Overview
The terminal connection compartment, on the tension spring
side as well as the screw side, enables connection to a nominal
cross-section of 2.5 mm² or 4 mm², with or without end sleeves.
The advantages of the different connection types result from the
fact that the spring-loaded terminal of the hybrid through-type
terminal is used inside the control cabinet and the universal
screw connection is used at the end user's side. A PE terminal
with the same contour is available for the three-conductor termi-
nal. Contact is made by simply snapping the terminal onto the
support rail. This meets the requirements of IEC 60947-7-2:
• Low contact resistance
• Non-corroding clamping points
• Green-yellow enclosure
• Additional inscription options
