► Usage and its scope of application 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: -5y~+40y, average temperature within 24h does not exceed +35y; 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 +40y, and it is allowed relatively high relative humidity when it is at relatively low temperature, for example, it reaches 90% when it is at 20y. It should take measurements when there occurred condensation on the product due to the temperature variation. 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 4.2 Releasing characteristics: C type 4.4 Rated operating voltage: 220V/440V

► Main technique parameter 5.1 Over-current releasing characteristics should confirm to table 1 when the circuit breaker is at normal installation condition and basic temperature of 30-35y. ► External and installation dimension External and installation dimension map of circuit breaker 1) Model and specification, for example, RDX6-63/DC MCB 2) Number of pole, for example, 2P 3) Rated current, for example, 25A 4) Releasing type, for example, C type 5) Ordering quantity, for example, 1000 pcs For example, RDX6-63/DC, 2P, C40, 1000pcs for ordering RDX6-63, the rated current is 40A, 2P, C type, and...
