Note

*1
The ratings of the 200V class in the parenthesis when frames 20 and 50 are provided with an enclosure.
*2
The rated thermal current applies to electromagnetic contactors.
*3
The pick-up and drop-out voltages apply to 200V 60Hz power source. In case of 50Hz, the figures for frame 8C - 125C are about 10% smaller and for frame 150C - 800C are about the same.
*4
Application of Category AC3 and AC2 to the reversible electromagnetic contactors and 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.
*5
The mark (●) in the application indicates that they are standard.
*6
Operating time is a reference value where 200V 50Hz is applied to AC200V coil. Operating time varies with coil voltage, frequency and phase so it is unsuitable for timing use.
*7
Testing conditions of electrical life (Category AC3) :
The making and breaking currents and operating frequency of the electrical life are tested as shown in the right drawing according to test conditions of JIS C8201-4-1, JEM 1038 and IEC60947-4-1.
*8
Themal overload relay for 220-240V 7.5kW is TR50B-1E.
*9
The minimum rating of auxiliary contact is 48V 10mA for the single contact and 24V 10mA for the twin contact.
