In general, is it advisable/safe to switch a mechanical relay with the following abstract conditions?
- load voltage << rated switching voltage
- load current > rated current
Relevant Questions
- Relay: higher voltage allowed at lower current? states the following
The current rating is to limit the self-heating of the relay due to its own resistance.
maximum current that the relay can sustain when being opened or closed and not sustain contact damage
My Use Case
I have a mechanical relay (Digi-Key PN 281-6348-ND) with the following specs:
- Switching Voltage:
250 Vac
- Contact Current Rating:
10 A
I would like to use it to PWM control a 12 Vdc
thermoelectric plate (Peltier module) rated to pull up to 15 A
