AUSILIARY CONTACT BLOCK 1NC S00/S0 is an accessory for contactors in the Siemens SIRIUS range, designed to add 1 normally closed (1NC) auxiliary contact to contactors or auxiliary contactors of size S00/S0. It is used to extend control and signaling functions in switchboards, such as for interlocks, status feedback, consents or safety stops in the control circuit. Siemens auxiliary blocks for these sizes are designed as modular components for 3RT2 / 3RH2 contactors and are available in front or side versions depending on the exact code.
