Phoenix Contact PT 1,5/S BU Protective Conductor Terminal Block, Push-in, 1.5 mm², Green-Yellow

In industrial control panels and building installations, electricians rely on the Phoenix Contact PT 1,5/S BU protective conductor terminal block to establish safe, maintenance-free ground connections. This green-yellow terminal block features push-in connection technology, allowing solid or flexible conductors from 0.14 to 1.5 mm² to be inserted directly without tools. The block mounts on standard DIN rails (NS 35/7.5 or NS 35/15) and provides two connection points for daisy-chaining protective earth conductors. Its compact single-level design saves space in dense terminal strips, while the polyamide housing meets UL 94 V0 flammability requirements and withstands operating temperatures from -60 °C to 105 °C.

Why choose it

The push-in connection system reduces wiring time by up to 50% compared to screw terminals, as solid conductors simply push into the clamping point without any tool. The green-yellow colour coding clearly identifies the terminal as a protective earth connection, preventing wiring errors. The compact design and compatibility with standard DIN rails make it easy to integrate into existing terminal strips, while the robust polyamide housing ensures long-term reliability even in harsh industrial environments.

Ideal use cases

• Grounding protective conductors in industrial control cabinets
• Building installation distribution boards
• Machine building and panel wiring
• Railway and transportation systems
• Any application requiring a compact, tool-free PE terminal block

Good to know
