GB/T 27746-2011 Technical specification for metal oxide varistors(MOV) used in low-voltage apparatus
Abstract
This standard specifies the requirements for MOVs used in low-voltage electrical equipment, including:
——Definitions;
——Classification;
——Rating values;
——Conditions of use;
——Technical requirements;
——Test methods;
——Inspection rules.
This standard applies to metal oxide varistors (hereinafter referred to as MOVs) used in electrical equipment with an AC voltage not exceeding 1,000 V (rms) and 50/60 Hz, and/or a DC voltage not exceeding 1,500 V, for suppressing transient overvoltages and protecting the safety of electrical equipment.
Metal oxide varistors used in low-voltage surge protectors shall comply with the requirements of GB/T 18802.331.
