الأوفر لود ( Overload )

ويسمى قاطع الوقاية من زيادة الحمل ويركب مع بعض الضواغط فى أجهزة الشباك والإسبليت ويكون ملاصقاً لجسم الضاغط حيث أنه يكتسب حرارة من جسم الضاغط أثناء التشغيل العادى ويكون الفصل عند ارتفاع الأمبير أسرع مما يكون بعيداً عن جسم الضاغط .

- عند الفصل يأخذ زمن فصل أطول عندما يكون مركباً بمكانه وملاصقاً للضاغط وهذا يتيح فرصة تعادل الضغوط قبل توصيله مرة أخرى .

- يوصل OL بالتوالي مع طرف C للضاغط

الريلاى ( Relay )

# وظيفته خروج ملفات التقويم من الدائرة عندما يبلغ الضاغط حوالي %75 من سرعته
