Bussmann GDA2A GDA Series 2A Fast-Acting Small Dimension Ceramic Fuse 250VAC

The Bussmann GDA2A is a fast-acting, small dimension ceramic fuse from Eaton's Bussmann GDA Series, engineered for reliable overcurrent protection in sensitive electronic circuits and instrumentation applications.

Key Features:

• Current Rating: 2 Amperes
• Voltage Rating: 250 VAC / 32 VDC (self-certified)
• Interrupt Rating: 1,500 Amperes (high breaking capacity)
• Body Style: Cylindrical ceramic, 5.2 mm diameter x 20 mm length (5x20 mm form factor)
• Terminal Type: Ferrule — fits standard fuse clips and holders
• Element Type: Single element, non-indicating, non-rejection
• Response Type: Fast-acting (fast-blow) — opens rapidly under overload and short circuit conditions
• Design Standard: IEC 60127-2 compliant
• Mounting: Clip or fuse holder/block mounting

The GDA2A features a ceramic body construction that provides superior heat resistance compared to glass fuses, making it well-suited for demanding electronic protection applications. As a fast-acting fuse, it is highly sensitive to changes in current flow and provides immediate response to overloads and short circuits, helping protect precision instruments and electronic equipment from damage.

Compatible with Bussmann Series fuse holders, blocks, and fuse clips. Axial lead versions are also available for through-hole PCB installation. The standard 5x20 mm cylindrical form factor ensures broad compatibility with common fuse holders used across industrial, commercial, and electronic applications.
