O Dispositivo Diferencial Residual, ou DR, é um dispositivo de segurança utilizado em instalações elétricas. Sua função é detectar pequenas fugas de corrente em circuitos elétricos, acionando o desligamento imediato da alimentação e evitando que ocorram acidentes. Essas fugas podem acontecer por diferentes razões: um toque acidental, um fio desencapado, o uso de equipamentos elétricos em áreas molhadas ou até mesmo um brinquedo que foi inserido na tomada por uma criança. #dicasdeseguranca
