Auxiliary contact blocks for OT160EV…4000, IP20
Contact numbering according to EN 50013. Early break type auxiliary contacts means 02
that in the switches, the NO aux.contacts break before the main contacts open.

03
In types with auxiliary contacts mountable under the mechanism cover, the "test" contacts
operate in ON- and OFF-positions as well as when the handle is turned to TEST-position
OA1G10, OA3G01 04
(45° over the OFF-position). The "test indication" contacts operate only when the handle
is turned to TEST-position. The OA1G10 (N.O.) or OA3G01 (N.C.) auxiliary contact blocks
13 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 specific
1 no
place (see mounting instructions). In order to activate the "test" and "test indication" fea-
14
tures a handle with test function is required. The test contacts can be used as standard
1NO auxiliary contacts as well.
