WAGO 2002-1671 2-Conductor Disconnect and Test Terminal Block with Push-in CAGE CLAMP, Gray

In control cabinets and distribution boxes, testing and isolating circuits without disrupting the wiring is a constant challenge. The WAGO 2002-1671 2-conductor disconnect and test terminal block solves this by providing a safe, tool-free way to separate the current path and insert test probes, all while keeping conductors securely clamped. Part of the TOPJOB® S series, this gray terminal block is engineered for DIN-rail mounting and handles up to 800 V and 20 A, making it a reliable choice for industrial automation, building technology, and panel building.

Who is it for

This terminal block is ideal for electricians, panel builders, and maintenance technicians who need to perform routine testing, fault finding, or signal isolation in control circuits. It suits applications where space is limited but safety and accessibility are paramount, such as machine control systems, PLC interfaces, and power distribution units.

Tips

For reliable connections, strip conductors to 9–11 mm and use ferrules on fine-stranded wires when required. To test a circuit, insert a standard 2 mm test plug into the socket—no need to remove the wire. Always ensure the terminal block is de-energized before performing any maintenance. For higher current applications, consider the 4 mm² variant.
