CB Certified SG65LE-63 Electric RCBO Circuit Breaker with Overload Protection 1-63A

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
