Keep your solid-state relay running cool with this heatsink from Sensata | Crydom. It's a handy multitasker that handles up to three single or dual SSRs, or a single three-phase SSR. Simply clip it onto a DIN rail or mount it on a panel for installation in a snap. The entire unit is made of aluminium and weighs just 544g, so it's strong yet light enough to place minimal strain on your assembly. You'll find it used in industrial automation and motor control applications.

• Accepts a 2-40mm fan for extra cooling
• Thermal resistance of 1°C/W ensures efficient heat transfer
• Black anodised finish for extra heat dissipation

All SSRs generate heat when they operate. Installing a heatsink is an efficient way to manage this heat so it doesn't damage the relay or interfere with its performance.

Relay heatsinks have a number of vertical fins. These fins provide a large surface area to cool the hot air created by the relay's operation. The heatsink needs to be positioned in a ventilated area so the cooled air can be expelled into the environment.
