Function 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 protective circuit with voltage-sensitive resistors that ensure 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 in the internal surge protector components, the internal circuit breaker immediately breaks the circuit, extinguishing the green status indicator light. 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 using a mounting clip. They can be connected to a remote signal indicator unit via the provided plug-in connectors.
