Self-cooling vacuum circuit breakers (VCBs) that do not require a fan to be mounted on the panel. Available in a wide range, from rated current of 600 to 3,150A. • Compliant with IEC...

Cutting-edge Technologies Using 3D CAD and CAE VCB Structure to Ensure the Utmost Levels of Reliability and Safety Operating Mechanism Through use of thermal fluid analysis, we have realized efficient release of heat to the cylinder-shaped insulation frame covering the VCB main circuit part, enabling a self-cooling mechanism up to a rated current of 3,150A. Greater performance reliability and extension of the lubrication cycle from three to six years through measures for the operating mechanism such as minimizing the number of parts, reducing the number of moving parts, adopting oilless...

Type Selection M2, E2, and C2 Classes Described in the Specifications (IEC62271-100) Classification as for Mechanical Endurance ( M1 and M2 ) The IEC standards broadly divide the mechanical operating test into classes M1 and M2. At the control voltages shown in Table 1, class M1 requires the rated operation sequence to be performed 2,000 times in total while class M2 requires the rated operation sequence to be performed 10,000 times in total. At five times the actuating cycle of class M1, class M2 represents a highly reliable operation class. Table 1 M1 and M2 operating sequence. Control...
