Screw Clamp Terminals are the most extensively used component in the electrical sector when it comes to connection technology. Screw Clamp connections have a high level of popularity since they have shown to be the most reliable over decades, with billions of connections created and in use.
The typical Screw Clamp Terminal block can be divided into multiple ranges based on the features they provide are listed by Elmex Controls Pvt. Ltd. - one of the most prominent clamp manufacturers in India.
- Feed Through Terminal Block:
Instrumentation, Power Distribution, Control, as well as Automation applications benefit from one of the most adaptable terminals available. With the help of a screwdriver, a specifically designed flexible foot allows easy mounting and removal from the DIN rail. Marker retaining grooves on these Terminal Blocks accept marking tags for circuit identification. Screw-type jumpers can be used to create cross-connections.
- Multi Connection Terminal Block:
These Terminal Blocks are designed to solve reliability issues that arise when several wires must be connected in a single Terminal Block. Because of the numerous connection points provided in the terminal block, they are an excellent choice for future-proofing circuits.
- Multi-Level Terminal Block:
Double and triple-level Terminal Blocks are appropriate for high-density wiring applications. Triple-level Terminal Blocks are an excellent alternative for sensor and actuator applications in control systems. The circuit's wire density can be greatly increased thanks to the simplified 3-level connectors.
Grounding / Earthing wires are terminated with them. According to industry standards, they are colour coded green-yellow. These terminals are identical in form and thickness to the feedthrough terminals of the same wire size. Elmex Controls Pvt. Ltd. - one of the excellent terminal blocks with brass manufacturers offers a wide range of the best quality terminal blocks in India.
They protect you from the short circuits and assure that the system operates in a fail-safe manner. Inside the inbuilt fuse carrier that is hinged and captive in the Terminal block, these fuse terminal blocks may accept 5x20 mm glass cartridge fuses.
Fuse carriers having the "Blown Fuse" indicator feature are specially intended to help quickly discover issues.
Fuse & Feed on Multiple Levels For DCS applications, through terminals, allow two-wire sensor and actuator connections to be made in a single terminal block, improving wiring density and minimising control cabinet size.
- Disconnect Terminal Blocks:
They enable the disconnection of the electrical circuits in the system for testing reasons in a quick, simple, and safe manner.
Knife contacts that have been specially constructed can be manually opened or operated with a conventional screwdriver. For connecting Voltage transformer circuits and Current in the panels of switchgear protection, sliding link Disconnect & Test Terminal Blocks are available along with Screw Clamp Terminals. Disconnection of the circuit is accomplished by using a screwdriver to open the central sliding link.
Multiple Level Disconnect Terminals for DCS applications allow two-wire sensor as well as actuator connections to be made in a single terminal block, improving wiring density and minimising control cabinet size. In the Oil and Gas and Continuous Process sectors, our extremely safe disconnecting terminals are the ideal solution for hazardous site applications.
- High Voltage Terminal Blocks:
They were created specifically for applications requiring exceptionally high voltage. Clearance distances, as well as additional creepage, are built into the terminal as a result of its design to meet regulatory standards. They're especially well-suited to solar-related applications.
- Spring Loaded Terminal Block:
These Terminal Blocks are recommended for applications involving the SEC, NTPC safety, Electric Supply Industry (ESI) standards, as well as British CEGB regulation requirements. These blocks include a built-in spring-loading mechanism in addition to the high torque screws. For terminating wires in such connections, a hook type lug/ferrule is advised. These Screw Clamp Terminals contain a particularly constructed current bar for proper installation and location of wires crimped with hook type lugs, preventing wire loosening even when the screw clamps are not tightened.
- Modular Distribution Blocks:
They're a great option for streamlining your distribution system.
A bolt in the centre of the CDB series block serves as a connection point for the incoming cable. Internally, a single current bar connects all of the adjoining terminals, providing several connection sites for the outgoing wires. The incoming link is effectively shrouded by a protective shield.
The CMDB Terminal Blocks are a modified variant of the CDB Terminal Blocks that do not have a central incoming terminal connection and have the same wire size at input and output.
These Terminal Blocks are small and are utilised in applications where space is limited. Rails of the DIN 15 type should be used with these blocks.
- Panel Mount Terminal Block:
For particularly tiny wire applications, panel mount Terminal Blocks are a great alternative. These "modular"
Screw Clamp Terminals can be stacked to make multipole assemblies. An End Plate can be used to mount the stacked assemblies on the panel surface. Control Transformers, Elevators, Junction Boxes, and applications with restricted wiring space benefit greatly from these Terminal Blocks.
- Thermocouple Terminal Blocks:
They're employed in measurement applications with thermocouple wires. The current-carrying element of the Terminal Block is composed of the same material as the thermocouple wire, according to DIN 43713 and DIN 43714.
- Tab Connection Terminal Block:
With the use of "Fast On type" lugs, these Terminal Blocks provide a rapid connection. The connection is made by pressing the lug against the Terminal Blocks' tab blade.
- Component carrier Terminals:
They make it easier to put electronic components in plugs that have been specially designed. After that, the plugs can be attached to the base terminal. Without detaching the wires from the base terminals, the plugs can be simply replaced if they fail during operations.
- Terminal Blocks with Electronic component:
Certain circuits in industrial control panels are highly sensitive and also require extra safeguards. Electronic Component Terminal Blocks combine resistors, diodes, as well as LEDs with other electronic components. Elmex Controls Pvt. Ltd. manufactures world-class
Terminal Block with LED Indicator in India. They are useful in applications such as protection and in-circuit indication.
