Note:
Logical separation: The terminals for the contacts and the
terminals for the coil are arranged on separate levels, e.g. above
for contacts and below for the coil. Logical separation is not
necessarily protective separation.
Protective separation: Protective separation prevents voltage of
one circuit affecting another circuit with sufficient protection
(IEC 61140).
