NC Circuit Breaker
As the professional manufacturer in China, XENHO would like to provide you high quality NC Circuit Breaker, which is a safety protection device designed to remain in an open (disconnected) state under no-current or power-loss conditions. It only closes automatically when the power supply is stable and no fault is detected.
What is an NC Circuit Breaker?
XENHO factory’s customized NC Circuit Breaker is a protective device designed to remain in an open (disconnected) state under normal no-current or power-loss conditions; it automatically closes only upon detecting that stable power supply to the line has been restored and that no faults are present. This design effectively mitigates safety hazards associated with sudden power restoration, making it particularly suitable for remote-controlled systems, unmanned power stations, and industrial environments with exceptionally stringent safety requirements, thereby ensuring a controllable and reliable system restart process.
Key Advantages
1. High-Sensitivity Electromagnetic Trigger
High-sensitivity electromagnetic mechanism can ensure microsecond-level response times during overloads and short circuits, effectively isolating faults before they escalate into fires or cascading equipment failures.
2. Integrated Multi-Layer Protection
Over-voltage & Over-current Protection: Safeguards sensitive electronics from power surges.
Short-Circuit Protection: Interrupts fault currents up to 85kA.
Leakage Protection: Detects residual currents to prevent electric shock.
Built-in Self-Diagnosis: An internal module continuously monitors device health. If an internal fault is detected, it actively cuts off the output and triggers an alarm, supporting remote fault uploading to monitoring platforms for immediate IT or maintenance intervention.
3. Good Durablity
With an IP67 protection rating and an operating temperature range of -25°C to +85°C, this breaker is built for the harshest industrial environments.
Applications
The NC Circuit Breaker is widely used in:
Unattended power stations
Remote-controlled electrical systems
Industrial automation lines
Renewable energy systems (solar/wind)
Critical infrastructure requiring safe restart control
