Series Overview
Scope
• HUM18NL-63 Residual Current operated Circuit-Breakers are suitable for AC 50Hz circuits with rated voltage 230V and rated currents up to 63A. They provide protection against electric shock, overcurrent for building circuits/equipment, and fire hazards caused by ground fault currents from insulation failures.
• Complies with GB/T 16917.1 "Household and similar uses – Residual current operated circuit-breakers with integral overcurrent protection (JXCBO) – Part 1: General rules".
Operating Principle and Features
• When leakage current I△ reaches the preset threshold, the device instantly trips to cut power, providing leakage/shock protection while simultaneously safeguarding against circuit overloads and short circuits.
• Visual indicators:
- Green: Contacts open (OFF position)
- Red: Contacts closed (ON position)
- Red: Residual current tripping status
• Compatible accessories: Shunt releases, auxiliary contacts, alarm contacts, under-voltage releases, over-voltage releases, under/over-voltage releases – enabling smart applications.
Operating and Installation Conditions
• Ambient temperature: -5℃ to +40℃; 24-hour average ≤ +35℃
• Altitude: ≤2,000m
• Relative humidity:
• ≤50% at +40℃; higher humidity permitted at lower temperatures.
• Maximum monthly average relative humidity ≤90% (monthly average temperature ≤ +25℃) with anti-condensation measures.
• Pollution degree: Level 2
• Installation category: II
• Mounting: TH35-7.5 standard rails
• External magnetic fields: ≤5 times Earth's magnetic field
• Orientation: Vertical installation (handle upward for ON position)
• Environment: No significant shock/vibration
Usage and Maintenance
• Safety limitations:
- Cannot protect against electric shock from simultaneous contact with two live conductors.
- Input terminals → power supply; output terminals → load. Reversal burns the trip coil.
- All conductors must pass through the RCBO; bypassing any conductor ("体外循环") disables operation.
• Installation:
- Verify nameplate specifications match usage requirements.
- Use conductors with cross-sections matching product ratings.
• Testing protocol:
- Use certified test instruments only. Prohibit direct grounding/short-circuit tests.
- Never test insulation resistance at output terminals. Disconnect auxiliary power and ensure zero voltage at electronic components.
• Operational checks:
- Press TEST button periodically under energized conditions. Malfunctions require immediate removal.
- After fault-induced tripping (leakage/overload/short-circuit), resolve cause before resetting.
• Prohibited actions:
- Do not adjust preset protection characteristics.
• Environmental protection:
- Never expose to rain/snow during transport, storage, or use.
