RT-3 (PA Relay type)

PERFORMANCE
Notes: 1. The value of breakdown voltage and insulation resistance is the initial one.
2. Condensing occurs when the unit relay is exposed to sudden temperature change in a high temperature and high humidity atmosphere. This
may cause some troubles like insulation failure of the socket or the print circuit board. Take care under this condition
3. Below 0°C 32°F, condensing water can freeze and cause socket contact failures and other problems. Take care under this condition.
