Features and Application Fields

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

The surge protectors in the VF series feature a voltage-sensitive resistor in the protected circuit, which ensures a very low protection level under the limited discharge current of the FKA. The circuit includes a gas discharge tube and a 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 protection device is equipped with a remote signal alarm unit (FS), it will activate a floating changeover contact.

Installation

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