1sna290071r0100 – d2,5/5,sb,2l
TE Connectivity D2.5/5.SB.2L 1SNA290071R0100 is a grey 5 mm-wide spring-clamp disconnect terminal block with a 2.5 mm² rated cross-section, 10 A rated current and 500 V rated voltage for industrial DIN rail installations.
Why Choose the TE Connectivity D2.5/5.SB.2L 1SNA290071R0100 Disconnect Terminal Block?
The TE Connectivity / Entrelec D2.5/5.SB.2L 1SNA290071R0100 is a grey spring-clamp disconnect terminal block designed for industrial control, automation and electrical distribution applications. Part of the SNA spring terminal range, it combines compact DIN rail installation with a disconnect function that allows circuits to be isolated using a compatible plug component.
Spring-clamp connection technology provides consistent conductor contact pressure independently of installer-applied screw torque, while automatic compensation helps maintain reliable electrical contact over time. The terminal also features front wiring entry for convenient conductor access during panel assembly, testing and maintenance.
The D2.5/5.SB.2L has a rated cross-section of 2.5 mm², a rated current of 10 A and a rated voltage of 500 V. Its compact 5 mm spacing and compatibility with TH35 DIN rails make it well suited to space-conscious industrial terminal assemblies requiring accessible circuit disconnection.

Accessible Spring-Clamp Circuit Disconnection
Spring-clamp terminal technology maintains conductor contact through mechanically controlled spring force, helping provide repeatable electrical connections without dependence on installer-applied screw torque. This makes the technology particularly useful in industrial panels where installation efficiency and dependable long-term connections are important.
The D2.5/5.SB.2L adds a disconnect function to this spring-clamp platform, allowing a circuit to be interrupted through a compatible plug component. Combined with front-entry wiring, 5 mm spacing and standard DIN rail mounting, this provides an accessible solution for circuits that may require isolation during commissioning, testing, troubleshooting or maintenance.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Measurement and instrumentation circuits.
- Machine-building electrical systems.
- Process-control installations.
- Circuits requiring convenient testing or isolation.
- DIN rail-mounted terminal assemblies.
