Bussmann 5CLE1-80E E-Rated Current Limiting Fuse, 80A, 5.5 kV

Bussmann 5CLE1-80E E-Rated Current Limiting Fuse, 80A, 5.5 kV

The Bussmann 5CLE1-80E is an E-Rated current limiting power fuse engineered for demanding medium-voltage overcurrent protection applications. Rated 80A with a maximum voltage of 5.5 kV and backed by a 63 kA interrupt rating, the 5CLE1-80E is built to safely clear high-magnitude fault currents while limiting let-through energy to help protect connected transformers, motors, switchgear, and other downstream equipment. As part of the Bussmann electrical protection lineup, this current limiting fuse delivers dependable, code-focused performance for industrial and commercial power distribution systems where consistent, predictable fuse operation is essential. Because mounting configurations for E-rated power fuses vary by application, Bussmann recommends consulting the factory before specifying mounting hardware for the 5CLE1-80E.

Key Features

• Amperage Rating: An 80A rating provides reliable, correctly sized overcurrent protection for medium-voltage power circuits and equipment.
• Maximum Voltage: Rated up to 5.5 kV, making the fuse suitable for medium-voltage power distribution equipment and systems.
