YBX4 & YBX5 Series High-Efficiency Flameproof Three-Phase Asynchronous Motors

The YBX4 and YBX5 Series High-Efficiency Flameproof Three-Phase Asynchronous Motors are CCM (Continuous Casting Mould) fundamental products and feature the following characteristics:

• The power ratings and mounting dimensions of this series comply with the International Electrotechnical Commission (IEC) standards, and their corresponding relationships are identical to those specified in the German DIN 42673 standard.
• Based on the standard series, special-purpose versions can be manufactured to suit various operating environments, climatic conditions, corrosion resistance requirements, and other specific needs.
• The efficiency values meet the Grade 2 energy efficiency level as specified in GB 18613-2020 (YBX4 series) and the Grade 1 energy efficiency level (YBX5 series), which are consistent with IE4 (YBX4 series) and IE5 (YBX5 series) of IEC 60034-30.
• The flameproof performance complies with the provisions of GB 3836.1-2010 and GB 3836.2-2010, with an explosion-proof marking of Ex d IIC T4 Gb.
• Suitable for use in explosive gas atmospheres other than coal mines, with a "high" level of protection.
