Teknomega PTB3411 heavy-duty single-pole grey power terminal block for aluminium and copper conductors from 35 to 150 mm², rated at 320 A for copper and 290 A for aluminium.
£10.50
The Teknomega PTB3411 is a heavy-duty single-pole power terminal block designed for secure termination of large aluminium and copper conductors inside industrial switchboards, electrical distribution panels and automation cabinets. Its compact two-conductor configuration provides a dependable connection point for high-current power circuits while helping maintain an organised panel layout.
Manufactured with a robust PA66 UL94-V0 self-extinguishing insulating body, a tinned aluminium conductor and galvanised steel clamping screws, the PTB3411 offers excellent conductivity, mechanical strength and resistance to corrosion. The terminal is supplied pre-greased, improving electrical contact and helping protect the connection against oxide formation without requiring additional grease on the cable.
Suitable for aluminium and copper conductors from 35 to 150 mm², the PTB3411 provides a continuous thermal current rating of 320 A for copper and 290 A for aluminium. Its grey housing is suitable for phase and general power circuit identification, while the versatile mounting design supports both 35 mm DIN rail and direct panel installation.
The Teknomega PTB3411 provides a secure and efficient method of terminating large power conductors within industrial electrical systems. Its high current capacity and strong clamping arrangement make it suitable for main feeders, incoming supplies and other demanding power distribution connections.
Compatibility with both aluminium and copper conductors helps simplify stock management and panel design. The pre-greased tinned aluminium conductor provides dependable long-term electrical contact, while the removable insulating cover and IP20 construction support safer installation inside protected electrical enclosures.
