1 IEC Technical Data DC Circuit Switching A/AE9 – GAE75
Acr oss the IEC Technical data contactors DC circuit switching line 1 A/AE9 – GAE75 1 General The arc switching on d.c. is more diffi cult than on a.c. • For selecting a contactor it is essential to determine the current, the voltage and the L/R time constant of the controlled load. • For information, typical time constant values are quoted hereafter: non inductive loads such as resistance furnaces (L/R ~ 1 ms), inductive loads such as shunt motors (L/R ~ 2 ms) or series motors (L/R ~ 7.5 ms). • The addition of a resistor in parallel with an inductive winding helps in the elimination of the arcs. • All the poles required for breaking must be connected in series between the load and the source polarity not linked to earth (or chassis). a.c. operated contactors A9 A12 A16 A26 A30 A40 A45 A50 A63 A75 GA75 a.c. / d.c. operated (electronic coil interface) – – – – – – AF45 AF50 AF63 AF75 – d.c. operated contactors AE9 AE12 AE16 AE26 AE30 AE40 AE45 AE50 AE63 AE75 GAE75 Utilization category DC-1, L/R < 1 ms ≤ 72 V A 25 27 30 45 55 60 70 100 110 120 120 110 V A 10 15 20 – – – – – – – 120 220 V A – – – – – – – – – – 120 440 V A – – – – – – – – – – 100 600 V A – – – – – – – – – – 75 ≤ 72 V A 25 27 30 45 55 60 70 100 110 120 – 110 V A 25 27 30 45 55 60 70 100 110 120 – 220 V A 10 15 20 – – – – – – – – ≤ 72 V A 25 27 30 45 55 60 70 100 110 120 – 110 V A 25 27 30 45 55 60 70 100 110 120 – 220 V A 25 27 30 45 55 60 70 100 110 120 – ≤ 72 V A 25 27 30 45 – – 70 100 – 120 – 110 V A 25 27 30 45 – – 70 100 – 120 – 220 V A 25 27 30 45 – – 70 100 – 120 – 440 -

I N S T A L L A T I O N I N S T R U C T I O N S R O T A R Y PHA S E C O N VE R T E R S Notice Before permanently installing this converter make sure it will operate your load! You may temporarily connect your converter through the cover opening and satisfy yourself that your converter is adequate to operate your equipment before removing any knockouts or making permanent connections which would prevent return or exchange of this device. Be sure to read all the instructions carefully before you attempt installation–we cannot be responsible for the failure of an incorrect installation. Important–To the installing Licensed Electrician 1. The generated phase (T3) is red in color. DO NOT connect the generated phase (T3) to any single-phase loads, lights, or magnetic starter holding coils. 2. DO NOT connect a single-phase supply line to T3 3. This is a Delta 3-phase system. High voltage to ground (neutral) from T3 is perfectly normal and will not affect the normal operation of 3-phase equipment. W arning: Disconnect power before servicing or connecting any equipment! Electric shock can injure or kill you. This equipment should be installed in accordance with local and National Electric Codes. 1. Connect your rotary converter(s) and 3-phase equipment according to the appropriate wiring diagram following. Charts are provided which list wire, transformer and fusing recommendations for converters and 3-phase motors. Be sure all equipment is properly grounded per NEC Article 250. -
