- relations between make voltage and ambient temperature at

no load on contacts. Coil temperature and ambient temperature

are equal before coil energizing. Make voltage is not higher than

the value read on Y axis (multiplication of rated voltage).

- relations between make voltage and ambient temperature

after initial coil heating up with 1,1 U , at continues load of I on

contacts. Make voltage is not higher than the value read on Y

axis (multiplication of rated voltage).

- values on Y axis represent allowed overvoltage on coil at

certain ambient temperature and contact load:

- no load

- 50% of rated load

- rated load
