1sna031828r1000 – bnms-f125ma/250v-4
TE Connectivity 1SNA031828R1000 BNMS-F125mA/250V-4 is a compact 125 mA, 250 V fuse plug from the Entrelec Interfast MS range for fused protection of industrial control and automation circuits.
Why Choose the TE Connectivity 1SNA031828R1000 BNMS-F125mA/250V-4 Fuse Plug?
The TE Connectivity 1SNA031828R1000, also identified as BNMS-F125mA/250V-4, is a compact 125 mA, 250 V fuse plug designed for use with modular terminal block and interface systems in industrial electrical control applications. Part of the established Entrelec Interfast MS range, it provides convenient fused circuit protection within compact control and automation assemblies.
Designed for industrial panel applications, the BNMS-F125mA/250V-4 combines a miniature fuse function with a plug-in format that supports modular circuit construction and maintenance. Its compact dimensions make it particularly useful where control-panel space is limited and individual signal or control circuits require low-current protection.
The fuse plug is rated at 125 mA and 250 V. With compact overall dimensions of approximately 34.5 × 5 × 38 mm (H × W × D) and a net weight of approximately 4 g, it provides a space-efficient solution for protected connections in industrial automation, instrumentation and control-panel systems.
