Notes 1) The values 150, 300 and 600 indicate die maximum voltage for which an auxiliary contact can be used.
2) “Heavy Pilot Duty“ = High switching duty
3) “Standard Pilot Duty” = normal switching duty
4) Rating data for 3-phase contactors, for single-speed motors, without inching, reversing or regenerative braking.
