Partex TBPOLY3BLK black 3 A electrical terminal block strips supplied in a pack of 100 for joining and terminating compatible conductors in suitable low-current electrical wiring and equipment assemblies.
£46.25
The Partex TBPOLY3BLK terminal block is a practical electrical connection component designed for joining and terminating conductors in suitable low-current wiring applications. Featuring a 3 A current rating and a black finish, this terminal block strip provides a convenient solution for electrical installers, maintenance engineers and equipment manufacturers who require organised, accessible wire connections.
Supplied in a bulk pack of 100 terminal block strips, the Partex TBPOLY3BLK is particularly suitable for workshops, electrical installation projects and production environments where multiple connections need to be prepared. Terminal block strips help bring conductors together at defined connection points, supporting orderly wiring and making individual connections easier to locate during inspection, maintenance and modification.
The 3 A rated terminal block is intended for circuits where the operating current, conductor size and installation conditions fall within the product's specified limits. Its black appearance provides a consistent finish for compatible electrical assemblies. Whether used for equipment wiring, control circuits or general electrical connection work, the TBPOLY3BLK offers a straightforward approach to conductor termination when installed in accordance with the manufacturer's specifications.
The Partex TBPOLY3BLK black terminal block provides a convenient way to organise conductor connections in electrical assemblies. Terminal block strips are commonly used where individual wires need to be joined at accessible connection points rather than through permanent or improvised joints. This approach can simplify installation and help maintenance personnel identify connection locations during equipment inspection or fault-finding.
With a specified 3 A current rating, the TBPOLY3BLK is intended for appropriately rated low-current circuits. Before installation, the electrical designer or installer should verify that the expected continuous current, voltage, conductor size and environmental conditions are compatible with the terminal block. The current rating must not be exceeded, and any additional derating requirements should be considered where applicable.
The black terminal block strip can be incorporated into compatible equipment wiring arrangements where a consistent appearance is preferred. For installations containing multiple circuits, terminal connections should be identified using suitable marking methods and the applicable wiring documentation. Colour alone should not be used to establish conductor function, polarity or electrical safety status.
The pack of 100 strips makes the TBPOLY3BLK suitable for repeated installation tasks, equipment assembly and maintenance stock. Electrical contractors and manufacturing workshops can keep multiple terminal strips available for scheduled projects and replacement work. This bulk quantity is particularly convenient where similar connection arrangements are used across multiple pieces of equipment.
Correct conductor preparation is important for reliable terminal connections. Installers should follow the manufacturer's instructions for stripping length, conductor type, conductor size and termination method. Where screw-type terminals are specified, the recommended tightening torque should be observed; other connection mechanisms must be installed according to their own instructions. Conductors should be securely retained without damage to the conductor or insulation.
Terminal blocks should always be installed in an arrangement that provides the required protection against accidental contact, short circuits, mechanical strain and environmental exposure. The Partex TBPOLY3BLK should not be assumed to have a particular voltage rating, insulation class, flame rating or regulatory certification without confirmation from the manufacturer's documentation. Its suitability must be assessed as part of the complete electrical installation.

The Partex TBPOLY3BLK is used to join and terminate compatible electrical conductors in suitable low-current wiring applications. It can be used in equipment assemblies, electrical installations and maintenance projects where the circuit requirements fall within the terminal block's ratings.
The Partex TBPOLY3BLK has a specified current rating of 3 A. The operating current must remain within the manufacturer's stated limits, taking account of installation conditions and any applicable derating requirements.
Each pack contains 100 Partex TBPOLY3BLK terminal block strips, making it convenient for bulk electrical installation, workshop assembly and maintenance stock.
The TBPOLY3BLK has a black finish. Its colour provides a consistent appearance for electrical assemblies but should not be used as the sole method of identifying circuit function or electrical safety status.
The permitted conductor sizes should be checked against the manufacturer's technical specifications for the TBPOLY3BLK. Compatibility depends on the terminal design, conductor construction and approved cross-sectional area.
The product is identified by a 3 A current rating, but its voltage rating has not been specified here. The maximum permitted operating voltage should be confirmed from the manufacturer's technical data before installation.
The TBPOLY3BLK may be suitable for low-current connections within electrical control panels where its current rating, voltage rating, conductor compatibility and installation requirements are appropriate. Suitability should be verified against the complete panel design.
The number of connection positions per strip should be confirmed against the manufacturer's product specification. The stated pack quantity of 100 strips refers to the number of terminal block strips supplied, not the total number of individual connection positions.
Suitability for mains electrical wiring depends on the manufacturer's confirmed voltage rating, conductor compatibility, insulation properties and applicable installation standards. The 3 A rating alone is not sufficient to establish whether the terminal block is suitable for a particular mains circuit.
Whether individual strips can be divided depends on their construction and the manufacturer's instructions. Do not cut or modify the TBPOLY3BLK unless the product is specifically designed and approved for that purpose.
Installation should be carried out with the circuit safely isolated and in accordance with the manufacturer's instructions. The correct conductor size, preparation method, termination procedure and any specified tightening requirements must be followed. The completed connection should be appropriately enclosed and protected.
The 100-strip pack provides a convenient supply for projects involving multiple electrical connections. It is useful for equipment manufacturers, electrical contractors and maintenance teams who regularly require compatible terminal block strips.
Partex terminal block products provide practical connection solutions for electrical installation, equipment assembly and maintenance work. With its 3 A current rating, black finish and convenient pack of 100 strips, the TBPOLY3BLK supports organised conductor termination and accessible wiring arrangements when selected and installed in accordance with the manufacturer's electrical specifications.
