ASJ series residual current operated relay 1 Introduction ASJ series residual current operated relay can be combined with low voltage circuit breaker or low voltage contactor to form a residual current protection device, which is mainly used for the TT and TN system distribution lines with AC 50Hz and rated voltage of 690V and below. -
Page 6: Technical Parameters
A-type residual current measurement; Current percentage light column display; Rated residual operating current can be measured; ASJ20-LD1A Limit non-driving time can be set; Two sets of relay output (settable)note 1; With local and remote "test" and "reset" functions. Notes: 1. The function of setting for relay means that you can set the initialization and the output state of relay by yourself through the code dialing on the panel;... - Page 7 ASJ10 appearance dimensions ASJ10 installation dimensions The appearance and installation dimensions of ASJ10L-LD1A are shown in the figure below.

The ASJ cannot be adopted. If the PEN line is not grounded repeatedly, when the shell is charged, the incoming and outgoing current of the transformer is equal, and the ASJ is not TN-C activated. If the PEN line is repeatedly system grounded, part of the single-phase current will flow into the repeated grounding. - Page 14 Overall dimensions Hole size Installation dimensions Reference current (mm) (mm) (mm) Product model L-170*30 100~200 46*3 L-300*50 500~1000 70*4 49*5 L-350*50 500~1000 70*4 69*3 L-400*50 1000~1250 70*5 69*5 L-500*50 1500~2000 88*5 L-650*50 2000~3000 69*6 L-800*50 3000~5000 88*8 Φ Overall dimensions Hole size Installation dimensions Reference current...
