1sna116966r1400 – bouchon bnf652 d1 gris v2

Why Choose the TE Connectivity BNF652 D1 1SNA116966R1400 Fuse-Holder Plug?

The TE Connectivity 1SNA116966R1400, manufacturer designation BNF652 D1 and also identified as BOUCHON BNF652 D1 GRIS V2, is a grey plug-in fuse holder with a 48 V AC/DC LED blown-fuse indicator for compatible ENTRELEC SNA terminal blocks. It provides replaceable fuse protection together with visual fuse-status indication in industrial control, automation and electrical panel applications.

The BNF652 D1 is designed for 5 × 20 mm and 5 × 25 mm cartridge fuses and has a compact 6 mm thickness. The integrated LED provides a clear indication when the protected fuse has operated, helping maintenance personnel identify affected circuits quickly and reducing diagnostic time within densely populated control cabinets.

Designed as an accessory for compatible M4/6.D2.SB, M4/6.SB and M4/6.SBT.4A terminal blocks, the 1SNA116966R1400 forms part of the established ENTRELEC SNA passive connection system. Its plug-in construction allows convenient fuse replacement and servicing while retaining the modular format required for professional DIN rail terminal assemblies.

Visual Fuse Protection for Industrial Terminal Circuits

Fuse-holder plugs provide a convenient way to add replaceable circuit protection to compatible modular terminal blocks. The TE Connectivity BNF652 D1 combines this function with a 48 V AC/DC LED indicator, allowing an operated fuse to be identified visually without individually removing and testing each fuse during initial troubleshooting.

The ability to accommodate both 5 × 20 mm and 5 × 25 mm cartridge fuses gives the BNF652 D1 flexibility across a range of protected control and signal circuits. Its plug-in design also supports straightforward servicing, while compatibility with established ENTRELEC SNA terminals makes it suitable for both existing terminal assemblies and new industrial panel designs.

Typical Applications

• 48 V AC/DC fused control circuits.
• Industrial control and automation panels.
• PLC input and output circuit protection.
• Machine control cabinets.
• Instrumentation and monitoring circuits.
• Signal and auxiliary circuit protection.
• Electrical distribution and marshalling panels.
• ENTRELEC SNA fuse terminal assemblies.
