EKL6-100B+ Type B+ Residual Current Circuit Breaker (RCCB) suitable for 230/240V (1P+N) or 400/415V (3P+N) power systems, with a rated current up to 100A. Designed to detect AC leakage currents, pulsating DC leakage currents, smooth DC leakage currents, composite waveform leakage currents, and high-frequency leakage currents up to 20 kHz with a maximum tripping threshold of 420 mA. The switches therefore provide better fire protection.
 |
Type AC RCDs detect slowly increasing sinusoidal AC residual currents. |
 |
Type A RCDs detect AC leakage currents and pulsed DC leakage currents below 6mA. |
 |
Type B+ RCDs detect all types of residual current - AC, DC, mixed, and smooth - at frequencies up to 20kHz and trip at a kHz maximum of 420mA, offering superior fire protection. |
| 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 general protection of large electrical equipment. |
Type B RCDs - Standard values of break time and non-actuating time for residual direct currents which result from rectifying circuits and for
residual smooth direct current.
