For enhanced surge protection on phase, neutral, and ground lines, greater safety is ensured.

Function and Application Fields

OBO FLD surge protectors are overvoltage protection components for engineering control systems, signal loop circuits, transmission lines, and computer systems.

The surge protector in the VF series features 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 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 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 a 35mm standard rail using a clip. Remote signal indicators can be connected through the provided plug-in connectors.
