ABB DC contactor GAF is mainly used for making and breaking DC current in various occasions, especially for making and breaking the DC side current of photovoltaic inverters. Widely used in solar energy systems and other DC systems, such as urban rail, subway, charging piles, energy storage battery packs, uninterruptible power supply, communication industry, etc.
Rated working voltage up to 1000V DC (IEC),
Comply with UL508, rated working voltage 600V DC.
2. Flexible application
The wide coil operating voltage range, although there are few specifications, can cover all applications.
3. High efficiency and energy saving
The GAF DC contactor uses the same electronic coil technology as the AF contactor, which reduces the power consumption of the coil. Compared with the traditional contactor, the energy saving efficiency of maintaining power consumption is 5-10 times that of the traditional one.
4. Stable and reliable
Based on the technology recognized by AF, it is undoubtedly tested in practice.
Insensitive to voltage drop, even if the low-end voltage is reduced by 55% of the rated voltage value and a 20ms voltage drop occurs, the contactor remains in the pull-in state and is not released. The wide voltage characteristic completely avoids contactor vibration and contact welding Problems, enhance the reliability of the contactor and extend its service life
5. Silent work
Regardless of whether the external is AC or DC, the contactor coil works in a DC environment, eliminating the noise generated by the AC coil.
6. Easy to use
The external dimensions are consistent with AF contactors of the same specifications, and the selection and installation are barrier-free.
Card attachment, common with AF contactor.
Compact exterior design with modern atmosphere
Switch-type operating characteristics, reliable operation, stable performance, low coil power consumption
Complies with IEC and cULus standards
The external dimensions are the same as the AF contactors of the same specifications
Rated working voltage up to 1000VDC (IEC), rated current up to 2050A (DC-1 working condition)
When the contactor coil is energized, the coil current generates a magnetic field, which causes the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the contact action: the normally closed contact is opened, and the normally open contact is closed, and the two are linked. When the coil is de-energized, the electromagnetic attraction force disappears, and the armature is released under the action of the release spring to restore the contact: the normally open contact is opened, and the normally closed contact is closed.
In addition to solar energy systems, ABBGAF series contactors can also be widely used in other DC systems, such as urban rail, subway, charging piles, energy storage battery packs, uninterruptible power supply, communication industry, etc., is the best choice for DC applications.
