Product Code

Terminal Model

PT4 - Push-in terminal with 4mm² nominal cross-section

Connections

TWIN - Three connections on one level
Blank - Standard two-connection version; omit TWIN and its preceding hyphen

Function

PE - Required protective-earth version; one shared earth potential, green-yellow housing

Description

Push-in protective-earth terminals

PT4-PE has two push-in connections; PT4-TWIN-PE has three. Each model uses one level and a shared metal conductor bonded to the grounding foot, providing one protective-earth potential. Both mount on NS35/7.5 DIN rail and have green-yellow housings with orange actuators.
