H326.175P

The **Littelfuse SLO-BLO® Ceramic Fuse H-PACK .175A (SKU: H326.175P)** is a high-performance, time-delay fuse engineered to deliver superior overcurrent protection in demanding industrial and electronic applications. Designed with a rugged ceramic body, this fuse combines exceptional thermal stability, high interrupting ratings, and elevated voltage ratings—making it an ideal choice for environments where sustained high-current loads are expected. Manufactured in compliance with **UL Standard 248-14**, the H326.175P ensures adherence to the most stringent safety and reliability benchmarks, providing engineers and technicians with a trusted solution for critical protection needs. **Key Features and Benefits:** - **Ceramic Body Construction**: Unlike traditional glass or plastic fuses, the ceramic body of the SLO-BLO fuse enables superior heat dissipation and mechanical strength, allowing it to withstand extreme operating conditions. This construction is particularly beneficial in high-temperature environments, such as power supplies, motor controls, and industrial machinery, where conventional fuses may fail prematurely. - **High Interrupting Ratings**: With its ability to safely interrupt high fault currents, the H326.175P is well-suited for applications prone to transient surges or short circuits. This feature minimizes the risk of catastrophic equipment failure and reduces downtime in critical systems. - **Time-Delay (SLO-BLO) Operation**: The time-delay characteristic of this fuse allows it to tolerate temporary overloads and inrush currents—common in inductive loads like motors, transformers, and solenoids—without nuisance tripping. This makes it an excellent choice for applications where momentary current spikes are expected but sustained overcurrent must be prevented. - **Versatile Mounting Options**: Available in both **cartridge and axial lead formats**, the H326.175P offers flexibility for integration into a wide range of panel designs and PCB layouts. The axial lead version is particularly useful for through-hole mounting in compact electronic assemblies, while the cartridge format provides ease of replacement in industrial control panels. - **Environmental Compliance**: Fully **RoHS-compliant and lead-free**, the SLO-BLO ceramic fuse aligns with global sustainability initiatives and regulatory requirements. This ensures compatibility with modern manufacturing processes and reduces environmental impact without compromising performance. **Typical Applications:** The Littelfuse SLO-BLO Ceramic Fuse H-PACK .175A is widely utilized across multiple industries where reliable overcurrent protection is paramount. Common applications include: - **Power Supplies and Converters**: Protecting sensitive electronic components from overcurrent events in switch-mode power supplies (SMPS), DC-DC converters, and battery management systems. - **Industrial Control Systems**: Safeguarding PLCs, motor starters, and control panels from fault conditions in manufacturing, automation, and robotics applications. - **Telecommunications Equipment**: Providing surge protection for network infrastructure, including routers, switches, and base stations, where transient currents can damage sensitive circuitry. - **Automotive and Transportation**: Used in vehicle charging systems, traction inverters, and auxiliary power units (APUs) to protect against short circuits and overloads in harsh operating conditions. - **Renewable Energy Systems**: Deployed in solar inverters, wind turbine controllers, and energy storage systems to ensure safe operation under fluctuating load conditions. **Why Choose Littelfuse?** Littelfuse is a global leader in circuit protection solutions, with over a century of innovation and expertise in fuse technology.
