Auto-reclosing Differential Acti9 RED 2P 40A 30 mA Type A

The Schneider Electric Acti9 RED 2P 40A 30mA Type A Self-resetting RCD, reference A9CR1240, is an advanced device designed to provide comprehensive protection in residential electrical systems. This residual current circuit breaker (RCCB) not only protects against electric shocks but also features an automatic reconnection function, making it ideal for applications where minimising downtime due to transient faults is crucial. Compact and highly efficient, the Acti9 RED occupies only 3 module spaces, making it a flexible option for installations with space constraints.

Protection against shocks and enhanced safety:

The Acti9 RED protects against electric shocks from direct and indirect contact as well as fire risks arising from insulation failures. With a sensitivity of 30mA, this RCD ensures any dangerous earth leakage current is quickly detected, disconnecting the circuit before it poses a hazard. This feature makes it a perfect solution for protecting people and property in domestic and commercial electrical systems.

Automatic reset for greater continuity:

One of the main features that distinguishes the Acti9 RED from other RCDs is its automatic reconnection capability. After disconnecting the circuit due to earth leakage, the device monitors to ensure conditions are safe before reconnecting the supply. This 4-cycle reconnection process ensures the power is restored automatically without manual intervention, minimising downtime and ensuring electrical service continuity in the event of transient faults. This function is particularly useful in locations where prolonged power interruption could cause inconvenience or loss, such as homes or small businesses.

Compact design and easy installation:

The Acti9 RED is notably compact, occupying only 3 module spaces in the electrical panel. This allows it to be easily installed in existing or new systems without requiring significant modifications. Its modular design not only facilitates installation but also optimises the use of available space in electrical panels where capacity is limited.

The RCD is designed with 2 poles (2P) and is installed with the neutral on the left, ensuring compatibility with most residential electrical panel configurations. This pole design ensures that both the phase and neutral are protected, providing an additional layer of safety.

Compatible with TT and TN-S earthing systems:

The Acti9 RED is compatible with TT and TN-S earthing systems, making it suitable for most residential and commercial installations. These systems are the most commonly used in domestic applications, ensuring the device functions correctly in a wide range of electrical environments.

Key technical specifications:

• Rated current (In): 40 A
• Earth leakage sensitivity: 30 mA
• Number of poles: 2P (phase and neutral)
• Network voltage: AC
• Earthing system: TT and TN-S
• Rated breaking and making capacity (Im/IΔm): 630A
• Conditional rated current (Inc/IΔc): 6 kA
• Mechanical endurance: Up to 4000 cycles

Regulatory compliance and guaranteed safety:

The Acti9 RED complies with the highest safety standards, including the EN 60557 standard, which regulates the manufacture and operation of RCDs. Additionally, it is certified with CE and EAC approvals, ensuring that the device meets European and other international market regulations for safe and efficient electrical installations.

Residential and commercial applications:

This RCD is ideal for residential applications, where electrical safety is a priority. Its self-resetting capability makes it a perfect solution for homes that need to maintain electrical supply continuity, even after minor transient faults. It is also suitable for small commercial applications or electrical systems where disconnection time can result in significant losses or inconvenience.

Durability and robustness:

The Acti9 RED is designed to offer high mechanical resistance, with the ability to withstand up to 4000 operation cycles. This durability ensures the device operates reliably over time, providing continuous protection without failures. The RCD has a rated closing and breaking capacity (Im/IΔm) of 630A, ensuring its ability to disconnect the circuit in emergency situations without compromising its integrity.
