If you want to use circuit breaker as SPD maintenance switch, insert a wiring MCCB for DC on SPD power side (diagram below).

Even when the output current of solar cell array is low, use 20 AT or more for wiring MCCB.

Wiring MCCB

*1. When the wiring distance is longer than 10 m between the power conditioner and the surge protector in the switch gear, install near the power

conditioner.

*2. Cable length between the branch point and the earthing: 0.5 m or less recommended

*3. When the solar panel manufacturer requires earthing at negative line of DC side, do NOT use the earth terminal of the SPD but use the

L- terminal. If also, earthing at positive line is necessary, earth the L+ terminal.
