Релетата за наблюдение са тип реле, което изключва прекъсвача на веригата при откриване на повреда. Релето е електрически управляван ключ, който се използва за включване или изключване на захранването в дадена верига.
Релета за наблюдение са по-сложни от обикновените релета, тъй като имат регулируеми работни условия, докато нормалните релета превключват според фиксиран праг. Те изм...
