RDJ2 (LR2) series bimetallic type thermal over-load relay is suitable for the circuit of AC50Hz/60Hz, rated operating voltage Ue:660V, rated current 0.10~630 (A), as the use of over-load, break phase and protection of motor and circuit. The structure and main technique performance index of this thermal relay is the same with LR2 series thermal relay, therefore, LR2 series thermal relay can be entirely replaced by RDJ2 series thermal relay.
