Um relé de corrente é um tipo de interruptor eletromagnético usado como parte dos sistemas de controle de equipamentos elétricos. Esses relés são comumente usados como sensores (relés sensores/de monitoramento de corrente) para monitorar o fluxo de corrente em equipamentos industriais e outros equipamentos sensíveis à segurança. Tais equipamentos utilizam relés de corrente para evitar mau funcionamento devido a quantidades excessivas ou insuficientes de corrente elétrica ("sobrecorrente" e "subcorrente", respectivamente).
Se uma corrente excessiva fluir por uma máquina equipada com um relé de corrente, o relé será ativado, desligando ou alterando a quantidade de energia que pode fluir pelo circuito ou circuitos aos quais o relé está conectado. Isso reduz a quantidade de corrente que pode circular pelo sistema. A mesma funcionalidade pode ser aplicada a máquinas ou outros equipamentos elétricos para evitar danos causados por subcorrente.
Os relés de corrente podem ser usados tanto em sistemas CA quanto CC, e sua capacidade de prevenir falhas de equipamentos devido a sobrecorrente e subcorrente os torna uma ferramenta eficaz de controle de riscos em locais de trabalho onde uma falha no equipamento pode causar ferimentos.
