Teknomega PTB3513 yellow-green single-pole power terminal block for aluminium and copper conductors up to 240 mm², rated for 1000 V AC or 1500 V DC electrical distribution applications.
£17.23
The Teknomega PTB3513 is a robust single-pole power terminal block designed for reliable connection of large aluminium and copper conductors in electrical distribution systems. Also identified by the reference PTB-1-240-Y, this yellow-green terminal provides a secure and efficient connection point for protective conductors in industrial switchboards, control panels and power distribution assemblies.
The terminal features a conductive body manufactured from tinned aluminium, allowing compatible aluminium and copper cables to be connected without requiring separate interface components. Its pre-greased terminal chamber helps improve electrical conductivity while protecting the connection against oxidation, simplifying cable preparation and installation.
Supporting conductors up to 240 mm², the PTB3513 is suitable for high-capacity electrical installations requiring dependable power or protective conductor termination. It has a rated insulation voltage of 1000 V AC or 1500 V DC, an impulse withstand voltage of 8 kV and a maximum continuous operating temperature of +85 °C.
Power terminals such as the Teknomega PTB3513 provide a secure interface between large conductors and electrical distribution equipment. The tinned aluminium conductive body enables effective termination of both aluminium and copper cables, helping panel builders reduce the number of additional connection components required inside an enclosure.
The terminal is supplied with conductive grease already present inside the connection chamber. This helps maintain electrical performance and protects aluminium conductors against oxide formation. Its high-dielectric insulating enclosure, durable fasteners and clearly identifiable yellow-green finish make it particularly suitable for protective conductor and equipotential bonding installations.
