Frequently Asked Questions
Is this suitable for my 12A SSR (SSRP1DA012)?
Yes — the SSS1X is sized for 10-12A hockey-puck style SSRs, matching EMAS's SSRP1DA012 relay. For 25A or 40A relays, use the larger SSS2X instead.
Will this fit SSRs from other manufacturers?
Likely yes — it's a universal fitting designed for the common hockey-puck SSR form factor used across most brands, not just EMAS relays.
Do I need forced-air cooling for continuous-duty use?
Depends on ambient temperature and duty cycle — for standard use this passive heatsink is sufficient, but fan-assisted versions are available if you need extra cooling margin in hot environments or high-duty applications.
How is it mounted?
Rail mount, fitting DIN rail or chassis mounting in a standard control panel.
Industry Applications
- Process heating panels — thermal management for SSRs driving heating elements continuously
- Panel builders — universal-fit heatsink for retrofitting or building up custom SSR assemblies
- Plastics & packaging machinery — supporting high-cycle SSR switching without overheating
