Description
Bussmann SC-20 Class G Fuse Overview
The Bussmann SC-20 is a 20-amp, 600VAC Class G current-limiting fuse engineered for reliable branch circuit protection in commercial and industrial HVAC and electrical applications. Class G fuses are a rejection-type design, meaning their physical dimensions are sized to prevent the installation of a higher-amperage fuse — a critical safety feature that eliminates the risk of overfusing.
