توضیحات
ارستر های پر قدرت شرکت فونیکس کنتاکت با تکنولوژی منحصر به فرد برای حفاظت ثانویه تجهیزات وسیستم ها در برابر ازدیاد ناگهانی ولتاژ و جریان
Class B+C -T1+T2
قدرت قطع 100KA
Class B+C -T1+T2: اين ارستر بيشترين قدرت قطع را در بين ارسترهاي شركت فونيكس كنتاكت دارا مي باشد .در مواردي كه ارسترهاي كلاس B وC در يك شبكه نياز باشند؛ ميتوان از ارستر تركيبي به جاي آنها استفاده نمود كه باعث صرفه جويي در وقت و هزينه مي گردد.
