1sna399856r0200 – d4/8,sflt2,i,ado
TE Connectivity D4/8.SFLT2.I.ADO 1SNA399856R0200 is a grey 6.3 A, 500 V ADO-to-screw-clamp fuse terminal block for 5 × 20 mm and 5 × 25 mm fuses with a 110–230 V AC neon blown-fuse indicator and two 2 mm test sockets.
Why Choose the TE Connectivity D4/8.SFLT2.I.ADO 1SNA399856R0200 Fuse Terminal Block?
The TE Connectivity D4/8.SFLT2.I.ADO 1SNA399856R0200 is a grey fuse terminal block with ADO and screw-clamp connections, designed to combine circuit protection, fault indication and convenient electrical testing in industrial control systems. It accepts 5 × 20 mm and 5 × 25 mm fuses and incorporates a blown-fuse indicator for rapid identification of a failed circuit.
This D4/8 variant features a 110–230 V AC neon blown-fuse indicator together with two 2 mm test sockets. The hybrid connection arrangement combines TE Connectivity's ADO insulation-displacement system with a conventional screw clamp, allowing compatible conductors to be terminated using the most appropriate connection method on each side.
With an IEC rated current of 6.3 A, rated voltage of 500 V and impulse withstand voltage of 6 kV, the D4/8.SFLT2.I.ADO is engineered for professional panel building and automation applications. Its 8 mm spacing, IP20 protection and compatibility with TH 35 DIN rails support compact, organised fuse-protected circuit distribution.

Integrated Fuse Protection, Fault Indication and Testing
Fuse terminal blocks allow individual control and auxiliary circuits to be protected directly at the terminal strip while retaining convenient access for maintenance. The D4/8.SFLT2.I.ADO accepts 5 × 20 mm and 5 × 25 mm fuses, while its 110–230 V AC neon indicator makes it easier to identify a circuit with a blown fuse during troubleshooting.
Two integrated 2 mm test sockets provide accessible points for measurement and diagnostics. Combined with ADO insulation-displacement termination on one side and a screw clamp on the other, this configuration provides a versatile interface for protected control circuits while maintaining an organised 8 mm-wide terminal arrangement.
Typical Applications
- Fuse-protected industrial control circuits.
- PLC and automation control panels.
- Machine-building electrical systems.
- Instrumentation and monitoring circuits.
- Switchgear and electrical distribution assemblies.
- Circuits requiring visible blown-fuse indication.
- DIN-rail systems requiring convenient test access.
