    • A modular current sensor and power source unit (10) for duplicating the function of a current transformer is disposed on a conductor (11) of an electrical circuit. Modular current sensor and power source unit (10) includes a current transformer (12), a power supply circuit (14), a current sensor (16), and current source circuit (18). Current transformer (12) provides operating power to power supply circuit (14). Power supply circuit (14) regulates the operating power and provides the regulated operating power to sensor (16) and current source (18). Sensor (16) senses current in phase (11) and provides a signal indicative of the current in phase (11) to current source (18). Current source (18) receives the signal from sensor (16) and drives an output current proportional to this signal to the load circuit via lines (34) and (36). The current output by current source (18) has the attributes of the low power sensor (16) with the ability to provide power to the load circuit.

    • A connection verifying trip unit includes a microprocessor circuit and a terminal electrically connected to the microprocessor circuit. A power source is electrically connected intermediate the terminal and the microprocessor circuit. The terminal is electrically connected to ground when the terminal is connected to the circuit breaker. When the terminal is disconnected from the circuit breaker, the terminal is disconnected from ground and the power source provides an input signal to the microprocessor circuit. In response to the input signal, the microprocessor unit provides an output signal indicating, locally or remotely, that the trip unit has been disconnected from the circuit breaker.
    • 连接验证跳闸单元包括微处理器电路和电连接到微处理器电路的端子。 电源在端子和微处理器电路之间电连接。 当端子连接到断路器时,端子电连接到地。 当终端与断路器断开连接时,终端与地断开,电源向微处理器电路提供输入信号。 响应于输入信号,微处理器单元提供一个输出信号,指示本地或远程地,跳闸单元已断开与断路器的连接。
