FAQs
The BK/ATC-20 is an ATC blade fuse designed for standard ATC fuse holders used in many automotive and industrial panels. To install, align the blade ends with the holder contacts, press firmly until the fuse seats, and ensure the colored housing is visible for quick verification. This minimizes installation errors and speeds up maintenance in control cabinets.
BK/ATC-20 is rated for 32 Vdc, 20 A with an interrupt rating of 1 kAIC. These specifications provide robust protection for DC circuits in control panels and power distribution modules, helping prevent damage from short circuits while enabling predictable replacement cycles and easier design validation.
Yes. The fuse is designed for 32 Vdc systems and 20 A protection, with a 1 kAIC interrupt rating, making it suitable for automotive controllers, industrial automation cabinets, and other DC protection applications. Its ATC blade format ensures compatibility with common fuse holders, streamlining integration in mixed environments.
BK/ATC-20 is RoHS compliant, aligning with global environmental and hazardous substance restrictions. While the data does not specify additional certifications, the RoHS status supports regulatory compliance in many industrial and automotive contexts, and the fuse’s color-coded housing aids rapid field verification.
By delivering reliable 32 Vdc protection at 20 A with a 1 kAIC interrupt rating, BK/ATC-20 reduces downtime from overcurrent events and lowers maintenance time due to easy replacement.
