Bussmann Series Medium Voltage fuses and accessories are engineered for the protection of power distribution systems operating from 2.4 kV to 38 kV. These current-limiting fuses are designed to interrupt fault currents rapidly, minimizing thermal and mechanical stress on downstream equipment. Key technical parameters include rated voltage, continuous current ratings from 0.5 A to 200 A, and interrupting ratings up to 80 kA symmetrical. The range covers E-rated and R-rated fuses, as well as motor-starting fuses, all housed in durable ceramic or fiberglass bodies with silver or copper elements. Accessories include fuse holders, disconnect switches, and indicating mechanisms for visual status.
These fuses are critical in industrial substations, transformer protection, motor control centers, and capacitor bank circuits. They are commonly installed in medium voltage switchgear, pad-mounted transformers, and underground distribution systems. Sectors such as mining, oil and gas, water treatment, and renewable energy plants rely on these components for reliable overcurrent protection in harsh environments.
Subcategories include E-Rated Medium Voltage Fuses (e.g., 5.5 kV, 15.5 kV, 25.8 kV), R-Rated Motor Start Fuses, and Backup Current-Limiting Fuses. Key article codes often follow patterns like EA62-XXX-XX, where the first digits indicate voltage class and the last digits denote current rating. For example, EA62-15.5-100E represents a 15.5 kV, 100 A E-rated fuse. Accessories such as fuse clips, mounting bases, and blown fuse indicators are also available.
Partnering with Electric Automation Network ensures access to genuine Bussmann products with real-time pricing and global express shipping. Our team of specialized engineers provides technical support for fuse selection, coordination studies, and replacement recommendations. We offer detailed documentation including time-current curves and application notes to streamline your project.
All ratings we receive from the items we offer are real and verified. A small gesture, but a lot of value. That's why we thank you for that minute you invest in leaving us your opinion and qualification about the products, because it helps us to continue improving and to offer you a service of even higher quality.
