Selection & installation notes
- Select the exact AC/DC type and input range; do not interchange AC and DC load versions.
- A random-trigger TRIAC cannot be assumed to interrupt AC current immediately. Confirm turn-off timing under the actual load.
- Surge ratings lack waveform and duration and must not be used as continuous or repetitive current limits. Derate for thermal conditions and inrush.
- OFF-state leakage remains present; isolate the load supply for maintenance.
- The page mentions explosion-protection applications without certification evidence. No hazardous-location suitability is established. Request the soldering process and footprint before PCB release.
