This manual describes the RDR6 series double‑metal‑plate thermal overload relays, which protect AC circuits and motors from overload, phase loss, and excessive start or stall times. It covers the applicable voltage range (up to 660 V AC), current ratings, environmental limits, and wiring diagrams.
Installation requirements, adjustment ranges, reset times, and ordering information are detailed, along with tables of compatible contactor models and recommended fuses. The document also lists the physical dimensions for the various RDR6 variants. This manual is written in Chinese.
