• AC/DC coil voltage specifications can now be more easily
distinguished thanks to the use of color-coded coil tape
and operation indicators (LED).
•
Latching levers convenient for circuit checking and MY(S) models
equipped with mechanical operation indicators and operation
indicators for monitoring operation status are available.
• Contact materials and contact structures can be selected
based on contact reliability and corrosion resistance.
*Voltage is printed on white tape in the case of the Standard 3-pole model (MY3).
