[*1]The making and breaking current capacities apply to contact A of all models, and the electrical life to contact A for load switching.
[*2]Beware that contact B is capable of conducting only and not breaking.
[*3]The current and resistance values of the coil represent those at an ambient temperature of +20°C, and the tolerance on them is ±10%.
[*4]The minimum pickup voltage represents that at an ambient temperature of +60°C and hot coil start.

Notes:

[*1]Use 90 to 110 kg·cm as the tightening torque of the main circuit terminal (M8).
[*2]Connect the positive pole (+) to the terminal marked with the main circuit polarity marking P.
(The contactor structure is such that arc is led out front by built-in magnet.)
[*3]Install the DC contactor with the UP side up.
[*4]Provide a space of 10 mm or more between contactors when two or more
