250A three phase electrical fire prevention current limiting protector

In addition to core short-circuit current limiting protection, this device integrates multiple intelligent functions to form a comprehensive electrical safety monitoring system.

● Overload Protection: Triggers current limiting when line current exceeds the rated value for a sustained period.
● Overtemperature Protection: Monitors the unit's own temperature or cable temperature, activating protection when overheating occurs.
● Multifunction Monitoring: Real-time detection and display of various electrical parameters including three-phase voltage, current, frequency, and residual current (leakage).
● Smart Alarm: Features audible and visual alarms; uploads fault information to cloud platforms or backend systems via 4G, WIFI, or RS485 for remote monitoring.
● Additional Protections: Some models include over/under voltage protection, phase loss protection, and arc fault detection.
