UKM30-63S 50A 3P Magnetic Type Molded Case Circuit Breaker AC600V Rated current range10~63A Arcing distance:≤50
Brief Introduction
UKM30 series moulded case circuit breaker (circuit breaker for short) is high-tech products in 21st century with advanced design,high performance,pleasant appearance and delicate dimension. Meanwhile, they are intelligent controlled and developed with microelectronic technology.
Usage & Appliance
The circuit breaker is used in the electrical system of AC 50Hz,related voltage of up to 690V, rated current of up to 800A to prevent the system from overload,short-circuit and under-voltage and to control the infrequent operation of motor.
Weight: 0.75KG
Rated operation frequency (per hour): 120
Standards
It is complied with GB1408.2 and IEC60947-2 section 2 and etc.
Normal operation condition
The circuit breaker could be used in the following working conditions:
A. Ambient air temperature not higher than +40 ℃ and not lower than -5 ℃.
B. Altitude no more than 2000m
C. The relative air humidity is not more than 50% in the max at the temperature of +40 ℃. The higher relative humidity is allowable at the lower temperature. The lowest monthly average temperature not higher than 25 ℃ in the most moist month and the max relative humidity should be no more than 90%.
D. Pollution degree:Grade 3. Three is no explosion factor, corrosive metal and the gas destroying the insulation and the electric dust.
E. Installation type:Ⅲ
F. The terminals of 1,3,5,N1 should be connected with the power supply and the terminals of 2,4,6,N2 should be connected with the load. Reverse wiring is forbidden.
