Multispan CC-510 vs CC-520 — Which Cooling Controller?
The Multispan CC-510 and CC-520 are single-stage cooling controllers that differ only in compressor relay rating — 10 A vs 20 A. Here is how to choose, with a side-by-side spec table.
The Multispan CC-510 and CC-520 are single-stage refrigeration / cooling controllers from the Cryo CC series. They are functionally identical — NTC sensor, ON-OFF cooling with adjustable hysteresis and time-based defrost — and differ only in the compressor relay rating: the CC-510 switches 10 A and the CC-520 switches 20 A. Choose by the current your compressor or contactor coil draws.
Which to choose
Which should you choose?
Choose the CC-510 (10 A)
For small cold rooms, display cabinets and light-commercial refrigeration where the compressor or contactor coil is within 10 A.
Choose the CC-520 (20 A)
For larger condensing units and higher-current compressors up to 20 A, or where you want extra headroom on the switching relay.

FAQ
CC-510 vs CC-520
What is the difference between Multispan CC-510 and CC-520?
Both are single-stage NTC cooling controllers with the same control, defrost and display; the only difference is the compressor relay rating — 10 A on the CC-510 and 20 A on the CC-520. Pick by your compressor or contactor current.
Can the CC-520 replace a CC-510?
Yes — the CC-520 is a drop-in upgrade with a higher 20 A relay and will run any load a CC-510 handles. Confirm the panel wiring and supply voltage when swapping.
