£4.45
The Teknomega PTB3023 is a compact and reliable single-pole power terminal block designed for distributing electrical power safely and efficiently inside switchboards, control panels and industrial electrical enclosures. Part of the Teknomega power terminal range, it supports both aluminium and copper conductors, making it a versatile solution for professional panel-building applications.
The PTB3023 features a tinned aluminium conductor body that enables dependable connections between aluminium and copper cables without requiring additional interface components. Its pre-greased terminals help improve electrical conductivity and protect the conductor contact area against oxidation, simplifying installation and long-term maintenance.
Designed for conductors from 1.5 to 16 mm², the PTB3023 provides a continuous thermal current rating of 85 A. Its yellow-green housing makes it particularly suitable for protective conductor and earthing distribution applications, while the compact 35 mm DIN rail mounting format allows straightforward installation inside modern electrical panels.
Power terminal blocks such as the Teknomega PTB3023 provide a secure and organised method of connecting and distributing conductors inside electrical control panels. The single-pole design allows multiple conductors to share a common electrical connection while keeping panel wiring compact, accessible and easy to inspect.
The PTB3023 is suitable for copper and aluminium cables, reducing the need for separate terminal types within the same installation. Its tinned aluminium conductor, pre-applied contact grease and robust screw connections help deliver consistent electrical performance in industrial power distribution and control applications.
