Reliable Testing and Isolation for Current Transformer Circuits
Test disconnect terminal blocks such as the TE Connectivity M6/8.ST1.V2.IP20 are particularly useful in current transformer secondary circuits, where safe measurement, isolation and short-circuiting procedures are important during commissioning and maintenance. The screwdriver-operated sliding link provides a controlled method of disconnecting the circuit while leaving the field conductors securely terminated.
The two integrated 4 mm IP20 test sockets allow compatible measuring equipment to be connected directly to the terminal block, while PCS sliding short-circuiting bridges can be used for convenient short-circuit operations across groups of terminals. This combination makes the M6/8.ST1.V2.IP20 a practical solution for metering, protection, switchgear and industrial electrical measurement installations.
Typical Applications
- Current transformer secondary circuits.
- Electrical metering and measurement systems.
- Protection relay and monitoring circuits.
- Industrial switchgear and distribution panels.
- Control panel testing and commissioning.
- Automation, instrumentation and electrical maintenance systems.
