This solid-state contactor was extracted from an operational industrial system during equipment upgrade. The SIRIUS 3RF2 series uses semiconductor switching technology for silent, contactless operation with long service life and no mechanical wear. Ideal for switching resistive and inductive loads in automation systems, motor control circuits, heating elements, and industrial machinery requiring reliable AC load switching with DC control signals. The built-in circuit breaker protection adds safety for short-circuit conditions.
