Product Description

Tavsif

Siemens 3RW4447-6BC45 uch fazali asinxron motorlarni boshqariladigan tarzda ishga tushirish va to‘xtatish uchun mo‘ljallangan SIRIUS 3RW44 yumshoq ishga tushirgichidir.

Qurilma 400–600 VAC asosiy zanjir kuchlanishida ishlaydi. 500 V va 40 °C da standart zanjir ko‘rsatkichlari 432 A va 315 kW ni tashkil etadi.

Delta ichidagi qo‘llanilishlarda ushbu qurilma 500 V va 40 °C da 748 A va 500 kW ni qo‘llab-quvvatlaydi.

3RW4447-6BC45 qurilmasi 230 VAC boshqaruv ta’minoti va vintli yordamchi hamda boshqaruv klemmalaridan foydalanadi. Uning asosiy tok zanjiri shina ulanishlaridan foydalanadi.

Yumshoq ishga tushirgichda integratsiyalangan bypass kontakt tizimi, motorni ortiqcha yuklanishdan himoyalash, qurilmaning ichki himoyasi, termistor orqali motorni himoyalashni baholash, sozlanadigan tokni cheklash va tashqi qayta tiklash imkoniyati mavjud.

Ushbu katalog raqami Siemens tomonidan ishlab chiqarishdan chiqarilgan. Afzal ko‘rilgan voris model — 3RW5547-6HA16.
