• Recommended for SSR loads above 10A
  
• Multiple sizes available: 85g to 680g
  
• Easy installation with SSR modules
  
• Helps extend relay service life under continuous load
  
• Suitable for heating equipment and control cabinets
  
  

Q1: Why does an SSR need a heat sink?

A solid state relay generates heat during continuous load operation. A heat sink helps reduce operating temperature and improve relay reliability.

Q2: When should I use a heat sink for SSR?

A heat sink is recommended when the SSR load current is higher than 10A, especially for continuous heating control applications.

Q3: Can this heat sink be used for both single phase and three phase SSR?

Yes. Different sizes are available for single phase and three phase solid state relay modules.

Q4: How do I choose the right SSR heat sink?

Choose according to SSR current, load type, working time, installation space and ventilation conditions. Higher current or continuous load requires a larger heat sink.

Q5: Is thermal grease required?

For better heat transfer, thermal grease is recommended between the SSR base plate and the aluminum heat sink.
