which makes it appropriate for circuits without high inrush current demands.

Key Features

• Fast-acting fuse response — no intentional time delay, protects sensitive circuits from sustained overloads
• 10,000 amp interrupting rating at 125 volts for reliable fault clearing
• 35 amp interrupting rating at 250 volts
• Ceramic body construction for thermal durability and arc containment
• Compact mini cartridge form factor: 1.25 inches OAL, 0.25 inches diameter
• Listed and certified to UL 248-14, CSA 1422-30, and MIL-STD-202 Method 204 and 213

Compatibility

Designed as an OEM-style replacement cartridge fuse for standard ABC and AGC mini fuse holders rated for 1/4-inch diameter cartridge fuses in 125-volt or 250-volt control circuit applications.

Installation Notes

Installation should be performed by a qualified electrician or technician in accordance with NEC guidelines for overcurrent protection devices. Always de-energize and lock out the circuit before removing or replacing a fuse. Verify that the replacement fuse amperage and voltage rating match the circuit requirements before installation. Do not substitute a higher-amperage fuse or use a fuse with a lower interrupting rating than the circuit demands.
