Selection & installation notes
- The generic selection row says 40 A, but normally-closed contacts are limited to 30 A. Do not apply the NO rating to NC paths.
- The source mixes relay-body and socket-assembly dimensions. Treat 49.5 × 95.5 × 97 mm as an assembly reference pending the exact drawing; body mass excludes socket.
- Socket Ui 500 V and its wider temperature range do not increase relay contact voltage or complete-assembly ambient limits.
- Use the load category and verified derating for motors, inductive and capacitive loads. Do not parallel poles to increase current. Isolate all circuits before replacement.
