2.5.2 Connection
Tools
You require the following to connect the circuit breakers:
• Frame sizes S00 to S2: Pozidriv 2 screwdriver
• Frame size S3: Allen key (4 mm)
Conductor cross-sec-
tions
The typical SIRIUS conductor cross-sections apply (see Section 1.5.2 "Con-
ductor cross-sections").
Screw-type terminals
3RV1 circuit breakers with frame sizes S00 and S0 have terminals with cap-
tive screws and terminal washers that enable you to connect 2 conductors,
even if they have different cross-sections.
The box terminals of the circuit breakers of frame sizes S2 and S3 can also
take 2 conductors with different cross-sections. With the exception of circuit
breakers of frame size S3, which have terminal screws with a 4 mm Allen
screw, all the terminal screws can be tightened using a standard screwdriver
or a Pozidriv screwdriver (size 2).
You can remove the box terminals from circuit breakers with a frame size of
S3 to connect conductors with lugs or connecting bars. A terminal cover is
available as shock protection and to ensure that you comply with the
required creepages and clearances when the box terminals are removed.
Soldering pin connec-
tor
Circuit breakers in frame size S00 can be soldered onto printed circuit
boards by means of a soldering pin connector. A soldering pin connector is
available for the main contacts and the transverse auxiliary switch.
