Frakoblers

Frakoblers is a term used in electrical engineering to describe devices and assemblies that are designed to disconnect an electrical circuit or subsystems from a power source. In some contexts the term is associated with isolation switches or disconnectors used to provide a clearly visible break in all current-carrying paths, enabling safe maintenance and clear de-energization of equipment. The word’s usage can vary by region and industry, and it is sometimes considered synonymous with a general isolator or disconnector.

Design and function

Frakoblers typically include a pair of contacts, an actuator to open or close the contacts, and a housing or enclosure that provides protection and safety. They may be operated manually, via a handle or switch, or automatically through remote control, automation systems, or protective relays. Many designs incorporate interlocks, padlocks, or mechanical interlocking to prevent accidental re-energization while work is in progress. Electrical ratings indicate the maximum voltage, current, and fault conditions the device can safely handle, and many units are designed to withstand arcing and provide safe dissipation of energy during opening and closing.

Applications

Frakoblers are used across power distribution, industrial control panels, substations, and telecommunication or data-center environments. They serve to isolate feeders, equipment bays, or individual circuits for routine maintenance, fault isolation, or safety shutdowns. Proper selection considers voltage level, current, environmental conditions, and required safety interlocks or status indicators.

Safety and standards

Devices in this class are expected to comply with applicable safety standards and national or regional regulations governing electrical isolation devices. Typical considerations include visible open conditions, reliability of actuation, fault-clearing capability, and secure mounting and labeling to prevent accidental energization.
