Phoenix Contact's newest terminal blocks use push-in technology (PIT) to reduce insertion forces by 50% compared with other spring-technology products. Available in a 2.5 mm2 cross section, PIT series accepts ferrules between 22 AWG and 14 AWG. The orange actuation button opens the spring to the maximum wiring space of 14 AWG. The universal button is compatible with any type of tool, even a pen.
