It is designed to switch control signals and auxiliary loads in a motor starter or contactor assembly — the contacts follow the main contactor's coil state without any built-in delay. Rated 10 A at 24 V, it also handles 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — these are the thermal current ratings for the auxiliary circuit, not motor-load breaking capacity.
The size S00 footprint — 45 mm wide, 60 mm tall, 114 mm deep — fits the standard S00 slot in a Siemens motor starter assembly or on its own in a control panel.
Shock-rated at 10 g for 5 ms and 5 g for 10 ms — sufficient for most industrial machinery but not for extreme impact environments. Front protection is IP20 — finger-safe but not sealed against water ingress. Mount inside an enclosure rated for the environment.
