User Guide:
The Magnecraft SSR should be firmly mounted on a clean, smooth heat sink surface using thermally conductive or
suitable thermal transfer pads.
Heat Sink/Class 6 SSR Relay
Thermal management is a fundamental consideration in the design and use of Solid State Relays (SSRs) because of the
contact dissipation (typically 1 W per amp). It is, therefore, vital that sufficient heat sinking is provided, or the life and
switching reliability of the SSR will be compromised. The unique design of the Magnecraft aluminum heat sink maximizes
heat dissipation. This heat sink is available for Magnecraft’s panel mount SSRs and ensures reliable operation when
properly selected for the specific application. For ease of installation, all mounting holes are pre-drilled and tapped.
• The Magnecraft heat sink matches heat dissipation requirements for Magnecraft 6 Series SSRs; up to 50 amps.
• The Magnecraft heat sink design achieves outstanding thermal efficiency.
• The Magnecraft heat sink is pre-drilled and tapped to suit the Magnecraft SSR 6 Series “hockey puck style” range.
