Current Range: 25A – 125A

K3P Series Selection Check

Narrow the range by load voltage and current, then confirm control voltage, switching type, and document version.

56 models
Load condition Confirm AC / DC, single-phase / three-phase, load voltage, and maximum load current.
Control signal Match control voltage, control type, and zero-cross, random, or phase-control operation.
Thermal & accessories Review heatsink, fan, and safety cover needs by current, ambient temperature, and mounting style.
Document check Download the datasheet or send application details for KYOTTO model confirmation.
