Diskontaktorer

Diskontaktorer are a type of electrical switch designed to interrupt circuits under load. They function similarly to circuit breakers but are primarily intended for manual operation and often for less frequent switching compared to automatic devices. The term "diskontaktor" is derived from the Swedish word for "disconnect switch" and is commonly used in certain regions.

These devices typically consist of a set of contacts that can be opened or closed by a mechanical lever or rotary mechanism. When the contacts are open, the flow of current is interrupted, effectively disconnecting the equipment or circuit from the power source. Diskontaktorer are often employed as isolation switches to ensure safety during maintenance or repair operations, providing a visible means of breaking the circuit.

They can be found in a variety of electrical installations, including industrial settings, power distribution systems, and some residential applications. The design of diskontaktorer varies depending on their intended voltage and current ratings, as well as the specific environmental conditions they are expected to operate in. Some may feature enclosed housings for protection against dust and moisture, while others are open-type for better heat dissipation. The key characteristic is their ability to safely break electrical circuits when manually operated.
