Eaton BBS-4 Bussmann Fuse - CE 600V 10 kAIC FAST-ACTING
Part Number: BBS-4
Quick Summary
Eaton BBS-4 fuse protects circuits with fast-acting interruption in industrial control panels. Engineers often contend with cramped panel spaces and nuisance trips when using lower-current devices. This CE-marked component delivers 600 V ratings and 10 kAIC interrupt capacity, ensuring reliable protection for demanding electrical systems. With ferrule-end connections and nickel-plated endcaps, it installs quickly and stays secure in dense enclosures. The 4 A rating fits selective coordination strategies in automation equipment, while standard packaging streamlines procurement. In practice, using the BBS-4 reduces downtime, simplifies stocking for spares, and supports consistent safety margins across controls and power distribution networks. Its non-indicating fuse indicator keeps panel aesthetics clean while maintenance cycles remain predictable.

FAQs
The BBS-4 uses ferrule-end x ferrule-end connections, which provide secure, vibration-resistant terminations in standard Bussmann fuse blocks. When installing, ensure correct orientation and seating in compatible panels, verify endcap cleanliness, and use crimp-compatible ferrules to prevent loosening under operation. Proper torque on mounting hardware helps maintain reliable contact and minimizes contact resistance over time.
The BBS-4 is rated at 4 A with an interrupt rating of 10 kAIC at 600 VAC and a voltage rating of 600 V. This combination supports high fault-current scenario protection while enabling safe operation within standard automation equipment and panel boards, ensuring fast clearance of faults without compromising overall system integrity.
Yes. The BBS-4 is intended for control panel protection in automation environments. Its compact size, ferrule-end terminations, 4 A rating for selective coordination, and 10 kAIC interrupt capacity at 600 VAC make it ideal for safeguarding relays, controllers, and drives while minimizing nuisance trips and space requirements.
The BBS-4 is CE marked, confirming compliance with European safety and performance standards. In practice, this supports regulatory acceptance across EU markets and aligns with common electrical installation practices in automation. If your project requires additional certifications beyond CE, verify compatibility with local regulatory requirements and consult the Eaton datasheet for guidance.
By delivering fast-acting fault clearance and reliable protection, the BBS-4 minimizes unplanned outages and component damage. Its compact design, ferrule-end terminations, and standard packaging simplify replacement during routine maintenance and spares management. In combination with durable nickel-plated endcaps and silver-plated caps, it delivers long service life, reducing inventory diversity and accelerating field service response.
