Bussmann BKMDA-V BK/MDA-V Series Time-Delay Ceramic Fuse, Ferrule End

Bussmann BK/MDA-V Series Time-Delay Ceramic Fuse, Ferrule End

The Bussmann BK/MDA-V Series Time-Delay Ceramic Fuse from Eaton Bussmann is a ferrule end x ferrule end fuse built around a .25 in. diameter ceramic tube body with nickel-plated brass endcaps, designed to protect electronic circuits from overcurrent conditions. This time-delay (slow-blow) fuse is rated 250 Vac, 32 Vdc (self certified) and is engineered with a controlled response — up to 60 minutes at 135% of rated current and 120 seconds at 200% — to ride through momentary inrush without nuisance opening. The BK/MDA-V Series is available in 1A, 3A, 5A, 6A, and 7A ratings, allowing electronic assemblies of varying current draw to be matched with the correct protection level. Its axial-lead, copper tinned wire construction and non-indicating design suit standard ferrule-style fuse holders.

Key Features

• Compact Ceramic Body: .25 in. diameter ceramic tube construction in a space-saving footprint for electronic assemblies.
• Durable Construction: Nickel-plated brass endcaps resist corrosion and provide a stable, low-resistance connection point.
• Ferrule End Connection: Ferrule end x ferrule end configuration with axial leads of copper tinned wire for compatibility with standard ferrule-style fuse holders.
• Voltage Rating: Rated 250 Vac, 32 Vdc (self certified) for use in low-voltage electronic circuits.
• Time-Delay Response: Opens in 60 minutes maximum at 135% of rated current and 120 seconds maximum at 200%, allowing brief inrush current without nuisance blowing.
