ERW1-1600 Universal Circuit Break
Scope of application
ERW1-1600 (DW50) universal circuit breaker (hereinafter referred to as circuit breaker) has a rated current of 200A to 1000A, and a rated working voltage of AC400V, 690V, 50Hz.
It is mainly used in power distribution networks to distribute electric energy and protect lines and power equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. Under normal conditions, it can also be used for infrequent line conversion. It can provide selective protection and precise action, avoid unnecessary power outages, and improve the reliability of power supply.
It meets the standards: GB/T14048.2, IEC60947-2.
Model meaning
Normal working conditions and installation conditions
a. Ambient temperature
1. The upper limit of the ambient air temperature shall not exceed +40℃, the lower limit shall be -5℃, and the average temperature value within 24 hours shall not exceed +35℃ (unless otherwise specified)
2. For use in ambient air temperature higher than +40℃, the maximum ambient temperature allowed is +60°C according to Table 1 and the capacity reduction. (Refer to Table 1 for the requirements of capacity reduction)
b. Altitude
The altitude of the installation site shall not exceed 2000m; (if it exceeds 2000m, the capacity reduction shall be used, and the requirements of capacity reduction shall refer to Table 2)
c. Limit and atmospheric conditions
When the relative humidity of the atmosphere is within the range of +40℃, the relative humidity of the air shall not exceed 50%. Higher relative humidity can be allowed at lower temperatures, for example, the humidity can reach 90% at 20℃. Special measures should be taken for condensation caused by temperature changes.
d. The pollution level is level 3.
e. Use category B
f. Installation category
1. Circuit breaker installation category IV When the rated working voltage of the main circuit is less than AC400V, the auxiliary circuit installation category is the same as the circuit breaker except for the undervoltage release coil and the booster or power module primary coil used for the intelligent controller. When the rated working voltage of the main circuit is greater than AC and less than or equal to AC690V, the auxiliary circuit needs to be isolated from the main circuit by a transformer. The isolation transformer has a capacity of ≥2kVA and the maximum working voltage of the control circuit is AC400V. The auxiliary circuit installation category is IⅢ.
2. Installation conditions. The circuit breaker should be installed according to the requirements of this manual, and its vertical inclination should not exceed 5.
