RDM10 Series Moulded Case Circuit Breaker - 1

Series Moulded Case Circuit Breaker Application RDM10 series Moulded case circuit breaker, mainly applied to the circuit of AC50Hz, rated current from 16A to 630A, rated insulation voltage up to 500V, rated operational voltage up to 400V, it used to power distribution and overload, short-circuit,under-voltage protection of circuit and electronic equipment. Under normal conditions, It also can be used to circuit transfer infrequently. And it can be used to protect and start Motor infrequently. This production conforms to Standard of GB14048.2. Application code(2 for Motor-protection; Non for Distribution protection) Release type and Accessory code(see Table 1) Poles: 3P Operation type(Non for handle control, Z for rotation control ) Frame size rated current Design code Moulded case circuit breaker Company code Table 1 Accessory name Auxiliary Shunt Two contact No Alarm Shunt Auxiliary Under release+ groups +Under of access contactrelease contact -voltage Auxiliary -ories Auxiliary -voltage release contact contact release Instan overcurrent -taneous release type Double type Normal operational conditions and installation conditions 3.1 Temperature: no higher than +40 , and no lower than -5 , and the average temperture no higher than +35 . 3.2 Installation location no more than 2000m. 3.3 The relative humidity: no more than 50%, when Temperature is +40ºC. The product can withstand the higher humidity under lower temperature, for instance, when temperature at +20ºC, the product can withstand 90% relative humidity. The condensation that happened because of temperature changes should be taken care in special measurements 3.4 Class of pollution : 3 Class; Accessories in the circuit breaker pollution class: 2 class. 3.5 Main circuit breaker installation type : lll Class; Auxiliary circuit and control circuit installation type : ll Class 3.6 Installation condition: Vertical installation www.chinapeople.com Email: simon@chinapeople.com
