More information
Using this mounting concept, all additional 5ST3 components
can be combined with miniature circuit breakers of the 5SY and
5
SP4 series (no RC unit on 5SY5 universal current MCB).
The 5SY6 0.. miniature circuit breakers are only designed for the
mounting of auxiliary switches, fault signal contacts and remote
controlled mechanisms. The chart shows which additional
components can be mounted on either the right or the left.
