Warning:
The specification quoted is only for ohmic loads. Overvoltages occur when switching inductive loads (e.g. coils,
transformers, motors) which can lead to EMC problems and, in certain cases, to the destruction of the relay
contact. Appropriate measures (e.g. RC-circuits or varistors) must be taken to suppress these overvoltage spikes at
the load.
