fasesikker

Fasesikker is a Norwegian term used to describe equipment, components, or practices that are designed to reduce hazards related to multiple electrical phases, especially in three-phase systems. While it is not a formal certification, it is commonly used in product documentation and safety notices to indicate that a device includes safeguards against misphasing, phase loss, and improper phase connection.

Typical interpretations of fasesikker include phase sequence detection to ensure motors start in the correct rotation, protection against phase loss or phase imbalance that could damage equipment, automatic disconnection or interlocking if unsafe phase conditions are detected, and clear labeling of connectors and terminals to prevent incorrect wiring. Some implementations combine mechanical interlocks, electronic monitoring, and fail-safe design to limit exposure to live parts during maintenance.

Fasesikker features are particularly relevant for industrial electrical installations, switchboards, motor starters, testing rigs, and other equipment that operates on more than one phase. In practice, manufacturers use the term to signal a product’s emphasis on safety in relation to phase handling, while installers and inspectors interpret it in light of applicable electrical codes and standards.

Users encountering fasesikker should review the specific safety features described in product documentation and verify that the equipment meets local regulations and industry practices. The term conveys intent and risk mitigation, but it does not replace formal verification or compliance testing.
