📚Miniature Circuit Breaker Manual

1. Product Overview

The LVMA LMB1LE-63 RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combines the functions of an MCB (Miniature Circuit Breaker) and RCD (Residual Current Device) in a single modular unit. It provides simultaneous protection against overload, short-circuit, and dangerous earth leakage currents, making it ideal for residential, commercial, and light industrial installations.

Key Specifications

Parameter Value
Model LMB1LE-63
Rated Voltage 400V~ 50Hz
Rated Current 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A
Rated Residual Current 30mA / 100mA / 300mA (IΔn)
Breaking Capacity 3000A / 6kA (per variant)
Tripping Curve B (lighting/resistive), C (mixed/motor), D (high-inrush machinery)
Trip Time ≤0.1s
Poles 1P+N / 2P  / 3P / 3P+N / 4P
Certifications CCC, IEC 60898
Test Function Monthly test button with leakage indicator
IP Rating IP20 (finger-safe terminals)

2. Core Features

  • Dual Protection in One Unit

    Combines overcurrent (overload/short-circuit) and residual current (earth leakage) protection, eliminating the need for separate MCB and RCD units.

  • Fast Response for Safety

    ≤0.1s tripping speed ensures immediate disconnection during faults, preventing electric shock and fire hazards.

  • Monthly Test Button

    Integrated test button (labeled “Press Once Monthly”) allows users to verify the leakage protection function works properly.

  • Clear Leakage Indicator

    Visual indicator confirms residual current trips for easy troubleshooting.

  • High Breaking Capacity

    Withstands up to 6kA short-circuit currents, suitable for demanding electrical systems.

  • DIN Rail Mountable

    Standard modular design fits all common distribution boards, saving installation space.


3. Applications

  • Residential distribution boards (homes, apartments)
  • Commercial buildings (offices, shops, hotels)
  • Light industrial facilities

    Power distribution panels for critical equipment

  • Renovation and retrofitting projects

4. Why Choose LVMA?

  • Quality Certified

    Compliant with international standards (IEC 60898) and Chinese CCC certification for safety and reliability.

  • Competitive Pricing

    Direct factory pricing for bulk orders, ideal for distributors and contractors.

  • Fast Lead Times

    Ready-to-ship inventory and short production cycles to meet your project deadlines.

  • Customization Available

    Support for custom branding, packaging, and technical specifications to match regional requirements.


5. FAQ

Q: What is the difference between RCBO and RCCB?

A: An RCBO combines the functions of an MCB (overload/short-circuit protection) and an RCD (leakage protection) in one device, while an RCCB only provides residual current protection and requires a separate MCB for overcurrent safety.

Q: How often should I test the RCBO?

A: The test button should be pressed once a month to ensure the leakage protection function is working correctly, as indicated on the device.

Q: What does the “C63” marking mean?

A: “C” refers to the C-curve trip characteristic (standard for general-purpose circuits), and “63” indicates the maximum rated current of 63A.
