Function and Application Fields

OBO FLD surge protectors are overvoltage protection components used for engineering control systems, signal flow loops, transmission line systems, and computer systems.

The surge protector in the VF series, featuring a voltage-sensitive resistor in the protective circuit, ensures a very low protection level under the limited discharge current of FKA. This circuit includes a gas discharge tube and a zinc oxide varistor, monitored by a thermal fuse. In the event 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 (FS) type, it will activate a floating changeover contact.

Installation

The OBO FLD series surge protectors can be directly mounted on a 35mm standard rail with a clip. Remote signal indicators can be connected via the provided plug-in connectors.
