Why Choose the TE Connectivity ES8-CG Green Railway Disconnect Terminal Block?
The TE Connectivity 1SNA400014R2700, identified as ES8-CG Green, is a railway disconnect terminal block with screw-clamp connections and a quarter-turn push-turn disconnect mechanism. Part of the Entrelec SNA HD railway range, it is designed for control, measurement and isolation circuits where secure conductor termination and convenient circuit disconnection are required.
The ES8-CG is particularly suited to demanding railway environments and incorporates a self-cleaning displacement system with a protective plastic cover, helping maintain reliable operation in corrosive or dusty atmospheres. The push-turn knob provides controlled disconnect operation and can be sealed in the open position, supporting safe maintenance and circuit-isolation procedures.
With an 8 mm spacing, 6 mm² rated cross-section and screw-clamp capacity up to 10 mm² rigid or 6 mm² flexible, the ES8-CG provides a robust interface for railway wiring. Built-in test facilities simplify electrical checking without dismantling the terminal assembly, while mounting compatibility with G32, TH35-7.5 and TH35-15 rails provides installation flexibility.

Reliable Disconnect and Test Connections for Railway Systems
Railway electrical systems require connection components capable of supporting reliable maintenance and testing under demanding environmental conditions. The ES8-CG addresses these requirements with a protected disconnect mechanism, robust screw-clamp conductor connections and a self-cleaning contact arrangement intended to perform reliably in environments affected by dust or corrosion.
The quarter-turn push-turn knob allows the circuit to be disconnected without removing conductors from the terminal. The ability to seal the mechanism in its open position assists controlled isolation procedures, while the integrated test facility allows technicians to perform measurements directly at the terminal during commissioning, troubleshooting and scheduled railway maintenance.
Typical Applications
- Railway rolling-stock electrical systems.
- Train control and auxiliary electrical panels.
- Rail vehicle measurement and test circuits.
- Disconnect and isolation circuits.
- Electrical installations exposed to dust or corrosive atmospheres.
- Railway equipment cabinets requiring accessible circuit testing and maintenance.
