1sna399228r1400 – d2,5/5,snt2,ado
TE Connectivity D2.5/5.SNT2.ADO 1SNA399228R1400 is a compact 10 A, 320 V disconnect terminal block combining ADO and screw-clamp connections with a hand-operated knife blade and two 2 mm test sockets for industrial control circuits.
Why Choose the TE Connectivity D2.5/5.SNT2.ADO 1SNA399228R1400 Disconnect Terminal Block?
The TE Connectivity D2.5/5.SNT2.ADO 1SNA399228R1400 is a compact disconnect terminal block with ADO and screw-clamp connections designed for industrial control, automation and test circuits. Part of the established TE Connectivity Entrelec ADO System terminal block range, it combines fast ADO conductor termination with a conventional screw-clamp connection and a manually operated disconnect knife blade.
The D2.5/5.SNT2.ADO incorporates two 2 mm test sockets, allowing convenient access for electrical measurement, commissioning and fault finding. Its hand-operated disconnect blade enables a circuit to be isolated without removing the connected conductors, making the terminal particularly useful for control, instrumentation and maintenance applications.
With an IEC rated current of 10 A, rated voltage of 320 V and rated cross-section of 1 mm², the 1SNA399228R1400 provides reliable circuit connection and isolation in a compact 5 mm wide format. Its DIN rail mounting and compatibility with TH35 rails make it straightforward to integrate into densely populated industrial control cabinets.
