The circuit breaker is suitable for AC 50Hz/60Hz, rated insulation voltage to 1000V (800V for 125A and below), and rated current to 630A for power distribution and protection of line and power equipment from overload. Short circuit,The hazard of undervoltage and other faults can also be used to control the infrequent operation of the motor.
Circuit breakers are classified into C type (basic type), S (standard type), and H (higher type) according to their rated limit short-circuit breaking capacity. The circuit breaker has the characteristics of small volume, high breaking, and short arcing.
Standard: GB/T 14048.2, IEC 60947-2.
