The Keystone Electronics 3544-2 is a through-hole fuse block designed for miniature blade fuses (ATM series). It is rated for 20A continuous current at 500V AC, with a UL recognized current rating of 30A. The holder accommodates fuses measuring 0.433" x 0.152" and is configured for vertical orientation, single-circuit operation.
The insulator is made of Nylon 4/6 with a UL 94V-0 flammability rating, capable of operating from -50°C to +145°C. Contacts are brass with tin-nickel plating, 0.016" thick. The termination style is PC pin for through-hole soldering to a PCB.
This fuse block is suitable for automotive and industrial applications where reliable overcurrent protection is required. It is compatible with Littelfuse Mini 297/997 and Bussmann ATM series fuses. The compact design allows for efficient PCB layout in power distribution systems.
