  • 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

  • Introduction Types of Motor Starters
    Introduction Motor starters are one of the major inventions for motor control applications. As the name suggests, a starter is an electrical device which controls the electrical power for starting a motor. These electrical devices are also used for the purpose of stopping, reversing and protecting electric motors. The following are the two major components of a starter: 1. Contactor: The main function of the contactor is to control the electric current to the motor. A contactor can make or break power to the circuit. 2. Overload Relay: Overheating and drawing too much current can cause the motor to burn out and become practically useless. Overload relays prevent this from happening and protect the motor from any potential danger. A starter is an assembly of these two components, which allows it to turn on or off an electric motor or motor controlled electrical equipment. The starter also provides the necessary overload protection to the circuit. Types of Motor Starters There are several types of motor starters. However, the two most basic types of these electrical devices are: 1. Manual Starters Manual starters are devices that are operated manually. These starters are extremely easy and straightforward to operate and do not require expert intervention. The starter includes a button (or rotary knob) which enables a user to turn the connected equipment on or off. The buttons feature mechanical linkages, which make the contacts open or close, starting or stopping the motor. The following features of a manual starter make it a preferred choice over other types: • These starters deliver a safe, as well as economical operation.

  • Introduction Contactor Components
    Introduction A contactor is an electrical device which is used for switching an electrical circuit on or off. It is considered to be a special type of relay. However, the basic difference between the relay and contactor is that the contactor is used in applications with higher current carrying capacity, whereas the relay is used for lower current applications. Contactors can be field mounted easily and are compact in size. Generally, these electrical devices feature multiple contacts. These contacts are in most cases normally open and provide operating power to the load when the contactor coil is energized. Contactors are most commonly used for controlling electric motors. There are various types of contactors, and each type has its own set of features, capabilities, and applications. Contactors can break current over a wide range of currents, from a few amperes to thousands of amperes, and voltages from 24 VDC to thousands of volts. In addition, these electrical devices come in varying sizes, from hand-held dimensions to sizes measuring a meter or yard on one side (approximately). The most common application area of the contactor is high-current load. Contactors are known for their capability to handle currents of over 5000 amperes and high power over 100 kW. Heavy motor currents produce arcs when being interrupted. These arcs can be reduced and controlled using a contactor. Contactor Components The following three are crucial components of the contactor: 1. Coil or Electromagnet: This is the most crucial component of a contactor. The driving force that is required to close the contacts is provided by the coil or electromagnet of the contactor.
