Description
The OMW1 series intelligent circuit breaker is a cutting-edge solution suitable for AC circuits of 50/60Hz with rated voltages of 400V and 690V, and a rated current capacity of up to 6300A. This intelligent circuit breaker is primarily used for distributing electrical energy and safeguarding circuits and power supply equipment from overload, under-voltage, short-circuit, and single-phase earthing. Thanks to its intelligent and selective protection functions, the OMW1 series enhances the reliability of power supplies and prevents unnecessary power failures. It is ideal for use in power stations, factories, mines (for 690V applications), and modern high-rise buildings, especially within the distribution systems of intelligent buildings. Compliant with IEC60947-2 standards, this breaker ensures top-tier performance and safety.
