                                                              switching capabilities for 1500 V DC.










                                            Energy Efficiency
                                            GF contactors offer tailored solutions to enable remote, automatic and energy
                                            efficient switching of 1500 V DC circuits in central PV inverter optimization.
                                            The GF contactors are built with ABB's standard low energy electronic coils for
                                            safe and controlled operation.



                                            Continuous operation
                                            The GF contactor features AF technology with continuous voltage and current
                                            control during the contactors operation. This ensures distinct, safe and energy
                                            efficient operations even in unstable networks. Voltage sags, dips or surges
                                            pose no threat. The GF contactor secures application uptime.



                                            Speed up your projects
                                            ABB's GF contactor complies with all major international standards.
                                            It features AC/DC controlled wide voltage range coils together with easily
                                            accessible coil terminals to make easier and quicker product selection
                                            and installation.
