Question

What happens when the maximum allowable coil voltage is exceeded?

Answer



When voltage is applied to the coil, the coil resistance produces heat. When current is applied continuously, the temperature rises and the maximum allowable voltage is determined. If this voltage is exceeded, the coil may burn.

The maximum allowable voltage is the maximum voltage that can be applied to Relays coil; it is not the continuous allowable value.
