DCoverloadshort-circuit

RDX6-63/DC MCB is suitable for the DC 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 and IEC60898-1 standards. Normal operating condition and installation condition 3.1 Ambient temperature: -5ÿ~+40ÿ, average temperature within 24h does not exceed +35ÿ; 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 +40ÿ, and it is allowed relatively high relative humidity when it is at relatively low temperature, for example, it reaches 90% when it is at 20ÿ. 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
