Three-phase current limiting protectorThree-phase current limiting protector
Electrical fire protection current limiting protector is a new type of electrical safety monitoring device that can accurately detect the current of the electrical circuit in real time, and quickly limit the short-circuit current at microsecond level speed to achieve arc extinguishing protection. It integrates multiple functions such as voltage, current, frequency, leakage, temperature, and fault arc detection (optional), and has intelligent analysis capabilities. When an electrical accident occurs in the electrical circuit, the protector can emit sound and light alarm signals or upload them to the cloud backend to promptly remind users to check the fault, eliminate possible electrical hazards, and prevent accidents from happening.
