Connection methods
The 3RB20 and 3RB21 relays are available with screw terminals
(box terminals) or spring-type terminals on the auxiliary current
side; the same applies for the evaluation modules of the
3RB22/3RB23 relays.
The 3RU11 relays come with screw terminals.
Screw terminals (box terminals)
Spring-type terminals
These connections are indicated in the Technical
