The circuit breaker should prove useful in applications such as automotive systems that require overcurrent detection to protect against faulty loads and that also need overvoltage protection to ...

Conductor overload protection is not required where circuit interruption would create a hazard (e.g., a fire pump). Short-circuit protection is still required. Not over 800A You can use the next ...
