Table 1 note: 1 listed in table 1 specification, but according to the users in a circuit breaker in table 1 shall not exceed the specified in each project. 2 shell frame, 225 100A level (250) A circuit breaker, each group of auxiliary contacts for A drive, A closed, the rest of the circuit breaker from each group to often open and closed contacts. 3 1250Y except dc voltage is owed to the tripping device, the level of the breaker is owed voltage tripping device and shunt tripping device, the voltage ac 380V, dc, there is 220V 110V, one 220V four. 4 the alarm contacts are always open for a head, a closed touch, 5 levels of shell frame 100A without 248, 258, 278, 348, 358, specifications, in the 225A cawkell without 258 and 358 specifications. 6 for double tripping device, with the instantaneous tripping device and hot tripping device of tripping device. Main technicApplicable scope CJDL -01series plastic casing type breaker (hereinafter referred to as the breaker) is mainly used in ac frequency 50Hz, rated current 16A roller to 630A (800A) rated voltage, insulation, rated voltage to 500V and 400V in distribution network, distributed and electricity lines and electric equipment as the overload short-circuit and less voltage protection. Under normal circumstances, the breaker can also be a line of frequent changeover, 400A and level of shell frame can also be used to protect electromotor and circuit breaker less frequent motor starter. With this in GB14048.2-2001 libyans standard requirements. The normal working conditions Ambient air temperature: (1) shall not exceed the limit of ± 40 ° c, (2) limit not more than 5 ° c, (3) 24h mean not exceed + 35 degrees Celsius, Height: the site installation does not exceed altitude 2000m, Atmospheric conditions: air relative humidity in the air temperature of 40 ° c + + cycle when no more than 50%, At lower temperatures can have high humidity, in the wet months for the average monthly minimum temperature, the c + + 25 months mean maximum relative humidity is 90%, and considering the temperature changes in product because of the condensation on the surface. Pollution levels: pollution level 3, in annex pollution levels within the circuit breaker for 2. Install category: five categories. Installation conditions: mounting surface and the vertical no more than 5 °al parameters
