ONCCY Over/Under Voltage Protector (3P+N, 100A, 230V)

Intelligent overcurrent protection: Automatically trips the supply when an overcurrent fault occurs in the circuit; after current returns to normal, it automatically recloses according to the userset delay, requiring no manual intervention.

Antitransient interference: Does not misoperate under transient or temporary overvoltage conditions, ensuring supply continuity and equipment safety.

Delayed reconnection for unstable voltage: In response to voltage fluctuations or sudden power outages/recoveries caused by poor contacts, the protector reconnects after a userpreset delay time, avoiding impact damage.

Parameter matching: Rated current 100A, rated voltage 230V, suitable for threephase fourwire systems; the delay time can be flexibly adjusted on site.
