Function and Application Fields OBO FLD surge protectors are overvoltage protection components for engineering control systems, signal flow loops, transmission main systems, and computer systems. The surge protector in the VF series includes a voltage-sensitive resistor in the protected circuit, which ensures a very low protection level under the limited discharge current of FKA. The circuit includes a gas discharge tube and zinc oxide varistor, monitored by a thermal fuse. In case of aging or overload of the surge protector's internal components, the built-in circuit breaker will immediately disconnect the circuit, and the green status indicator will turn off. If the protective device is equipped with a remote signal alarm unit (FS), it will initiate a floating changeover contact.
|
Installation The OBO FLD series surge protectors can be directly mounted on 35mm standard DIN rail using a clip. Remote signal indicators can be connected via the provided plug-in connectors.
