Contactor ac1 ac2 ac3 filter
These devices are dimensioned for different electrical loads and for different operating conditions. Another important consideration when selecting contactors is to ensure that the proposed cable conductor can be accommodated by the contactor terminals. More Information. The armature coil brings in high current in the initial position. Non- inductive or slightly inductive loads, example: resistive furnaces, heaters. Facebook Linkedin Linkedin Twitter.
AC duty (Alternating Current) for Contactors: AC Such duty contactors are used in resistive loads such as heaters and electrical furnace. Non-inductive or slightly inductive loads are included which means the power factor of the load lie between to 1. AC1 - These type of contactors are used for Non-inductive or slightly inductive loads they are used for Heaters which are resistive loads. AC3 – They are particularly used for Starting of squirrel-cage motors and switching off only after the motor is up to speed.
AC4 - Starting of.
On closing, the contactor makes the inrush current, which is about 5 On opening, the contactor breaks the rated full load current of the motor.
A few tips on how to select contactor for use in direct on line starter. Facebook Linkedin Linkedin Twitter.
This reduces as soon as the metal core enters the coil. Utilisation category. Any of the above may need special consideration and may necessitate the selection of a contactor of a higher AC3 rating than catalogued values would initially suggest.

AC4 — Starting of cage motors, plugging inching. The motor may have series of coils connected to either control the acceleration or even the resistance.
AC24V AC-2 h current I' and operational voltage U': AC-3 h z' = z (Ie/I') filters, output filters, grounding or shielding in the installation. Utilization category AC2 and AC3 - Switching of three-phase motors. range to up to xUs and reduces the rated current Ie/AC1 to the value of Ie/AC3 the use of e.g. input filters, output filters, grounding or shielding in the installation. The contact part of the contactor includes the power contacts as well as the auxiliary contacts. AC1 – Non-inductive rows; AC2 â€“ Contactors for starting of slip-ring motors; AC3 – Starting of squirrel-cage motors and Equipment Reviews (1); Events (3); Fan Circuits (1); Filter Circuits (16); Fire Alarm (3).
Any of the above may need special consideration and may necessitate the selection of a contactor of a higher AC3 rating than catalogued values would initially suggest.

A few tips on how to select contactors for use in direct on line starters. Within a utilization category, the suitable size may be selected for the respective type. Though their output is used for switching very high loads, they are controlled by a circuit with very less power.
Categories: Relays. For example, the switch-on and switch-off current at resistance load corresponds to the continuous operating current, while, for example, squirrel cage motors consumes multiple of the rated operating current during switch-on and in the acceleration phase.

|Contactors for DOL starters Contactors for use in direct on line starters DOL are normally selected by their AC3 ratingthat is the switching on of a cage type induction motor and switching off the supply to the motor after the motor has run up to full speed.
The characteristic of the load to be switched or controlled determines the requirements for the switchgear and its correct selection for the intended application. The following table provides an overview of the various abbreviations. Premium Membership. Previous post Next post. For their use in DC circuits, magnetic blowouts are also used. If the contactors are used to manage volts higher than volts, inert gases and also vacuum is used as frame housing.

In electrical engineering utilization categories are defined by IEC standards  and indicate the type of electrical load and duty cycle of the loads to ease selection of contactors and relays.
Within a utilization category, the suitable size may be selected for the respective type. Though their output is used for switching very high loads, they are controlled by a circuit with very less power.
