Usage and its scope of application RDX30-32 MCB is suitable for the protective distribution circuit of AC 50Hz (or 60Hz), rated operating voltage up to 220V (230V), rated current up to 32A, rated short-circuit breaking capacity does not exceed 4500A, as the use of circuit's infrequently connecting, breaking and switching, with the functions of over-load and short-circuit protection. Circuit breaker confirms to GB10963.1 standard. Model and its implication Rated current of frame size (A) Design serial No. MCB Enterprise code Normal operating condition and installation condition 3.1Ambient temperature: -5ÿ~+40ÿ; Average value in 24h does not exceed +35ÿ. 3.2 Altitude height of Installation places does not exceed 2000m. 3.3 Condition of atmosphere When it is the highest temperature +40ÿ, the relative humidity does not exceed 50%, and it allows a certain high relative humidity when it is at relatively low temperature. For example, it reaches 90% when 20ÿ, and it should take special measurements when there occurring condensation due to the temperature variation. 3.4 Pollution grade: 2 3.5 Installation condition: Installing at the places that without obvious impact and vibration, as well as the medium without danger (explosion). 3.7 Installation category: II, III grade Main technique parameter 4.1 Number of pole: 1P+N 4.2 Releasing type: C type 4.3 Rated current: 6, 10, 16, 20, 25, 32A 4.4 Rated operating voltage: 220V(230V) 4.5 Over-current releasing characteristics: under the normal installation condition and reference temperature (30~35)ÿ, the over current releasing characteristics confirms to table 1.
