## Activation status
## Activation specification
## Deactivated:
Before reflow the activation button should not be manipulated with a force greater 5 newton.
## Activated:
Activation after reflow is necessary for the tripping functionality of the RTS. This activation is done by mechanically pressing the activation button with max 50 newton.

## Design-In Principles
- The RTS should be placed as close as possible to the heat source (power semiconductor).
- Max. nominal current depends on ambient temperature and on the PCB track implementation (see Derating Curves).
- The derating curves were generated using a PCB acc. to IEC 60127-4 with a layer width of 20 mm.
- If operating current is higher than allowed, consider using two RTS in parallel. This doubles the max. current value in the derating curve.
