Through many years of dedicated research on the actual system operation situation and customer needs for new energy at home and abroad, UNITE Electric has developed the GRM3 (DC)-(HU) series of AC and DC Molded Circuit Breakers for New Energy.
Product Characteristic
– for the GRM3-(HU) series Molded Circuit Breaker, The maximum rated voltage is 1140V, and the maximum current is 400A.
– for GRM3-(HU) series Molded Circuit Breaker, in the voltage of 800V, the maximum breaking capacity is 36.5kA, which can ensure reliable short-circuit protection of the system.
– for GRM3DC-(HU) series Molded Circuit Breaker, The maximum rated voltage is 1500V, and the maximum current is 400A.
– for GRM3DC-(HU) series Molded Circuit Breaker, in the voltage of 1500V, the maximum breaking capacity is 20kA, which can ensure reliable short-circuit protection of the system.
Standard
GRM3(DC)-(HU) series AC/DC molded case circuit breaker meets the following standards IEC60947-1 GB/T14048.1 General Provisions IEC60947-2 GB/T14048.2 circuit breaker
Applied Environment
- The altitude is not higher than 2,000 m;
- It is resistant to damp air (three-proof type)①
- It is resistant to the influence of salt fog and oil fog (three-proof type);
- It is resistant to the influence of mold (three-proof type);
- In a medium without explosion risk, the medium is not enough to corrode the metal and destroy the insulation of the gas and conductive dust.
Note: the three-prevention products should be specially customized, please indicate TH.
