GB/T 22710-2008Electronic controller for low-voltage circuit breaker (English PDF)

GB/T 22710-2008 is the English-translated version of 低压断路器用电子式控制器.

GB/T 22710-2008 is the Chinese standard "Electronic controller for low-voltage circuit breaker". Its scope clause reads: 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.
