Eaton abc-1-r Fast-acting Ceramic Fuse 1A 250 Vac

Product Description

The EATON abc-1-r is a fast-acting ceramic fuse from the Eaton Bussmann series, rated at 1 amp and 250 Vac (125 Vdc). It is designed to protect sensitive electronic circuits from overcurrent conditions by opening quickly when fault current is detected. The fuse features a ceramic tube body with nickel-plated brass ferrule endcaps and carries a non-indicating design, meaning there is no visual blown indicator. Sold in a quantity of 5 per pack, this fuse is well suited for licensed electricians and electronics technicians working on low-current circuit protection applications.

This fuse is intended for use in electronic circuit protection across a range of light commercial and industrial applications. Its fast-acting response makes it appropriate for protecting components that cannot tolerate sustained overcurrent without damage. Typical install scenarios include control boards, instrumentation panels, and electronic equipment where a small-diameter ferrule-end fuse is required. The 250 Vac voltage rating also accommodates 32 Vac self-certified applications.

Key Features

• Fast-acting response: opens in under 120 seconds at 200% of rated current
• Ceramic tube construction with nickel-plated brass endcaps for durability
• Ferrule end x ferrule end connection for secure panel or holder mounting
• Interrupt rating of 35 AIC at 250 Vac and 10 kAIC at 125 Vac/dc
• CE Marked and RoHS Compliant
• Non-indicating design — no external blown indicator

Compatibility

Designed as an OEM-style replacement for fast-acting ferrule fuses used in electronic circuit protection applications rated at 1 amp and 250 Vac.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse amperage, voltage, and interrupt rating match the requirements of the protected circuit before installation. Consult applicable NEC guidelines for overcurrent protection device selection and replacement procedures.
