1) only versions with 2xCO
2) only MSR
Same execution as MS220K,
additionally with electronic reclo-
sing lock. A switching is stored
until a RESET.

The MS220K is a particularly
economical standard design in
a 22,5 mm wide housing with
vertically arranged terminals.
Each terminal remains accessib-
le even if all others are already
occupied.
