Transformer terminal blocks with various connection technologies

Transformer terminal blocks for convenient test circuits

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.

Advantages

  • Maximum functionality with up to six universal function shafts for potential distribution or test purposes
  • Modular design for current transformer and measuring transducer switching with plug-in transducer terminal blocks
  • Reliable protection of connected current transformers and measuring transducers with plug versions with integrated leading short-circuit contact
  • Simple and functional design with feed-through terminal blocks and ground terminals of the same shape
  • Reliable contacting and latching of the section disconnector in the relevant switching state
  • Clear marking of the switching states

Current transformers and measuring transducers

The current transducer terminal blocks allow you to freely select the connection technology. A patented triple function shaft was used in the design of the current transducer terminal blocks. This is also one of the reasons why the compact design of the terminal blocks could be guaranteed. The section disconnectors on the terminal blocks allow safe switching 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 are available.

Automatic and safe short-circuiting

You can safely and conveniently short-circuit the measuring transducer 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 securely latched in place. In addition to the short-circuit bridge version, plug-in terminal block versions 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.
