Siemens 3TK2031-6AC2 contactor with 3NO+1NC contacts (ref. AGWSELE1278).
Miniature contactor of the Siemens 3TK20 series: three normally open power contacts (3NO) plus one normally closed auxiliary contact (1NC), driven by a 24 V AC coil. In the electrical panels of professional machines the contactor switches the load (motor or heating element) on command of the low-voltage auxiliary circuit: push buttons, thermostats or control boards drive the coil, and the contactor closes the power contacts.
When to replace it: machine not starting although the coil is powered, welded contacts that no longer open the load, loud coil humming, contactor running hot or chattering. The 3TK20 series is no longer in the Siemens catalogue, so this spare part is the direct way to repair existing equipment without rewiring the panel.
