1sna290151r0600 – d2.5/5.sb.4l spring terminal
TE Connectivity D2.5/5.SB.4L 1SNA290151R0600 is a grey 5 mm spring-clamp disconnect terminal block rated at 2.5 mm², 10 A and 500 V for DIN rail-mounted industrial control, automation and instrumentation wiring.
Why Choose the TE Connectivity D2.5/5.SB.4L 1SNA290151R0600 Spring Terminal?
The TE Connectivity / Entrelec D2.5/5.SB.4L 1SNA290151R0600 is a spring-clamp disconnect terminal block designed for reliable conductor connection and circuit isolation in industrial control panels, machinery and automation systems. Its disconnect function allows circuits to be separated using a plug arrangement, making the terminal particularly useful for testing, commissioning and maintenance applications.
Using spring-clamp connection technology, the D2.5/5.SB.4L provides consistent contact pressure without relying on installer-applied screw torque. Front wiring access supports convenient conductor installation within densely populated control cabinets, while the 5 mm width helps maximise available DIN rail space.
The terminal has a 2.5 mm² rated cross-section, 10 A rated current and 500 V rated voltage. It accepts flexible conductors from 0.12–2.5 mm² and rigid conductors from 0.12–4 mm², while its polyamide insulation, IP20 protection and UL 94 V-0 flammability classification support dependable use in demanding industrial electrical installations.

Reliable Spring-Clamp Circuit Isolation for Industrial Control Panels
Spring-clamp disconnect terminal blocks combine secure conductor termination with the ability to separate a circuit when testing, commissioning or maintenance is required. Spring technology maintains clamping pressure independently of installer-applied screw torque and provides automatic compensation for conductor movement, helping maintain dependable electrical contact over the service life of the installation.
The D2.5/5.SB.4L combines this connection technology with a compact 5 mm footprint and front conductor entry. Mounted on standard 35 mm DIN rail, it provides a practical solution for control, signal and instrumentation circuits where reliable wiring and convenient circuit disconnection are required.
Typical Applications
- Industrial control panels and electrical cabinets.
- Automation and PLC control systems.
- Signal and instrumentation wiring.
- Machine-building and OEM electrical systems.
- Circuits requiring convenient testing or isolation.
- Switchgear and electrical distribution assemblies.
- High-density DIN rail terminal installations.
