The pick-up and drop-out voltage apply to 200V, 60Hz power source. In case of 50Hz, the figures for frame 8C-125C are about 10% smaller and figures for frame 150C-600C are about the same.

Note

*1
Application of Category AC3 and AC2 to the reversible electromagnetic starters shall be limited to regular reversible operation in which a motor starts reverse rotation after it has once stopped. Category AC4 is applicable when the motor starts reverse rotation before it has completely stops. And the contactors used for reversible operation, they must be electrically interlocked using by mutual NC auxiliary contacts.
*2
Since Operating time depends on coil voltage, frequency or phase etc. the starters must not be applied for timing use.
*3
* : Thermal overload relay for 220 - 240V 7.5kW is TR50B-2E.
