This is an industrial solid state relay (SSR), manufactured by Celduc in France, housed in a black molded case with a heatsink-style base plate. Unlike a standard single-pole SSR, this is a two-phase (dual-channel) unit — it contains two independent switching channels in one housing, controlling two power poles (labeled A1/B1 and B2 on the input side, with A2 as a shared reference) from a single control signal input. The unit has four main power terminals (large threaded lug/stud terminals for load wiring) and a control input connector at the center (the black connector block with pin contacts visible between the top and bottom terminal rows). Safety/compliance markings on the case include CE, UL/cUL, and a thermal warning triangle (icon 10102, referring to a heatsink/thermal caution).
