Auxiliary contact blocks for OT160EV…4000, IP20

Contact numbering according to EN 50013. Early break type auxiliary contacts means

that in the switches, the NO aux.contacts break before the main contacts open.

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

(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

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

place (see mounting instructions). In order to activate the "test" and "test indication" fea-

tures a handle with test function is required. The test contacts can be used as standard

auxiliary contacts as well.

See next pages for performance data, functions and contact timing.
