A circuit breaker is a switching device that performs fault protection on an electric circuit. When the power circuit fails, the circuit breaker trips to open the power circuit.

As shown, the electronics module 120 of the circuit breaker 100 includes a power panel (also referred to as a first circuit board) 122 and a control panel (also referred to as a second circuit board) 132.

The electronic module 120 further includes a controller M1, a first transformer 136, and a second transformer 134 disposed on the control board 132. As shown, phase line L2 passes from first transformer 136 to couple with first transformer 136. The second transformer 134 is a ring transformer, and the phase line L2 and the neutral line L4 pass together in a ring of the second transformer 134 to be coupled with the second transformer 134. Controller M1 is coupled to first transformer 136 and second transformer 134 for obtaining electrical parameters associated with phase line L2 and neutral line L4, such as electrical parameters associated with current and/or voltage on phase line L2 and neutral line L4, from first transformer 136 and second transformer 134.

The double-circuit-board structure provides a very compact and space-saving circuit board structure, and simultaneously ensures that enough electric clearance and creepage distance exist between two circuit boards, thereby ensuring the safety of the circuit breaker.

Meanwhile, for large-sized components in the electronic module 120, i.e., the first transformer 136 and the second transformer 134, since the size thereof in the width direction of the circuit breaker 100 is larger than the distance between the power board 122 and the control board 132 spaced apart in the width direction, an opening 128b is specially provided on the power board 122 to avoid the first transformer 136, and notches 128a, 138a are specially provided on the power board 122 and the control board 132 to avoid the second transformer 134.

As described above, the trip unit 140 of the circuit breaker 100 according to some embodiments of the present invention may include various trip units, such as the trip unit 142 controlled by the controller M1, as well as the magnetic trip unit 144 and the bimetal thermal trip unit 146. These trips are actuated when a corresponding fault occurs in the load circuit of the circuit breaker 100, so that the trip actuator 160 is actuated to separate the stationary and movable contacts of the main contact mechanisms of the phase line L2 and the neutral line L4.

During operation of the circuit breaker, controller M1 continuously monitors the electrical parameters of phase line L2 and neutral line L4 through first transformer 136 and second transformer 134. When a load circuit of the circuit breaker 100 has an electric leakage fault, an arc fault, an overvoltage fault, or the like, the controller M1 monitors the electrical parameter changes of the phase line L2 and the neutral line L4, and determines that the load circuit has the electric leakage fault, the arc fault, the overvoltage fault, or the like. At this time, the controller M1 drives the trip unit 142 to operate, so that the trip actuator 160 is actuated to separate the fixed contact 172 and the movable contact 174 of the main contact mechanism 170 of the circuit breaker 100. When a short circuit fault or an overload fault occurs in a load circuit of the circuit breaker 100, the magnetic trip 144 or the bimetal thermal trip 146 is actuated, so that the trip actuator 160 is actuated to separate the fixed contact 172 and the movable contact 174 of the main contact mechanism 170 of the circuit breaker 100.

Furthermore, according to the present invention, the circuit breaker further comprises a trip indicator, such as an LED. The controller M1 of the circuit breaker 100 is connected to a trip indicator, such as an LED, to indicate to an operator the cause of a trip fault of the circuit breaker when the circuit breaker trips, by, for example, driving the LED to flash at a predetermined frequency or number of times.
