Operation

Capillary :  The liquid within the capillary is transformed to vapour with an abnormal increase in temperature.  The increase in volume acts on a mechanism to open electrical contacts.  The limiter is manually resettable.  In case of damage to the capillary the fail-safe limiter operates automatically.

Bimetal : A snap action bimetal opens electrical contacts with an abnormal increase in temperature.
