FAQs
Install BK/ATC-2 by inserting the blade-end into a compatible ATC fuse holder. Confirm the panel space is sufficient for a 0.76 inch depth fuse, and ensure the circuit operates at 32 Vdc with a 2 A rating. Use proper torque-free seating to avoid blade damage and verify quick-replaceability during maintenance.
The BK/ATC-2 is rated for 2 A, at 32 Vdc, with an interrupt rating of 1 kAIC. It is a non-indicating blade fuse with a gray housing, designed for ATC blade-end compatibility in DC protection scenarios within compact panels.
Yes, BK/ATC-2 is RoHS compliant. The datasheet notes RoHS compliance but does not list CE, UL, or SIL certifications; for current or additional certifications, contact Eaton’s factory support to verify availability for your region and application.
BK/ATC-2 is suitable for low-voltage DC protection in control panels, DC power rails, and industrial automation equipment. Its compact size and ATC blade compatibility support easy retrofits in existing panel boards and automotive-like DC distributions within manufacturing environments.
BK/ATC-2 uses a blade-end design with a gray color-coded housing for quick visual identification, 2 A rating, 32 Vdc rating, and a 1 kAIC interrupt rating. Compared to larger or higher-rated ATC fuses, it offers compact form factor, faster replacement in tight spaces, and predictable protection for sensitive DC circuits in automation gear.
