Spring Loaded Terminal Blocks

Unshaken Connections for an Uninterrupted Grid

≡ Spring Loaded Terminals

These terminal blocks are engineered for critical applications where safety and compliance are non-negotiable. Designed with a unique spring mechanism beneath the clamp, these terminal blocks offer enhanced reliability in line with ESI standards, British CEGB regulations, and requirements from utilities like SEC and NTPC.

With high-torque screws and a specially designed current bar, these blocks ensure secure placement of wires terminated with hook-type lugs or ferrules — even when the screw clamps aren’t fully tightened. This built-in spring loading feature provides a resilient, fail-safe connection, making them the preferred choice for high-integrity electrical installations.

Advantages

Specially designed current bar for wires crimped with hook type lugs

In compliance with ESI, CEGB, SEC, NTPC standards & regulations

Prevents loosening of the wires even when the screw clamps are not tightened

Built-in spring loaded feature in addition to screw clamp mechanism

Highlight

Spring Loaded - Disconnect & Test Terminal Blocks

CDS6U/SC

CDS6U/SC Screw Clamp Spring Loaded Disconnect & Test Terminal Blocks feature a sliding link mechanism for easy and reliable circuit disconnection. The sliding link includes a screw with an orange cap, which can be simply screwed or unscrewed to operate the circuit as needed. 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 links are available, ensuring smooth, safe, and efficient testing procedures. These terminal blocks are also available in various color variants, which are especially beneficial for quick and accurate phase identification.

Spring Loaded - Knife Disconnect Terminal Blocks

CKT4SPSC

These terminal blocks are suitable for connecting wires up to 4mm². Disconnection of circuit is achieved by lifting a lever which operates the knife contact, this feature helps user to easily disconnect the circuits without the need of removal of wire from the terminal block.

Spring Loaded Feedthrough Terminal Blocks

CTS4USC, CTS6USC, CTS10USC

These feedthrough terminal blocks feature a screw clamp system with spring loaded mechanism. Wire connection is achieved with the help of hook type lugs. Cross connection of terminal can be achieved with the help of standard screw type jumpers. The 4mm², 6mm² & 10mm² wire sizes terminal blocks shares the same profile hence needs a common end plate as an accessory.
