TE Connectivity 1SNA031825R0500 BNMS-F2A/250V-2 is a 2 A, 250 V grey fuse plug designed to provide compact overcurrent protection in compatible Entrelec Interfast MS terminal and industrial control systems.
The TE Connectivity 1SNA031825R0500, also designated BNMS-F2A/250V-2, is a compact 2 A, 250 V fuse plug designed for use with compatible Entrelec Interfast MS terminal and interface systems. It provides convenient localised overcurrent protection within modular industrial control and automation assemblies, allowing circuit protection to be integrated directly at the interface or terminal level.
The BNMS-F2A/250V-2 has a rated fuse capacity of 2 A at 250 V. Its plug-in format allows a compatible circuit to be protected without requiring a separate standalone fuse holder, helping maintain a compact, organised and serviceable electrical panel layout.
Designed for the Entrelec Interfast MS system, the BNMS-F2A/250V-2 is identified as a grey fuse plug and is suitable for compatible R500-series interface and component-holder arrangements. The removable plug format provides convenient access to the protective element during commissioning, inspection and maintenance of industrial control equipment.
Fuse plugs provide a convenient method of incorporating overcurrent protection directly into modular terminal and interface assemblies. If current exceeds the designed fuse rating, the fuse interrupts the circuit, helping protect associated wiring and equipment against the effects of excessive current.
The TE Connectivity BNMS-F2A/250V-2 combines a 2 A current rating with a 250 V voltage rating in a removable plug format. Within compatible Interfast MS assemblies, this approach supports compact panel construction while providing convenient access for fuse inspection and replacement during maintenance.
