Eaton BAF-2-1/2 Fuse - CE Marked Fast-Acting
Part Number: BAF-2-1/2
Quick Summary
The Eaton BAF-2-1/2 fuse is a fast-acting protection device designed for control circuits in industrial panels. This fuse helps prevent costly damage from overcurrents while keeping panel layouts compact. Engineers often struggle with nuisance trips and limited space in modern equipment, but this part delivers reliable interruption without adding bulk. CE marking confirms European safety compliance, while its 2.5 A rating and 250 V operation support common automation and instrumentation needs. By combining a ferrule-end connection with nickel-plated endcaps, Eaton ensures robust terminations and long-term durability, enabling lower maintenance and higher uptime for critical systems. This makes it a strong fit for manufacturers seeking dependable, easy-to-service protection with minimal installation effort.

FAQs
Yes. The BAF-2-1/2 is specified with ferrule-end x ferrule-end connections, facilitating secure, repeatable terminations in standard panel wiring. Its compact footprint (0.41 in W x 0.41 in D) and 1.5 in height fit common enclosure footprints, simplifying installation and reducing panel crowding.
The fuse provides 10 kAIC interrupt rating at 125 VAC and 100 AIC at 250 VAC, ensuring rapid fault clearance for both low- and higher-energy events while protecting connected devices and wiring from damage.
Best suited for control panels, instrumentation, and small-load circuits where fast protection is required and space is at a premium. Its 2.5 A rating and 250 V operation support a wide range of automation sensors, PLC I/O, and small actuators, with reliable protection and easy integration.
The BAF-2-1/2 fuse is CE Marked, indicating compliance with European safety standards. This provides confidence for European installations and projects requiring formal safety conformance within automation and electrical protection applications.
The device is non-indicating, so status is monitored through system-level indicators or diagnostics. It serves as a replacement option for legacy F15B fuses and comes in standard packaging for easy stocking. For reliability, keep spare fuses on hand and ensure ferrule-term wiring is properly crimped to maintain secure connections.
