## Summary description

Schneider Electric Acti9 residual current circuit breaker (RCCB) 4-pole, 40 A rated current, 0.03 A (30 mA) residual current sensitivity, Type B-EV. Designed to detect AC, pulsating DC and smooth DC residual currents including EV charging signatures. Used for personnel protection and earth-fault detection in residential, commercial and EV charging installations.

## Long description

Schneider Electric Acti9 residual current circuit breaker 4P 40A 0.03A Type B-EV iID-40-4-30-B-EV is a four-pole residual current device designed to detect and interrupt dangerous earth-fault currents in modern electrical installations. With a rated current of 40 A and residual current sensitivity of 30 mA, this device offers protection for people against electric shock and contributes to fire prevention. The Type B-EV characteristic extends detection capability to alternating currents, pulsating DC and smooth DC residual currents, including waveforms typical of electric vehicle (EV) charging equipment.
Advantages
The Acti9 4P 40A 0.03A Type B-EV provides reliable, compact protection that combines fast residual current detection with immunity to nuisance tripping from common installation disturbances. Its B-EV characteristic makes it suitable for circuits that include power electronics and EV chargers by recognising smooth DC residual currents as well as AC and pulsating DC, ensuring consistent operation in mixed-load environments. The device is intended for DIN-rail mounting and integrates with standard distribution boards used in residential and commercial applications.
Suitable for (tasks / use cases)
Protection of circuits feeding electric vehicle charging points where DC leakage can occur
Residential and small commercial distribution boards requiring personnel protection from earth faults
Installations with power electronic loads such as variable speed drives, inverters and photovoltaic inverters
Applications where a 4-pole device is needed to simultaneously protect three phases and neutral
When it may not be suitable
This residual current device is not intended for use as a main overcurrent protector; it provides earth-fault detection but does not replace appropriate overload or short-circuit protection devices. In installations with unusual or proprietary DC fault signatures not covered by Type B-EV specifications, separate verification is recommended to ensure compatibility. It is also not suitable where a different sensitivity or pole count is required.
Key specifications
Poles: 4-pole (three phases + neutral)
Rated current: 40 A
Residual current sensitivity: 0.03 A (30 mA)
Tripping characteristic: Type B-EV (detects AC, pulsating DC and smooth DC including EV charging signatures)
Mounting: DIN-rail compatible
Primary function: personnel protection and earth-fault detection
How to use
Install the device in the distribution board on a DIN rail following local electrical codes and the manufacturer’s mounting instructions. Connect the incoming supply and outgoing load conductors to the appropriate terminals for the three phases and neutral. Ensure that downstream overcurrent protection devices are installed where required. Test the trip function after installation and periodically during service using recommended test procedures to confirm correct operation and continuity of protective functions.
What to consider before purchase
Confirm that a 40 A rated device with 30 mA sensitivity and Type B-EV characteristic matches the circuit requirements
Verify physical space and DIN-rail compatibility within the intended distribution board
Ensure complementary overcurrent protection (breakers/fuses) is specified separately where needed
Check compatibility with connected equipment, particularly EV chargers and power electronic devices
Usage recommendations
For reliable protection, use this Type B-EV residual current breaker where EV charging or other DC-generating equipment is present. Combine with correctly rated overcurrent protection and perform regular functional tests to maintain safety and compliance with local regulations.
