1. Models to be used with a full-wave rectifier can be ordered by adding “-V” after the model number. This rectifier is available only on
models without the zero cross function (e.g., G3H-203SL-V).
2. Product is labelled “250 VAC”.
3. Product is labelled “50 VAC”.

Precautions
Refer to pages 11 to 19 for general precautions.
The SSR case serves to dissipate heat. Install the relays so that
they are adequately ventilated. If poor ventilation is unavoidable, reduce the load current by half.
Protective Component
Since the SSR does not incorporate an overvoltage absorption
component, be sure to connect an overvoltage absorption component when using the SSR under an inductive load.
Connection
With the SSR for DC switching, the load can be connected to either
positive or negative output terminal of the SSR.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
