Why Choose the Teknomega PTB3111 Power Terminal Block?
The Teknomega PTB3111 is a compact 1-pole, 2-way power terminal block designed for reliable conductor connections within industrial switchboards, electrical distribution panels and automation cabinets. Also referenced as PTB-1-35-G, it provides a secure 1 input / 1 output connection for copper or aluminium conductors up to 35 mm².
The PTB3111 combines a durable PA66 UL 94-V0 insulating body and cover with a tinned aluminium conductor block and galvanised steel screws. This construction provides dependable electrical contact and secure mechanical clamping while the self-extinguishing insulating material supports safe installation within industrial electrical enclosures.
With a rated insulation voltage of 1000 V AC / 1500 V DC, an impulse withstand voltage of 8 kV and IP20 protection, the PTB3111 is suited to demanding power distribution applications. Its compact grey housing measures approximately 47.4 × 16.3 × 40.3 mm, helping panel builders create organised high-current connections while conserving valuable enclosure space.
