Product Description
··································This link price is only for GRM3DC-630HU-2P 630A DC1500V!···························· Function Introduction
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
Use and Maintenance
Various characteristics and accessories of the circuit breaker shall be fixed by the manufacturer and shall not be adjusted in the use. Under the compliance with custody and use conditions, from the date of 24 months from the manufacturer delivery and in the situation of the circuit breaker intact seals, if the product is damaged or not used normally due to manufacturing quality problems, the manufacturer shall be responsible for replacement and repair without charge.
Applied Environment
1. The altitude is not higher than 2,000 m;
2. It is resistant to damp air (three-proof type)
3. It is resistant to the influence of salt fog and oil fog (three-proof type);
4. It is resistant to the influence of mold (three-proof type);
5. 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.
