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.
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.

The ES8-CG is a green railway disconnect terminal block from the Entrelec SNA HD range, combining screw-clamp conductor connections with a quarter-turn push-turn disconnect mechanism and integrated test facilities.
The ES8-CG uses a quarter-turn push-turn knob to disconnect the electrical circuit. The mechanism can also be sealed in the open position to support controlled isolation during maintenance.
The screw clamps accept one rigid conductor from 0.5–10 mm² or one flexible conductor without ferrule from 0.5–6 mm² per clamp.
Yes. The ES8-CG incorporates an integrated test facility, allowing electrical measurements and diagnostic operations to be carried out conveniently at the terminal assembly.
The terminal block can be installed on G32, TH35-7.5 and TH35-15 mounting rails, providing flexibility when integrating it into railway electrical assemblies.
TE Connectivity / Entrelec SNA HD railway terminal blocks provide rolling-stock manufacturers, panel builders and railway engineers with robust connection, isolation and testing solutions engineered for dependable operation in demanding electrical environments.
