RCD10-100/100/4S
100A 4 Pole Type A Selective RCD – 100mA for Delayed Residual Current Protection
This 100A 4-pole Type A selective RCD provides essential residual current protection with a 100mA sensitivity and time delay, ensuring enhanced discrimination in electrical installations. Tested and approved for use with Lewden distribution boards, it is ideal for single-phase and three-phase applications in commercial and industrial environments.
- Compatible with Lewden Distribution Boards: Designed and tested for seamless integration.
- Type A RCD Protection: Detects AC and pulsating DC residual currents for improved electrical safety.
- Selective (Time-Delayed) Operation: Ensures proper coordination with downstream devices, reducing nuisance tripping.
- 4 Pole Design: Provides full protection for three-phase installations, including neutral.
- 100A Rated Current: Suitable for high-power electrical systems in residential, commercial, and industrial settings.
- 100mA Sensitivity: Provides effective leakage current protection while allowing for selectivity in multi-RCD setups.
- Supports Multiple Earthing Systems: Suitable for use in TN-S, TN-C-S, and TT network systems.
