K8DT-AW 1-phase Overcurrent/Undercurrent Relay Datasheet

Relé monofásico de sobrecorriente/corriente mínima

Detección de errores en motores y otros equipos a través de los cambios de corriente. Monitorización de sobrecorrientes y corrientes mínimas simultáneamente con un mismo dispositivo.

Monitorización de corrientes de c.a. o c.c. con un mismo dispositivo
Se utiliza con CT disponibles en el mercado (lado secundario del CT: 0 a 1 A o 0 a 5 A)
Ancho de 17,5 mm para reducir el espacio necesario en los cuadros
Tecnología “push-in plus” que reduce el tiempo y esfuerzo de cableado
Homologación UL para aplicaciones en América del Norte
Doble orificio de inserción para conexionado múltiple (todos los terminales)
Modelos añadidos con salidas a transistor para una fiabilidad de contacto superior
Cumplimiento con RoHS
