HZMBz series intelligent molded case circuit breakerDetailed product description：

The HZMBz series intelligent molded case circuit breaker is one of the new types of circuit breakers developed by our company through the introduction of international advanced technology and manufacturing technology. Its rated insulation voltage is 800V, used in circuits with AC 50Hz, rated working voltage of 400V, and rated working current up to 1600A for infrequent switching and motor starting. Circuit breakers have the functions of inverse time limit during extension, inverse time limit during short circuit, fixed time limit during short circuit, instantaneous and undervoltage protection during short circuit, which can protect the circuit and power equipment from damage.
Circuit breakers can be installed vertically or horizontally.

The HZMBz series intelligent molded case circuit breaker cannot be reversed, that is, only 1, 3, and 5 can be connected to the power line, and 2, 4, and 6 can be connected to the load line.
The HZMBz series intelligent molded case circuit breaker complies with the following standards:
IEC60947-1 and GB/T14048.1 General Principles; IEC60947-2 and GB/T14048.2 Low voltage circuit breakers and Appendix F Additional requirements for circuit breakers with electronic overcurrent protection

Main performance characteristics:
The HZMBz series intelligent molded case circuit breaker has three-stage protection function, and the circuit breaker of Class B has complete selective cooperation with other short-circuit devices connected in the same circuit under short-circuit conditions; There are five types of release characteristics to choose from: users can adjust the settings of the release according to the load current requirements; The electronic release is provided by the circuit breaker itself, and the current signal and control power come from the annular current transformer installed inside the circuit breaker; Equipped with warning indication: When the load current exceeds the predetermined current, the illuminated secondary attention on the circuit breaker cover is yellow; Equipped with overload indication: When the load current exceeds the set current, the illuminated secondary on the circuit breaker cover is red; Equipped with a dedicated overload alarm function, the circuit breaker does not trip when the load current is overloaded, and outputs a passive contact signal to drive the corresponding alarm device;
The external dimensions are the same as those of the HZMB series molded case circuit breaker, and the installation is interchangeable.
