2、 Product performance

Explosion proof performance

The explosion-proof mark of the product is ExdeIICT4 Gb or ExdIIBT6 Gb, which strictly complies with the national GB3836 series explosion-proof standards. The structural design of the explosion-proof shell combined with the increased safety wiring chamber effectively prevents the internal arc from propagating outward, ensuring safe operation in hazardous areas containing explosive gases or vapors. The explosion-proof surface is precision machined and tightly matched, capable of withstanding internal explosion pressure without damage.

protective performance

The protection level reaches IP65, which can prevent dust from entering and withstand water spray from any direction. For outdoor or humid environments, the optional IP66 protection level can withstand strong water spray or wave impact. The box adopts a fluorine rubber sealing strip door cover compression structure, which does not age after long-term use and has a long-lasting and stable protective effect.

Electrical performance

The rated voltage of the product is AC 220V or 380V, and the rated current range is customizable from 10A to 800A. The number of branches can be configured with 2 to 12 circuits, supporting independent control with main switch and branch. The short-circuit breaking capacity can reach 6kA to 50kA depending on the brand of circuit breaker configured. It can be equipped with multifunctional electric meters, leakage protectors, surge protectors and other electrical components to meet different usage needs.

environmental adaptability

The product can operate normally in an ambient temperature range of minus 20 degrees Celsius to plus 40 degrees Celsius, with a relative humidity not exceeding 95%. Suitable for outdoor, humid, highly corrosive and other harsh environments, with stable and reliable performance.
