FAQ

A600 and Q600 are NEMA (National Electrical Manufacturers Association) ratings for the contact capacity in AC and DC circuits, respectively. A600 indicates the relay can handle making/breaking 10A at 600V AC, while Q600 relates to its performance in DC circuits, ensuring it's suitable for a wide range of industrial control applications in North America.

Yes, the TeSys K series is modular. You can typically add front-mounting auxiliary contact blocks to expand the number of NO or NC contacts, providing greater flexibility for your control circuit design.

The module is likely a surge suppressor (e.g., LA4KE1FC), designed to clip onto the relay. It protects the control coil from voltage spikes, which can extend the life of the relay and protect sensitive control electronics like PLC outputs. It is recommended but not always mandatory for operation.
