The invention discloses an MBUS node cluster based protective device which comprises a power taking circuit, a detection sampling circuit, a controller and an alarm indication circuit. The power taking circuit is arranged in the input end of an MBUS, takes power from the MBUS and supplies power to the controller; the detection sampling circuit is arranged in the output end of the MBUS, and handlesan MBUS fault; the controller is connected with the power taking circuit and the detection sampling circuit and used to determine the MBUS fault; and the alarm indication circuit is arranged on the MBUS and connected with the controller. The MBUS node cluster based protective device is used for point protection among a collection panel, a temperature control valve and a concentrator in central heating, and solves the problem that the whole system enters a protection state when the temperature control valve or collection panel is shorted artificially, and thus, normal operation of the whole system is not influenced ev
