The price varies significantly based on the Rated Operational Current (Ie), typically ranging from 9A to 2650A for the TeSys series. You must specify the Coil Voltage (AC or DC) and frequency (e.g., 24V, 110V, 230V), as DC coils or wide-range electronic coils (TeSys Green) are generally more expensive. Additionally, the Utilization Category (AC-1 for resistive loads vs. AC-3 for motor loads) and the number of Auxiliary Contacts (NO/NC) integrated into the unit will directly influence the final quote.
