The 3048399 is a fuse modular terminal block designed for overcurrent protection in industrial systems. It utilizes a screw connection method that accommodates conductor cross-sections from 1.5 mm² to 25 mm² (16-4 AWG). This block is rated for a nominal current of 32 A and a nominal voltage of 690 V, and it is compatible with 10.3 x 38 mm glass cartridge fuses. A key feature is the integrated LED that indicates when a fuse has blown, simplifying troubleshooting. Designed for mounting on NS 35/7,5 and NS 35/15 DIN rails, its 18 mm width makes it a space-efficient solution for control cabinets and distribution panels.
