ABB DC Switching Contactors: Type GAF
DC switching contactors, type GAF A compact contactor up to 1000 V DC Brochure
2 DC switching contactors | 1SFC101004B0201 The GAF contactor range A compact and efficient way of DC switching The new GAF range contactors are the latest addition to ABB’s well established A/AF range. This further extends our offering of contactors for DC switching at voltages up to 1000 V DC. The GAF contactors utilize all the well known features of the existing A/AF range such as modern and compact design. In addition all the benefits from the AF coil technology and reliability of a proven contactor design. These contactors are rated for DC-1 or DC general purpose applications according to IEC 1000 V DC or cULus 600 V DC. The new GAF contactors share the external dimensions of its corresponding standard AF contactor. The new GAF range, the world‘s first block contactors with ratings up to 2000 A for 1000 V DC
1SFC101004B0201 | DC switching contactors 3 Features and benefits Powerful• 1000 V DC switching ratings (IEC). • UL (508) rated up to 600 V DC. Flexible• Wide control voltage range (e.g. 100-250 V AC/DC) means less versions covering the entire range. • PLC interface with 24 V DC / 100 mA for GAF/AF400...2050. Efficient• The AF electronic coil interface reduces power consumption 5-10 times at holding compared to conventional contactors. Reliable• The GAF contactor is based on the well proven AF contactor. • Less sensitive to voltage drops due to a drop-out voltage of 55% of the lower nominal value along with 20 ms sag and dip immunity. These features avoid the problems with contactor chattering and welding. • Elimination of contact bounce and chattering provides for increased reliability and service life. Silent • DC powered coil makes the contactor virtually noise free. Easy• The external dimensions of the GAF contactors are the same as corresponding AF contactors making it easy to order and install. • Existing add on accessories for A/AF range of three pole contactors will fit the GAF contactors. The GAF contactor’s ability to break DC up to 2000 A at a voltage up to 1000 V derives from the use of permanent magnets in the arc packages. The magnets enable the contactor to extinguish the powerful electrical arcs that arise between the contact surfaces when breaking DC. Normal AF contactors can break DC up to some extent but since they lack the permanent magnets they will not be able to break DC as a corresponding GAF contactor. 1 L1 3 L2 For Ge nera l Use .

4 DC switching contactors | 1SFC101004B0201 Applications – solar What is PV power? Photovoltaic (PV) power is a renewable energy source converting sunlight directly into electrical energy using PV cells. Large PV systems often consist of following main components: • PV cells (combined to strings, generating the power). • Inverter (one or several, converting the generated DC voltage into AC 50Hz or 60Hz, also including devices for switching, protection and control). • Combiners (junction boxes, including switching devices, with several cables on input and one cable on output). • Trackers (mechanical structure to move the angle of PV cells to follow the sun, increasing system efficiency, also including motors, PLC, communication, protection). • Switching devices and protection devices (to change PV string configuration, protect from over currents, surge voltages and earth faults etc.). • Distribution transformer (transforming low voltage to high voltage, as grid connection often is done on high voltage level).
1SFC101004B0201 | DC switching contactors 5 What is the future of PV power? Solar energy is today the fastest growing segment in renewable energy and is believed to be one of the major energy sources in the future. Factors that vouch for a bright future of solar energy: • Growing climate awareness brings more focus on renewable energy. • Continuously higher legislative demands on increasing the share of green energy. • Intense research and development of the PV technology in order to make it more efficient and easier to produce. Decreased production costs due to higher volumes and improved production technique make it possible to pro- duce low cost PV cells which in turn will expand the market. Why is DC contactors needed? PV plants contain some major application for DC swit-ching, since the electricity produced by the PV panels is DC. Depending on application requirements, different products can be used for switching. Contactors are typically selected for app-lications with the need for remote control and switching at least once per day. Applications Main applications where contactors are used for DC switching are: • Disconnection of the inverter from the PV strings when the output is too low. • Changing the string configuration, e.g. to increase plant efficiency by diverting one or several PV strings to an opti- mal number of converters at low output. This makes it possible to constantly optimize the efficiency of the system. ∼ Block contactor type GAF Block contactor type AF Bar contactor R series Solar PV central inverter PV strings DC AC Grid side
6 DC switching contactors | 1SFC101004B0201 Applications – other There are several other DC-applications in which ABB’s GAF & AF contactors can be efficiently used. Traction Traction vehicles • Urban traction vehicles such as trams, subways, commuter trains etc. • Diesel locomotives • Heating applications Traction wayside • Signaling • Switchgear • Power distribution Batteries The accelerating need for mobile energy and protection against power disturbances in distribution networks is driving the market of batteries forward. The number of applications where batteries can be used is steadily increasing and with that the need of DC switching. Examples of such applications are charging of vehicle batteries, UPS installations, backup and control solutions, etc. Telecom The telecom industry is today facing a rapid increase of data transmission which demands larger and more efficient transmis-sion stations. Larger stations may require higher currents and an increase of voltage in order to reduce energy losses. In this kind of setup compact, efficient and reliable DC switching is needed. Special industry: • DC Drives in e.g. metal refining plants.

Bar contactors can typically be used for higher amps and voltages or other configurations or number of main poles (contacts). 2) For other DC swtiching contactors e.g. GA/GAE75 see catalog 1SBC100122C0202.

The SCPD (Short Circuit Protection Device) must comply with applicable protection rules. • The direction of the current must be as shown on the contactor front label. • Connection bars for connecting three contacts in series are not delivered with the contactor as standard, but are available as accessories. For further information regarding connections see Technical paper. Recommended connection All three contacts connected in series without the load in between. This connection is recommended in systems according to the configurations below.
