Scope application
YJB2-125GQ overvoltage and undervoltage reclosing miniature circuit breaker can perform real-time detection of power supply voltage, achieve automatic disconnection protection for overvoltage or undervoltage, and automatically reclose after the power supply voltage is restored, ensuring safe operation of negative equipment within the normal voltage range. Widely used in civil buildings, commercial real estate, power grid voltage, unstable photovoltaic power generation, or protection of equipment sensitive to voltage fluctuations.
The product complies with JGJ242-2011 “Code for Design of Residential Buildings” and “Standard for Self resetting Overvoltage and Undervoltage Protectors (OUPA)”.
Model Meaning
Normal working conditions
1. The surrounding air humidity is -40 ℃~+85 ℃, and its average value within 24 hours does not exceed+35 ℃. 2. The altitude shall not exceed 2000m.
3. The relative humidity of the air at the installation site under atmospheric conditions shall not exceed 50% at a maximum temperature of+40 ℃; Higher relative humidity is allowed at lower temperatures, with the average lowest temperature of the wettest month not exceeding+25 ℃ and the average maximum relative humidity of that month not exceeding 90%. And taking into account the condensation that occurs on the surface of the product due to temperature changes.
4. Pollution level: Level 2.
5. Installation category: CategoryII
6. Installation method: Adopting international standard guide rails.
PRODUCT FUNCTION
Suitable for detection and protection in two-phase and four phase overvoltage and undervoltage situations, with a wide range of minimum opening voltage of 60VAC, overload and short circuit protection, high breaking capacity, and automatic closing function after voltage recovery.
Indicator lights: The power indicator light, overvoltage indicator light, and undervoltage indicator light share the same light. When the voltage is normal, they display a red constant light, a red single flash when overvoltage occurs, and a red double flash when undervoltage occurs. The product is composed of a small 1P (18mm) intelligent electric operation and a 2P/4P small circuit breaker, with manual and automatic switching. When the switch is switched from automatic mode to manual mode, the switch automatically detects the power supply voltage. If the voltage is normal, it enters the allowed closing state and allows manual closing.
