1. What is the GYR10NE?
The GYR10NE is an electronic Residual Current Operated Circuit Breaker with Integral Overcurrent Protection (RCBO). It combines the functions of an MCB (Miniature Circuit Breaker) and an RCCB (Residual Current Circuit Breaker) into a single, highly compact 18mm wide device.
2. What functions does it provide?
It provides comprehensive electrical protection, including:
• Earth Leakage Protection: Quickly cuts off power to prevent electric shock to personnel.
• Overload Protection: Prevents cables from overheating due to excessive current draw.
• Short Circuit Protection: Instantly breaks the circuit during a short circuit to prevent fire hazards and equipment damage.
3. What are the key parameters affecting selection?
When selecting the right GYR10NE for your application, consider the following:
• Rated Current (In): Choose from 6A to 40A based on your circuit load.
• Rated Residual Action Current (IΔn): 30mA (0.03A) is standard for human life protection, while 100mA and 300mA are used for equipment and fire protection.
• Trip Curve: Curve B (for resistive loads like lighting) or Curve C (for inductive loads like motors).
• Action Type: Type AC (for standard AC leakage) or Type A (for AC and pulsating DC leakage).
4. What options are currently available?
The GYR10NE series offers a wide range of configurations:
• Current Ratings: 6A, 10A, 16A, 20A, 25A, 32A, 40A.
• Leakage Sensitivity: 0.03A, 0.1A, 0.3A.
• Tripping Characteristics: B Curve, C Curve.
• Leakage Types: Type A, Type AC.
5. What standards does it comply with, and which markets is it designed for?
The GYR10NE complies with strict international standards including IEC/EN 61009-1 and GB/T 16917.1. It also carries the CE mark and is ROHS 2.0 compliant. It is designed for global markets and is suitable for industrial, commercial, high-rise, and residential installations.
6. What are the installation precautions?
• Wiring Sequence: Always connect the Neutral (N) line first, and disconnect it last during maintenance.
• Wiring Capacity: The terminals accept wire cross-sections from 0.5mm² to 16mm².
• Tightening Torque: Ensure terminal screws are tightened to 1.2N·m to prevent arcing or overheating.
• Environment: The device has an IP20 protection class, meaning it should be installed inside an appropriate distribution box protected from moisture and heavy dust.
