Company Introduction:
Dehler Technology Co., Ltd. specializes in producing high and low voltage switchgear, box type substation, cable branch box, outdoor vacuum circuit breaker, isolation switch, grounding switch, load switch and low voltage components and other products.
DLA series of MCCB have the following characteristicsdouble insulation;positive operationisolation functionelectromagnetic compatibility;Multi-faceted installation, the breaker can be horizontal, vertical,lie installed, without any impact on performance;If the altitude below 2000 meters, the breakers don't need to be derated; If above 2000 meters, because of the change of atmospheric environment(air component, dielectric strength, cooling capacity and atmospheric pressure), the main parameters of breaker will be impacted. The following form indicates the main parameters of breaker in different altitude environment.
Circuit Breaker may be used between -25°C and +70°C .the storage-temperature range is -40 °C to +70 °C. The following DLA circuit breakers can stand 100% In without tripping at 50 °C.
-CSAA1 and A2: current to 250A( except A1 125A);
-CSAA3: 300-400A special specifications at 50 °C;
The detail temperature peformance of all DLA circuit breakers, please check characteristic curves and technical parameters.
All of DLA circuit breakers have test button, which can be used for tripping test ,the test operation can be realised only in the closed position.
