liberação de perda de tensão

Automatically trips the circuit breaker when the supply voltage drops below a certain threshold or is lost entirely.

Typical Applications：

Protection of voltage-sensitive equipment, prevention of low-voltage operation, and avoiding unintended startups.

•  Rated voltage: 230 VAC
• Automatic reset function
• Standard: IEC/EN 60947-5-1
