The test-disconnect terminal blocks offer a high degree of convenience for all the necessary test circuits in secondary current transformer circuits. With six universal function shafts, the test-disconnect terminal blocks provide the highest level of functionality and flexibility in potential distribution. You can protect connected current transformers reliably thanks to connector versions with integrated leading short-circuit contact.

Test-disconnect terminal blocks
Configure your individual design of measuring transducer sets. In addition to selecting suitable transformer terminal blocks, the accessories for testing and short-circuiting the current transformers can be positioned according to the application.
The Push-X function terminals also allow the tool-free wiring of flexible conductors. In addition, the integrated disconnect zones enable signals to be disconnected easily. The TG basic disconnect terminal blocks also offer the option of safely integrating function plugs.
Transformer disconnect terminal blocks
The current transformer terminal blocks allow you to freely select the connection technology. A patented triple function shaft was used in the design of the current transformer terminal blocks. This guarantees the compact design and flexibility of the terminal blocks. The integrated section disconnector on the terminal blocks switches safely between the switching states using a screwdriver on the orange disconnect lever. Latching is integrated in the end positions and optional switching locks are available to ensure that this switching state is not changed inadvertently. In addition to the disconnect terminal blocks, feed-through terminal blocks and PE terminal blocks of the same shape complete the product range.
XTVMEA 6 is the new transformer terminal block in the terminal block range. The new MEA terminal block is equipped with the innovative Push-X connection technology. This means that the conductors can be wired almost effortlessly with just one hand. Another advantage of the new transformer terminal blocks is the type of transformer short circuit. The current transformers can be short-circuited easily and safely, due to special short-circuit bridges and the use of coupling modules for the section disconnectors. By switching over the coupled section disconnectors, the current transformer is automatically short-circuited in line with the “make before break” principle before the current transformer is disconnected on both sides. The decoupling of the actuation levers also allows you to open the circuit on one side. In addition to the XTVMEA 6 test-disconnect terminal block, the new MEA series includes a feed-through terminal block of the same shape and a ground terminal.
PTME test-disconnect terminal blocks
You can safely and conveniently short-circuit the ME series measuring transducers using the plug-in bridge bars and a standard screwdriver. The bridge bars can be positioned on both sides of the disconnect point in the bridge shaft and latched in place. In addition to the short-circuit bridge version, plug-in terminal blocks with short-circuit plugs can also be used. When the plug is pulled out, an integrated metal switching device ensures a leading short circuit. Connected measuring transducers are therefore automatically protected against damage.
Current transformers
Current transformers are measuring transducers that convert an incoming electrical variable such as the amperage or the electrical voltage into a proportional, deviating output variable. They reduce large current voltages and strengths because these currents are often too high for conventional measuring devices. These variables must be reduced proportionally to make them measurable. This requires transformers. The energy industry is just one industry in which such transformers are used, and therefore transformer terminal blocks as well. The test-disconnect terminal blocks from Phoenix Contact enable you to set up your measuring transducers in compliance with the relevant technical and standard requirements. With fast switching options in the form of section disconnectors and switching bridges, the various measurements are made possible without significant effort.
