1sna031838r1200 – bnms-f500ma/125v-1

Why Choose the TE Connectivity BNMS-F500mA/125V-1 Fuse Plug?

The TE Connectivity / Entrelec BNMS-F500mA/125V-1 1SNA031838R1200 is an output fuse plug from the INTERFAST MS interface range, designed to provide replaceable fuse protection within industrial control and automation circuits. It is rated for 125 V circuits and incorporates a 500 mA fuse, providing a convenient protective function directly within a compatible modular interface system.

The BNMS-F500mA/125V-1 is the output fuse plug configuration within the BNMS fuse and strap plug family. By incorporating circuit protection into a removable plug-in component, it enables individual control or signal circuits to be protected without requiring a separate panel-mounted fuse holder, helping maintain compact and organised control-panel layouts.

Designed for professional industrial installations, the module uses a grey plug housing for straightforward identification and can be removed when fuse inspection or replacement is required. Its combination of 125 V voltage rating and 500 mA fuse rating makes it suitable for protecting compatible low-current output circuits in PLC, machine-control and process automation systems.

Key Advantages

• 500 mA fuse protection for compatible low-current circuits.
• Rated for use in circuits up to 125 V.
• Output fuse plug configuration for modular control interfaces.
• Plug-in construction allows convenient fuse inspection and replacement.
• Helps protect downstream wiring and equipment against excessive current.
• Eliminates the need for a separate fuse holder in suitable interface applications.
• Part of the established TE Connectivity / Entrelec INTERFAST MS connection system.

Reliable Plug-In Circuit Protection

The BNMS-F500mA/125V-1 provides localised overcurrent protection directly within a compatible interface assembly. Its 500 mA fuse can interrupt excessive current before it causes damage to appropriately rated downstream wiring or equipment, making the plug useful for protecting sensitive control and signal circuits.

Using a removable fuse plug also simplifies maintenance compared with permanently integrated protection devices. Technicians can access the protective element at the interface point during inspection and troubleshooting, while the modular INTERFAST MS architecture helps maintain an organised and space-efficient control cabinet.

Typical Applications

• PLC output circuit protection.
• Industrial automation control panels.
• Low-current control and signal circuits.
• Machine and production-line control systems.
• INTERFAST MS interface installations.
• Process control and instrumentation panels.
• Factory automation equipment.
• Electrical control cabinets requiring modular fuse protection.
