The SG65LE-63 series residual current operated circuit breaker combines MCB functionality with residual current protection. This electric type RCBO features a compact design with reliable performance for various electrical applications.
Key Features:
1. Complies with IEC60898, GB16917.1 standards
2. Rated voltage: 230V/400V AC, 50/60Hz
3. Current range: 1A-63A with multiple pole configurations (1P+N, 2P, 3P, 4P)
4. Breaking capacity: 4KA/6KA
5. Flame-retardant PA66 nylon housing with IP20 protection
6. Mechanical life: 10,000 operations
7. Optional lighting/motor protection curves
Technical Specifications:
The electronic type RCBO integrates zero-sequence current transformer technology with precise electronic control for accurate fault detection. The device provides comprehensive protection against:
- Electric shock hazards (30mA/100mA/300mA residual current settings)
- Circuit overloads
- Short circuit conditions
Operation Principle:
When residual current exceeds preset values or circuit faults occur, the electromagnetic release mechanism activates within milliseconds to interrupt current flow. The thermal-magnetic trip unit ensures reliable overload protection with time-current characteristics matching B/C/D curve profiles.
Application Scenarios:
Ideal for residential, commercial and industrial installations requiring:
- Personnel protection against electric shock
- Equipment protection from ground faults
- Circuit protection from overload/short circuit
- Infrequent circuit switching operations
