Autonics SR3-4250 Three-Phase Solid State Relays (Detachable Heatsink Type)
For three-phase load control, the SR3-4250 from the Autonics SR2/SR3 series pairs solid-state switching with a detachable heatsink type body. This construction supports straightforward installation and allows cooling hardware to be replaced independently of the relay. The absence of mechanical contacts means silent, arc-free switching and high tolerance of frequent cycling, suited to industrial heaters, drying equipment, and automated three-phase control panels.
