Abstract
An electronic circuit breaker is configured to provide a fail-safe mode. It comprises at least one overvoltage component, a temperature sensor attached to the at least one overvoltage component and a sensing and control circuit configured to monitor temperatures of the at least one overvoltage component. There are two criteria to decide if the electronic circuit breaker should open, when either criterion is met. The first criteria is if monitored temperatures exceed max safe temperature at any time and the second criteria is if the monitored temperatures increase at two different time moments during start up.

An electronic circuit breaker (ECB) configured to provide a fail-safe mode, comprising:
- at least one overvoltage component;
- a temperature sensor attached to the at least one overvoltage component;
- and
- a sensing and control circuit configured to monitor temperatures of the at least one overvoltage component,
- wherein there are two criteria to decide if the electronic circuit breaker should open, when either criterion is met, and
- wherein the first criteria is if monitored temperatures exceed max safe temperature at any time and the second criteria is if the monitored temperatures increase at two different time moments during start up.
A method of providing a fail-safe mode in an electronic circuit breaker (ECB), the method comprising:
- providing at least one overvoltage component;
- providing a temperature sensor attached to the at least one overvoltage component;
- and
- providing a sensing and control circuit configured to monitor temperatures of the at least one overvoltage component,
- wherein there are two criteria to decide if the electronic circuit breaker should open, when either criterion is met, and
- wherein the first criteria is if monitored temperatures exceed max safe temperature at any time and the second criteria is if the monitored temperatures increase at two different time moments during start up.
