Solid-State Relays (SSR)
Find solid-state relays (SSRs) by complete model number, including G3NA, G3NB and G3PE listings. Compare control input and load specifications before choosing a replacement.
Send your model or a label photo for help choosing.
Choose the right solid-state relay
- Control input: match the input voltage and AC/DC type. A DC control input does not mean the relay switches a DC load.
- Load side: match AC or DC, voltage range, current and the equipment's load characteristics. Keep the full model suffix when comparing parts.
- Switching and cooling: check zero-cross requirements, mounting and the specified heat sink. Usable current depends on installation and ambient temperature; the headline current rating alone is not enough.
- Order contents: check the quantity and whether a heat sink is included in the individual listing.
Manufacturer selection references: G3NA input, load and heat-sink options and G3PE single-phase model options. These describe model families; confirm the exact offered configuration on the product page.
