1. Residual current sensitivity – UNIVERSAL
AC pure sine wave residual current, 50/60 Hz
Sine wave and pulsating DC current, 50/60 Hz
B: AC + A + smooth DC + high frequency (1 kHz)
2. Standards
IEC/EN 61009-1 Basic standards for AC and A-type RCBOs
Additional requirements of IEC/EN 62423 for type B
3. Typical Applications
Protection against faults (protection against indirect contact with live parts
Supplementary protection (protection in case of direct contact with live parts, I∆n≤30 mA)
Fire protection (for locations exposed to fire hazards, I∆n ≤ 300 mA)
4. Which of the following are sensitive to smooth DC residual currents?
Photovoltaic systems, AC side.
Charging stations for electric vehicles.
Variable-speed machine tools.
UPS, computer data centers.
Elevator controls.
Cranes of all types.
Electronic equipment on construction sites.
Test setups in laboratories.
General installations where smooth DC residual currents can be expected.
The maximum current of the EKL5-63 B RCBO can reach 63 amperes, and three trip current options—30 mA, 100 mA, and 300 mA—are available to meet the needs of various scenarios.
