The TE Connectivity 1SNA116924R0200 BNF52 is a grey plug-in fuse holder component plug from the ENTRELEC SNA terminal block accessories range. Designed for compatible SNA switch terminal blocks, it provides a convenient means of adding fuse protection directly to a modular DIN rail terminal assembly without requiring a separate panel-mounted fuse holder.
The BNF52 is designed to accommodate standard 5 × 20 mm and 5 × 25 mm cartridge fuses, making it suitable for protection of industrial signal, control and auxiliary circuits. The plug-in format allows the fuse holder to be inserted into a compatible terminal block and removed when required for fuse inspection, replacement or maintenance.
With a compact width of approximately 7.9 mm and a grey insulating housing, the 1SNA116924R0200 integrates neatly with compatible ENTRELEC SNA terminal assemblies. It is a purpose-designed accessory for industrial panel builders requiring modular fuse protection with straightforward servicing and consistent terminal system compatibility.
Plug-in fuse holders allow circuit protection to be incorporated directly into compatible terminal block assemblies while retaining convenient access to the protective device. The BNF52 accepts standard 5 × 20 mm or 5 × 25 mm cartridge fuses, allowing the selected fuse characteristics to be matched to the requirements of the connected control, signal or auxiliary circuit.
When a fuse requires inspection or replacement, the BNF52 can be accessed without dismantling the permanent terminal wiring. This modular approach helps simplify commissioning and maintenance while keeping protection components organised within the DIN rail terminal assembly, making the 1SNA116924R0200 well suited to industrial machinery, automation and control-panel applications.
