1sna031821r0100 – bnms-f125ma/125v-1

Why Choose the TE Connectivity BNMS-F125mA/125V-1 Fuse Plug?

The TE Connectivity BNMS-F125mA/125V-1, manufacturer part number 1SNA031821R0100, is an industrial output fuse plug designed for compatible Entrelec Interfast MS interface systems. It provides localised circuit protection in a compact plug-in format, allowing a protected circuit to be incorporated directly into the modular interface assembly.

This BNMS fuse plug is rated at 125 mA and 125 V, making it suitable for low-current industrial control and signal circuits requiring dedicated fuse protection. The plug-in construction provides a convenient method of adding or servicing protection without replacing the complete compatible terminal or interface assembly.

With a narrow width of just 5 mm, a height of 34.5 mm and a depth of 38 mm, the BNMS-F125mA/125V-1 supports high-density installations within industrial electrical cabinets. Its compact grey housing and approximately 4 g net weight make it a practical protective component for PLC, machinery and automation control applications.

Compact Fuse Protection for Industrial Control Systems

Fuse plugs provide a convenient method of protecting individual control and signal circuits against excessive current. Integrating the fuse function directly into a modular interface system keeps protection close to the associated circuit and can make fault investigation and component replacement easier than installations using remotely located protective devices.

The BNMS-F125mA/125V-1 combines a 125 mA fuse rating with a compact plug-in design intended for compatible Entrelec interface equipment. This makes it particularly useful where sensitive low-current circuits require dedicated protection while panel space, wiring organisation and straightforward maintenance remain important.

Typical Applications

• Industrial control and signal circuit protection.
• PLC input and output interface systems.
• Industrial control panels and electrical cabinets.
• Machine control and factory automation systems.
• Low-current instrumentation and signalling circuits.
• Compatible Entrelec Interfast MS interface installations.
