What is the purpose of a Cable Limiter?

A Cable Limiter serves a critical protective function in electrical installations by safeguarding the cable's insulation and managing fault currents. When a fault occurs, such as a short circuit or overload, the resulting surge in current can potentially damage the cable's insulation and compromise its integrity. By limiting the amount of current that can pass through the cable, the Cable Limiter helps to prevent overheating and potential fire hazards, ensuring that the insulation remains intact and functional.

This device is especially important in protecting against overcurrents that exceed the cable's rating, as excessive current can lead to insulation breakdown over time. In essence, the Cable Limiter acts as a safety mechanism, allowing for the safe operation of electrical systems by controlling the flow of excessive current and thereby preserving the integrity of the electrical components involved.
