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.

Classification

1. Number of pole: 1P, 2P
2. Releasing characteristics: C type
3. Rated current: 1, 3, 6, 10, 16, 20, 25, 32, 40, 50, 63A
4. Rated operating voltage: 220V/440V

Normal operating conditions and installation conditions

1. Ambient temperature: -5℃~+40℃, average temperature within 24h does
not exceed +35℃;
2. Altitude of installation place: does not exceed 2000m;
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.
4. Grade of pollution: 2
5. Installation condition: it should be installed at the places of without obvious
impact and vibration as well as the medium without danger (explosion).
6. Installation mode: adopts TH35-7.5 installation rail
7. Installation category: II, III

Model No.

Main technique parameter

Over-current releasing characteristics should confirm to table 1 when the circuit breaker is at normal installation condition and basic temperature of 30-35℃.
