Schneider Electric A9Z21463 RCD IID 4-pole 63 A 30 mA Type A content_copy

The Acti9 iID residual current circuit breaker from Schneider Electric is a 4-pole RCD from the Acti9 series, designed for use in electrical distributions in industrial and building management applications. It provides protection against electric shock from direct contact by detecting fault currents from 30 mA and is designed for protection class Type A, making it suitable for detecting pulsating and direct current fault currents. The switch is designed for an operating voltage of 400 to 415 V AC at a frequency of 50/60 Hz and features a rated current of 63 A. Tripping occurs instantaneously upon reaching the earth fault sensitivity of 30 mA, ensuring rapid disconnection in the event of dangerous fault currents.

Applications

The circuit breaker is intended for use in distributions where additional protection against electric shock is required, particularly in areas with increased risk of contact. It is suitable for applications requiring protection class Type A, such as in households, office buildings, industrial plants, or construction power distributors. Compliance with standards EN/IEC 61008-1 and EN/IEC 61008-2-1, along with VDE certification, confirms conformity with applicable safety requirements.

Functions and Equipment in Detail

The switch features a mechanical front-mounted fault indication (VisiTrip), which indicates tripping due to overload or short circuit. Additionally, a secure contact position indicator (VisiSafe) is integrated, which signals voltage-free conditions on the output side when green. A test button enables regular functional testing. Double connection terminals on the front and rear allow for two-sided connection of cables or phase bars, ensuring flexible installation. Mounting is tool-free on the left side of the device onto a 35 mm DIN rail.

Technology Explained Simply

The residual current tripping technology is voltage-independent, meaning the switch operates reliably even during voltage fluctuations or phase-shifted currents. The rated breaking capacity is 1500 A, and the conditional rated short-circuit current is 10 kA, highlighting the device’s ability to safely interrupt short-circuit currents. The insulation voltage (Ui) is 500 V AC, and the impulse voltage withstand (Uimp) is specified at 6 kV, ensuring the device’s electrical strength in transient overvoltage situations. The mechanical life is 20,000 cycles, and the electrical life is 15,000 cycles, indicating high operational reliability.

Compatibility and Accessories

The switch can be extended with optional auxiliary modules, including undervoltage release (iMN), overvoltage release (iMSU), load current release (iMX), auxiliary switch for status indication (iOF), and fault indication switch (iSD). These modules can be mounted in series on the device to enable additional functions such as automatic disconnection during voltage dips or status transmission. Compatible accessories include, for example, load current release iMX+OF, installation contactors iCT, rotary drives iC60, phase bar modules, and feed terminals, which facilitate integration into existing distributions.

Mounting and Installation

Mounting is on a 35 mm DIN rail, with the device being snap-on and allowing tool-free mounting on the left side. The terminals are equipped with double terminals suitable for rigid cable (up to 35 mm² on the front, up to 25 mm² on the rear) and flexible conductors (up to 25 mm² on the front, up to 16 mm² on the rear). The wire stripping length is 14 mm, and the tightening torque for the terminals is specified at 3.5 Nm. Locking options include the possibility of mounting a padlock, enabling secure disconnection.

Operational Advantages

The circuit breaker offers high operational reliability through the combination of fast tripping for fault currents, visual status indication, and long service life. The front-accessible mounting elements facilitate removal of the device when a phase bar is installed. The white color (RAL 9003) ensures uniform visual design in distributions. The operating temperature ranges from -25 °C to 60 °C, enabling broad application in various environments. The protection rating IP20 (in the device) and IP20 (in the modular enclosure) complies with IEC 60529 requirements, ensuring protection against contact and contamination. Electromagnetic compatibility is specified for impulse surges of 8/20 µs with 250 A, ensuring robustness against transient disturbances.
