Description
Product Overview
The Bussmann HEB AA fuse holder is engineered as a compact, in‑line protective device designed for 13/32″ × 1‑1/2″ supplemental fuses. Constructed from high‑temperature resistant polymer and reinforced metal terminals, the unit measures 2.3 × 2.2 × 1.3 inches and weighs just 1.36 oz, making it easy to integrate into tight panel spaces while delivering robust electrical isolation. Its design follows industry‑standard dimensions, ensuring seamless fit within existing breaker panels, load centers, and control cabinets.
Compatibility is a core strength of the HEB AA series. The holder accepts a wide range of Bussmann supplemental fuses, providing flexibility for various current ratings and voltage requirements. An optional insulating boot can be added to render the assembly submersible, extending its use to damp or wet environments where additional protection against moisture ingress is essential. This modular approach lets users tailor the product to specific installation conditions without compromising safety.
Durability is reinforced through a sealed, impact‑resistant housing that meets UL and IEC standards for electrical safety. The internal contacts are silver‑plated to reduce resistance and prevent corrosion over the product’s lifecycle. With a National Stock Number of 5920‑00‑090‑0839, the HEB AA holder is tracked in supply chains worldwide, guaranteeing availability for maintenance and replacement programs. Its non‑breakaway characteristic ensures the fuse remains securely seated during normal operation, eliminating accidental disengagement that could lead to system downtime.
Installation is straightforward thanks to multiple terminal options, including screw‑type, spring‑loaded, and quick‑connect variants. Detailed wiring diagrams accompany each terminal style, allowing electricians to achieve a secure, low‑impedance connection in minutes. The holder’s low profile also supports panel density, enabling designers to maximize space efficiency while maintaining clearances required by code. All components are labeled for easy identification, reducing the risk of mis‑installation and simplifying future troubleshooting.
Bussmann’s reputation for quality and reliability underpins the HEB AA fuse holder. With over 30 years of experience in circuit protection, the brand delivers products that consistently pass rigorous testing for overload, short‑circuit, and environmental resilience. Customer reviews average 4.6 out of 5 stars, reflecting confidence in performance and long‑term value. By choosing this holder, users benefit from a proven solution backed by a global support network and comprehensive warranty coverage.

Usage
The HEB AA fuse holder excels in industrial settings where precise component protection is required. It is commonly installed in motor control centers, transformer bays, and equipment racks to safeguard sensitive electronics, sensors, and control circuitry from over‑current events that exceed the rating of the primary circuit breaker. Its compact form factor allows it to be positioned close to the protected device, reducing lead length and improving response time.
For applications exposed to moisture, such as outdoor pump stations, water treatment facilities, or marine environments, the optional submersible boot transforms the holder into a fully sealed unit. This adaptation meets IP68 standards, preventing water ingress even when the holder is immersed for extended periods. Engineers appreciate the ability to reuse the same holder across dry and wet installations, simplifying inventory management and reducing overall system cost.
Maintenance crews benefit from the holder’s clear visual indicators. The transparent housing reveals the fuse status at a glance, enabling rapid verification of fuse integrity during routine inspections. When a fuse needs replacement, the non‑breakaway design ensures the holder remains firmly attached to the panel, eliminating the need to re‑mount the device and minimizing downtime. This ease of service contributes to higher equipment availability and lower total cost of ownership.

FAQ
Can the HEB AA holder be used with fuses from other manufacturers?
Yes, the holder is compatible with any 13/32″ × 1‑1/2″ supplemental fuse that meets the same physical dimensions and voltage rating. However, using Bussmann‑branded fuses ensures optimal contact performance and maintains the warranty coverage.
What does “non‑breakaway” mean for this fuse holder?
Non‑breakaway indicates that the holder’s internal contacts are designed to stay engaged with the fuse under normal operating conditions, even when the panel is subjected to vibration or minor impacts. This prevents the fuse from unintentionally disconnecting, which could otherwise cause an open circuit and equipment downtime.
How do I install the optional submersible boot?
The boot is a separate silicone‑filled component that slides over the holder’s housing and seals with a gasket. Installation involves removing the holder’s protective cover, positioning the boot, and re‑securing the cover. Detailed step‑by‑step instructions are included in the product manual, and no additional tools are required.
Is the HEB AA holder suitable for high‑current applications?
The holder itself does not limit current; it is the fuse that determines the protection level. Choose a supplemental fuse with the appropriate current rating for your application, and the holder will safely carry the load while providing the intended over‑current protection.
What certifications does this product have?
The HEB AA fuse holder complies with UL 508A and IEC 60947‑4‑1 standards for industrial control equipment. It also meets RoHS restrictions, ensuring it is free from hazardous substances and suitable for environmentally conscious installations.
