Summary: This standard provides for low voltage circuit breaker with electronic controller (hereinafter referred to as controller) classification, structure, performance requirements, test methods and inspection rules. This standard specifies the controller includes a signal acquisition unit (including current sensors), processing and execution unit (including release components), and should have at least one line to be protected by the energy generated from the raw power. This standard specifies the controller for AC rated voltage not exceeding 1000V, 50Hz or 60Hz frequency used in the circuit breaker is used to protect circuits and electrical equipment from overcurrent and other faults affect its safe operation (such as undervoltage, ground, broken equal) hazards that can have a reasonable man-machine interface, self- diagnosis and treatment functions, and give full play to advantages of electronic technology and other optional features.

1 General

1.1 Scope This standard specifies the applicable low voltage circuit breaker electronic controller (hereinafter referred to as controller) classification, structure, performance requirements, test Methods and inspection rules. This standard specifies the controller includes a signal acquisition unit (comprising a current sensor), the processing and execution unit (comprising decoupling element), and to It should have at least a protected line generated by the self-generated energy supply. The controller in this standard applies to the rated voltage does not exceed AC 1000V, 50Hz or 60Hz frequency is broken circuit used Circuit breaker to protect electrical lines and equipment from overcurrent and other faults affect its safe operation (such as undervoltage, ground fault equal) Harm, and may have a reasonable man-machine interface, fault diagnosis and self-handling functions, and other optional full play to the advantages of electronic technology Features. NOTE. If only controller manufacturers and their supporting breaker, breaker after long supporting compliance with the relevant standards and GB 14048.2-2008 It applies, the controller does not have to be tested separately in accordance with this standard. 1.2 Normative references The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents.
