Auxiliary contacts for OTM40...4000, IP20

Contact numbering according to EN 50013. Types _AU have gold plated contacts for harsh

environments and low operating voltages. Auxiliary contacts are mountable on right side in

types OTM40…4000 or under the mechanism cover in types OTM160…4000. 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 func-

tions are achieved when an auxiliary contact block is installed in a specific place.

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