The invention discloses an extremely simple simulation circuit breaker circuit, and relates to the technical field of circuit breakers. The switching-on control relay and the switching-off control relay are double-C-type contact relays. A coil end point 14 and a coil end point 13 of the closing control relay are respectively connected with a direct current power supply negative end CN-and a closing control input signal Hz +, and an end contact 9, an end contact 5 and an end contact 4 of the closing control relay are respectively connected with an energy storage power supply positive signal CN +, an end contact 12 and an opening control input signal Fz +; a coil end point 14 and a coil end point 13 of the opening control relay are respectively connected to a negative end CN-of the direct-current power supply and an opening control input signal Fz +, and an end contact 9 and an end contact 1 of the opening control relay are respectively connected with an end contact 5 and a closing control input signal Hz + of
