RDX65-63 Series Miniature Circuit Breaker Usage and its scope of application RDX65-63 MCB is suitable for the distribution circuit of AC 50/60Hz, rated voltage up to 400V, rated current up to 63A, rated short-circuit breaking capacity does not exceed 6000A, as the use of circuit's infrequently connecting, breaking and switching, with the functions of over-load, short-circuit protection. Meanwhile, it has strong auxiliary function modules, such as auxiliary contacts, contacts with alarming indication, shunt releasing, under-voltage releasing, and remote release control etc. modules. This product confirms to GB10963.1 standards. Rated current (A) Design serial No. MCB Enterprise Code Normal operating condition and installation condition 3.1 Ambient temperature: -5℃~+40℃, average temperature within 24h does not exceed +35℃; 3.2 Altitude of installation place: does not exceed 2000m; 3.3 Relative humidity does not exceed 50% when it is at highest temperature of +40℃, and it is allowed relatively high relative humidity when it is at relatively low temperature, for example, it reaches 90% when it is at 20℃. It should take measurements when there occurred condensation on the product due to the temperature variation. 3.4 Grade of pollution: 2 3.5 Installation condition: it should be installed at the places of without obvious impact and vibration as well as the medium without danger (explosion). 3.6 Installation mode: adopts TH35-7.5 installation rail 3.7 Installation category: II, III Classification 4.1 Number of pole: 1P, 2P, 3P, 4P 4.2 Releasing characteristics: C type, D type (B type can be customized according to requirements) 4.3 Rated current: 4, 6, 10, 16, 20, 25, 32, 40, 50, 63A 4.4 Rated operating voltage: 230V/400V
