The FHSI0150W white heat sink radiator is designed to accompany a 40A singlephase solid state relay (SSR). It provides a compact, purposebuilt cooling solution for SSR installations and is associated with the FHSS40 model within the product line. It features a white finish suitable for control panels and enclosures. Key benefits Enhances reliability by helping to dissipate heat from 40A singlephase SSRs, reducing thermal stress and potential performance loss. Compact footprint fits into tight control panels and enclosures without compromising space for other components. Clean white finish offers a neat, professional appearance in equipment housings. Simple, purposebuilt solution tailored for SSR heat management. Clear product alignment with the FHSS40 SSR heat sinking application, supporting maintainable and orderly panel design.

Size and dimensions: Dimensions listed as 80(60) x 50 x 50 mm; also specified as 80 60 50 mm. Color: White. Material: Material not specified in the listing. Model and series: FHSS40 heat sink radiator; product family includes FHSI0150W. Power reference: 50W appears in the product naming, indicating its configuration within the FHSI0150W line. Additional notes: The listing specifies a white 80(60)*50 * 50 mm footprint and 80 60 50 mm sizing, confirming the intended mounting footprint for SSR cooling. Two to three use cases Use case 1: In an industrial control panel, a 40A singlephase SSR driving a heating element or other resistive load benefits from the FHSS40 heat sink to maintain stable operating temperatures and protect SSR longevity. Use case 2: In an HVAC or climate control module, where a 40A SSR switches AC loads, the heat sink helps manage heat in a compact enclosure, supporting reliable operation. Use case 3: In laboratory testing or prototype setups using a 40A singlephase SSR, the FHSS40 heat sink provides a readymade cooling solution that simplifies thermal management during development. Notes Material composition is not specified in the listing; verify material details with the supplier if a specific metal or alloy is required for your application. The description reflects the product branding, model references, size specifications, and intended SSR compatibility as stated in the product title.
