Product DescriptionETL5-63B Residual Current Circuit Breaker with Overcurrent ProtectionETL5-63B Type B RCBO (Residual Current Circuit Breaker with Overcurrent protection) is a combined protective device that integrates residual current protection (RCD) and overcurrent protection (MCB), with a rated current up to 63A. It supports single-phase 230/240V and three-phase 400/415V systems, features a 10kA breaking capacity, and meets IEC61009-1 and IEC62423 standards.
Type B RCBOs are specifically designed to detect smooth DC residual currents, as well as AC and pulsating DC currents. This makes them ideal for applications such as industrial environments with variable speed drives, solar panel systems, EV charging stations, commercial distribution boards, and residential installations where enhanced earth leakage protection is required.

| Tripping Sensitivity | |
| 30mA | This is the most commonly used protection level in homes and commercial buildings, and is suitable for socket protection in general residential environments, offices and commercial places. |
| 100mA | Usually used in situations where personal protection requirements are not as strict as 30mA, or for equipment protection such as air conditioning systems, industrial equipment, etc. |
| 300mA | Mainly used for fire protection, such as distribution boards and the general protection of large electrical equipment. |
