3RT1016-1AB01

The Siemens SIRIUS 3RT1016-1AB01 is an S00 miniature contactor, belonging to the same 24V AC low-voltage control series as the 1AB02. The difference lies in its configuration with one set of normally open auxiliary contacts, suitable for operation indication or start interlock signals. The main circuit has an AC-3 rated capacity of 9A, 4kW at 400V, and a net weight of approximately 0.206kg.

Product Positioning

The 3RT1016-1AB01 and 1AB02 are both 24V AC coil contactors from the Siemens SIRIUS 3RT10 series. They feature a compact S00 frame, AC-3 rated 9A, and can switch 4kW three-phase motor loads at 400V, falling within the low-voltage safety control voltage range. The difference lies in the configuration of one normally open auxiliary contact, suitable for use as a running indicator or start-up interlock signal, making it a highly practical standard component in low-voltage control systems.
