Phoenix Contact ST 2.5-QUATTRO Four-Wire Straight-Through Terminal Block

Product Positioning

ST 2,5-QUATTRO is a four-wire straight-through terminal block from the CLIPLINE series. A single terminal block provides four spring-clamp points, facilitating parallel wiring of multiple conductors at the same potential.

Core Product Advantages and Features

Four-hole parallel design

A single terminal block has four independent spring clamping points, which can be used to connect multiple wires with the same potential in parallel.

Spring clip connection

The screwless spring clip design allows for quick wiring and provides vibration resistance and anti-loosening properties.

High rated voltage and current

Rated voltage up to 800V and current up to 24A, suitable for power distribution circuits with high loads.

Standard DIN rail compatible

It can be installed on NS35/7.5 or NS35/15 rails and arranged on the same rail as other CLIPLINE terminals.
