Medium and high current (>5A) SSRs can generate a lot of heat during operation. Failure to manage the generation of heat by the SSR during switching may damage the SSR and lead to early failure. When using an SSR this problem of heat dissipation must be managed. It is very important to select an adequate heatsink if you plan on using your SSR at its maximum specifications. To help with heat dissipation, a thermal pad (packaged with all "hockey puck" type SSRs we sell) should be used between the relay and the heatsink. For very high performance applications, air cooling may also be necessary.

This heatsink is designed to slide onto standard 35mm O-type DIN rail.

Features

  • Recommended for relays switching loads of up to 20A
  • Mounting holes match standard "Hockey Puck" style SSRs
  • Mounting screws included

Relays

The mounting holes on this heatsink are designed to match the mounting holes on a standard "Hockey Puck" style relay. The screws needed to attach the relay are included with the heatsink. Here's a list of relays we sell that can fit onto this heatsink:
