    Patent number: 6359763
    Abstract: A trip circuit supervision circuit is disclosed for use in combination with a trip circuit comprising a circuit breaker trip coil connected in a supply line from a supply voltage and a trip relay contact connected in series with the circuit breaker trip coil. The supervision circuit is connected across the relay trip contact and includes a current sensing device. During normal operation, the supervision circuit draws a constant current from the supply line independent of supply voltage. Thus, changes in the current measured by the current sensing device enable the integrity of the supply voltage to be checked.
