Über- und Unterspannungsauslösung

Protects the circuit by tripping the breaker when the voltage either exceeds a set upper limit (overvoltage) or falls below a preset lower limit (undervoltage).

Typical Applications：

Ensures the safety of voltage-sensitive equipment in unstable power supply conditions.

Rated voltage: 230 VAC
Standard: IEC/EN 60947-5-1
Overvoltage trip: 280V ±5%
Undervoltage trip: 170V ±5%
Mechanical status indicator
Ensures safe operation under unstable power supply conditions
