Functions and Application Fields

The OBO FLD surge protector is a component for overvoltage protection used in engineering control systems, signal loop circuits, transmission line systems, and computer systems.

The surge protectors in the VF series feature a protection circuit with a voltage-sensitive resistor that ensures a very low protection level under the limited discharge current of the FKA. This circuit includes a gas discharge tube and zinc oxide varistors, monitored by a thermal fuse. In the event of aging and overload of the built-in surge protector components, the internal circuit breaker will immediately disconnect the circuit, and the green status indicator light will turn off. If equipped with a remote signal alarm device (FS) type protection, it will activate 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.
