Auxiliary contacts
Auxiliary contacts for OS 32G...1250
Mounting under the mechanism cover:
The “test” contacts operate in ON- and OFF-positions as well as when the handle is turned to TEST-po-
sition = 45 degrees over the OFF-position. The “test indication” contacts operate only when the handle
is turned to TEST-position. See the function table below. The OA1G10 (N.O.) or OA3G01 (N.C.) auxiliary
contact blocks can be used as standard auxiliary contacts, “test” or “test indication” contacts. The
desired functions are achieved when an auxiliary contact block is installed in a specifi c place shown in
the mounting instruction. In order to activate the “test” and “test indication” features a handle with test
function is required. See the optional handles, page 30.
Function table of OS32G…1250 auxiliary contacts
Maximum number of contact blocks, “Aux./test” contacts and “test indication” contacts, see the table
below. Standard versions include all except for N3-types which are equipped with integrated neutral
through the mechanism.
Maximum number of auxiliary contacts under the mechanism cover
The contact timing: see the chart, pages 63-64.
Mounting on the left side of the switch fuse:
Maximum 8 auxiliary contact blocks (N.O. or N.C.) with the OEA28 module. Units/type = 1 piece.
Types _AU have gold plated contacts for harsh environments and low operating voltages.
