Product details
The Pentair 521034Z is the replacement surge board kit for the PC100 power center used with select IntelliChlor salt chlorine generators. It is the genuine Pentair part.
What the board does
The surge board sits between the incoming power and the chlorinator electronics and absorbs power surges and other electrical disturbances before they reach the control side. When it fails, the power center can stop driving the cell, and this board is the fix.
What is in the kit
The surge board, a surge suppressor and the wiring connectors needed to install it, so the swap does not depend on reusing old connectors.
Confirm that your system uses the PC100 power center before ordering.
