The Kuangya KYSPD-20T2+3-2P is a surge protection device for electrical panel
designed for single-phase AC systems at 230 V. It combines Type 2 and Type 3 protection classes,
ensuring effective surge suppression in distribution boards and protecting sensitive loads
such as computers, appliances, and building electronics.

It uses MOV surge absorption with pluggable modules for easy maintenance, and integrates
a thermal disconnector with clear green/red status display. Optional RC contacts allow
fault signaling for integration with monitoring systems such as BMS or PLC.
