The SSS4X gives a 40A hockey-puck-style solid state relay a proper heat sink to dissipate the heat it generates under load, mounting to DIN rail or chassis with a slimline profile that doesn’t eat excessive panel space. Without adequate heat sinking, an SSR at this current rating can overheat and fail prematurely this is sized specifically for the 40A class, including EMAS’s own SSRP1DA040 and the Novus 40A SSR (a separate brand we also stock).

EMAS heat sinks are a slimline design with versatile mounting to DIN rail or chassis. Universal fitting – works with the majority of hockey puck style Solid State Relays.

Solid build quality with 3 year warranty as standard.

Options are available with fans for assisted cooling.
