Aluminum heatsink for 1-phase SSR semiconductor relays. It is mandatory when the relay operates in upper range of its rated current as temperatures over 80C will damage the relay. The heat sink can be used for all 10-40A relays, providing them with better cooling and durability. The radiator can be mounted on a flat surface (prepared holes). Technical parameters: material: aluminum relay mounting hole size: M4 width between relay mounting holes: 48mm minimum width between mounting holes on the bottom surface: 64mm height: 50mm width 50mm length of the lower base: 80mm length of the upper base: 60mm https://elecena.pl/product/25569134/ssr-solid-state-relay-aluminum-heatsink 2024-03-12 https://elecena.pl/product/25569134/ssr-solid-state-relay-aluminum-heatsink 2025-10-29
