Overview
Standard two-tier terminals
With the two voltage levels routed through two separate tiers, the
two-tier terminals require 50 % less space than equivalent sin-
gle-tier terminals. To implement a wide range of switching tasks,
connecting combs can be fitted to both tiers of the spring-
loaded terminal series. Facilities for inscription are provided at
each clamping point.
PE/ground conductor function
Perfect mechanical and electrical contact with the support rail is
assured by simply snapping the terminals onto the rail.
The PE two-tier terminals meet all the requirements of
IEC 60947-7-2:
• Low contact resistance
• Non-corroding clamping points
• Green-yellow enclosure
• Additional inscription options
PE/L and PE/N types
The PE/L and PE/N types provide a PE/ground contact to the
support rail in the lower tier. The upper tier is designed as a
through-type tier. Color coding of the PE and neutral tiers en-
ables clear and unambiguous distribution of the potential.
