Disconnect & Test Terminal Blocks

Designed for safe & error free Test Operations

✔ Easy Operation ✔ Safe Isolation ✔ Reliable Testing

Disconnect & Test Terminal Blocks are purpose-built to provide safe circuit isolation and reliable testing without the need to remove existing wiring, ensuring smooth operation and minimal downtime. Based on the application requirement & disconnect mechanism, you can choose the right terminal block to ensure both safety and efficiency.

Knife Type Disconnect Terminal Blocks, feature an integrated knife-type disconnect tab, which can be easily opened or closed using a standard screwdriver.

Sliding Type Disconnect & Test Terminal Blocks are specially designed for Current Transformer (CT) and Potential Transformer (PT) applications, offering a safe and efficient solution for measuring control and regulatory circuits. These terminal blocks feature an integrated sliding disconnect mechanism, enabling step-by-step isolation of current transformers with the aid of various compatible accessories such as jumpers and test plugs.

Advantages

Disconnect status identification with Orange coloured disconnecting element

Colour coded Test Plugs for testing operations

2, 3, 4 Pole sliding type jumpers for CT shorting

Lockout Caps for preventing accidental opening of circuits

Suitable for 3-Phase, 3-Wire & 3-Phase, 4-Wire transformer circuits

Highlight

Knife Type Disconnect Terminal Blocks

CPK Series Terminal Blocks

CPK2.5/4 multi-connection terminal block with Push-In technology, has 4 wire connection points with knife disconnect function. This helps user to easily disconnect the circuits without the need of removal of wire from the terminal block. Each connection point can accommodate 2.5mm² wires. Additional test points are available on the top for ease of testing and measurements.

Disconnecting Terminals for CT & PT applications

CDS6U series Terminal Blocks

CDS6U series Disconnect & Test Terminal Blocks for 6mm² wires, feature a central sliding link mechanism with an orange indicator, for easy and reliable circuit disconnection. These terminal blocks are specially designed and engineered for current transformer (CT) applications, making them ideal for meter testing & calibration tasks. To support testing operations, a range of additional accessories such as test plugs and CT shorting jumpers are available. These terminal blocks are also available in various color variants, which are especially beneficial for quick and accurate phase identification.

STH4DT series Disconnect & Test Terminal Block

STH4DT terminal blocks are ideal for CT & PT applications using ring-type lugs. The connection is established by placing the lug onto the stud, and then securely tightening the captive bolt within the hinge using a standard screwdriver, ensuring a firm and reliable connection. Also available in various colour variants which are beneficial when it comes to phase identifications.

CBDT4UNS series Terminal for CT Applications

CBDT4UNS is a 6mm² barrier-type, compact disconnect & test terminal block designed for reliable and efficient wiring in CT applications. Long studs allow for secure connections using wires with ring-type lugs. The studs can be easily opened with a screwdriver and are also compatible with banana plugs, enabling quick shorting of CT circuits during testing. Additionally, protective covers are available as optional accessories, designed to fit perfectly onto the terminal block, providing finger-safe protection and preventing accidental contact with live terminals

Disconnecting Terminal assemblies

CWSTHCT6 - Ready to use assembly for transformer circuits

CWSTHCT6 is a bolt type terminal block assembly, comprising of six terminal blocks stacked together and secured using end blocks. A pre-assembled jumper is integrated into the assembly and fastened with additional screws. CTs can be shorted by installing the provided shorting screws in the appropriate terminals.

Double Level Knife disconnect Terminal Blocks

CYDLK Series

CYDLK4 series are double-level knife disconnect terminal blocks, designed for efficient circuit isolation and connectivity. Featuring a knife disconnect mechanism on the top level and a feedthrough function on the bottom level, these terminal blocks provide versatile wiring solutions. The CYDLK4 series shares the same profile as the CYDLF series double-level fuse and feed-through variants, ensuring seamless integration and uniform panel design.

Double Level Disconnect Terminal Block

CPDLK2.5 is a double-level knife disconnect terminal block, featuring a disconnect function for both levels. Each level, top and bottom, can be independently disconnected, providing flexibility and ease during circuit isolation. For error-free operation, both levels are clearly color-coded, with distinct colored push buttons and knife tabs to ensure quick identification and safe handling.
