The gures below show a 22.5 mm enclosure. The overall width, overall depth, terminals (type
and number of terminals) and accessories and mounted components are similar and may dier

11.2 General information
Special feature of the spring-type terminal:
Spring-type terminals are used for fast, vibration-proof wiring without the need for tools and
with cable routing and terminal operation from the same direction.
Replacement of terminals:
Individual terminals can be replaced not only in the case of screw-type connections, but also in
the case of spring-type connections (with push-in function). This process minimizes the wiring
overhead – only the individual terminal concerned needs to be rewired, not the entire device.
