Quick verdict
When a pool or spa salt chlorinator power center needs replacement, the main question is whether one 520556 unit offers a clearer fit or stronger reason to buy than the other. Here, the two 520556 Salt Chlorinator Power Center choices align on the points that matter most: each is a new, in-ground pool power-center replacement for IC20, IC40, and IC60 systems, and each is listed at USD 155.49.
Choose either 520556 Salt Chlorinator Power Center when the intended system uses one of those named IC models and a replacement power center is the goal. Neither choice has a stated advantage in price, model number, or compatibility.
At a glance
The comparison is especially even because the named model and intended use match across both choices.

Where each product wins
520556 Salt Chlorinator Power Center
This choice makes sense for a pool or spa automatic control system identified as IC20, IC40, or IC60. Its description positions it as a power center that supplies power and control communication for an electrolytic-cell setup, making it relevant when replacing that specific component rather than selecting a general pool accessory.
520556 Salt Chlorinator Power Center
The second 520556 Salt Chlorinator Power Center wins in precisely the same situation: an in-ground pool or spa setup using IC20, IC40, or IC60 equipment and needing the 520556 power-center replacement format. Its named model, new condition, and stated application mirror the other choice, so there is no feature-based reason to prefer one over the other.
Product notes
520556 Salt Chlorinator Power Center For Pool and Spa IC20 IC40 IC60
Pick this 520556 Salt Chlorinator Power Center for a replacement project centered on IC20, IC40, or IC60 pool and spa automatic control systems. The 520556 model and MPN are both named, while the description identifies the unit as a power center intended to work with electrolytic cells for chlorine-production systems. That gives shoppers a direct match point when the existing equipment calls for this particular component type. Installation directions are included, and the described process involves removing the previous power center, placing the replacement on a flat surface, and connecting power. The limitation is its focused stated fitment: it is presented for IC20, IC40, and IC60 systems, so it is best treated as a model-specific replacement choice.
520556 Salt Chlorinator Power Center For Pool and Spa IC20 IC40 IC60
This second 520556 Salt Chlorinator Power Center is equally suitable when the target is an in-ground pool or spa system using the named IC20, IC40, or IC60 models. It carries the same 520556 identifier and is described for the same power and control role within an electrolytic-cell chlorine system. For shoppers replacing a failed or removed power-center component in that defined setup, it provides the same straightforward match as the first choice. The product is also identified as new and classified as a power-center replacement, which keeps the selection focused on the intended repair category. Its practical limitation is also the same: the stated use centers on the three specified IC models, rather than serving as a broad, all-purpose pool control component.
Final choice by use case
For an IC20, IC40, or IC60 pool or spa automatic control system, either 520556 Salt Chlorinator Power Center is the appropriate pick based on the shared model number, power-center replacement type, and stated compatibility. Choose the first if it is the one already selected for your replacement plan; choose the second under the same conditions. With matching listed prices and matching core specifications, this is not a case where one choice offers a clearer use-case advantage over the other.
