BK/AGC-40-R is a fast-acting, glass tube fuse from the AGC Series designed for circuit protection in low-voltage DC applications. The fuse features a 1/4" × 1-1/4" (6.3 mm × 32 mm) physical size with nickel-plated brass endcaps and is rated for 40A at 32V DC with an 80A interrupting rating. It exhibits fast-acting characteristics with opening times of 60 minutes maximum at 135% of rated current and 120 seconds maximum at 200% of rated current, meeting UL standard 248-14. The RoHS-compliant version is suitable for applications requiring reliable overcurrent protection in automotive, industrial control, and low-voltage power distribution systems where fast response to fault conditions is essential.
