FAQs
Install BK/ATC-4 by aligning the blade ends with the ATC holder contacts and pressing firmly until fully seated. Ensure the enclosure is de-energized and space permits the 0.76 in length and 0.752 in height. Use the pink housing as a quick visual identifier to confirm the correct fuse type during assembly or service.
Yes. BK/ATC-4 is designed for standard Bussmann ATC blade fuse holders, offering straightforward replacement and reliable mating with common panel infrastructure. Its 4 A, 32 Vdc rating and 1 kAIC interrupt capacity provide predictable protection for DC circuits in automated equipment.
BK/ATC-4 is rated for 4 A continuous current, 32 Vdc maximum voltage, and 1 kAIC interrupt rating. These specifications support safe interruption of short-circuit currents in low-voltage DC circuits found in control panels and automation equipment.
BK/ATC-4 is RoHS compliant, helping meet environmental and regulatory requirements. For additional certifications such as CE listings, contact Eaton or the factory to discuss eligibility and potential paperwork necessary for your region and application.
The 2000-count packaging and bulk procurement reduce unit costs and reorder frequency, while the compact, non-indicating design minimizes panel footprint and maintenance time. Color-coded pink housing speeds identification, lowering downtime and improving serviceability across multi-site automation deployments.
