Functions 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 are equipped with voltage-sensitive resistors in the protection circuit, ensuring a very low protection level under the limited discharge current of FKA. This circuit includes gas discharge tubes and zinc oxide varistors, monitored by a thermal fuse. In the event of aging or overload of the surge protector's internal components, the internal 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) type, it will initiate a floating changeover contact.

Installation

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