Contactor, Push Buttons & Switches

 

contactorContactor adalah sebuah alat listrik yang bekerja berdasarkan prinsip induksi elektromagnetik. Pada Contactor terdapat sebuah lilitan dimana bila dialiri arus listrik akan timbul medan magnet pada inti besinya, yang akan membuat kontaknya tertarik oleh gaya magnet yang timbul tadi. Kontak Bantu NO (Normally Open) akan menutup dan kontak Bantu NC (Normally Close) akan membuka.

 

Contactor terdiri dari kontak utama dan kontak Bantu. Kontak utama digunakan untuk rangkaian daya sedangkan kontak bantu digunakan untuk rangkaian kontrol.

Didalam sebuah kontaktor elektromagnetik terdapat kumparan utama pada inti besi. Kumparan hubung singkat berfungsi sebagai peredam getaran saat kedua inti besi saling melekat.

Apabila kumparan utama dialiri arus, maka akan timbul medan magnet pada inti besi yang akan menarik inti besi dari kumparan hubung singkat yang dikopel dengan kontak utama dan kontak Bantu dari kontaktor tersebut. Hal ini akan mengakibatkan kontak utama dan kontak bantunya akan bergerak dari posisi normal dimana kontak normally open akan tertutup sedangkan Normally Close akan terbuka. Selama kumparan utama kontaktor tersebut masih dialiri arus, maka kontak-kontaknya akan tetap pada posisi operasinya.

Apabila pada kumparan kontaktor diberi tegangan yang terlalu tinggi maka akan menyebabkan berkurangnya umur atau merusak kumparan kontaktor tersebut. Tetapi jika tegangan yang diberikan terlalu rendah maka akan menimbulkan tekanan antara kontak-kontak dari kontaktor menjadi berkurang. Hal ini menimbulkan bunga api pada permukaannya serta dapat merusak kontak-kontaknya. Besarnya toleransi tegangan untuk kumparan kontaktor adalah berkisar 85% - 110% dari tegangan kerja kontaktor.
