Acti9 RED 2P 40A 30 mA Type A self-resetting differential

The Schneider Electric Acti9 RED 2P 40A 30mA Type A self-resetting differential, 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 minimizing the downtime of the electrical supply during transient faults is desired. 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 against fire risks arising from insulation failures. With a sensitivity of 30mA, this differential ensures that any dangerous current leakage to ground is quickly detected, disconnecting the circuit before it can pose a danger. This feature makes it a perfect solution for protecting people and property in residential and commercial electrical systems.

Automatic restart for greater continuity:

One of the main features that distinguishes the Acti9 RED from other differential devices is its ability for automatic reconnection. After disconnecting the circuit due to a ground fault, the device monitors to ensure that conditions are safe before reconnecting the supply. This 4-cycle reconnection process ensures that power is restored automatically without the need for manual intervention, minimizing downtime and ensuring continuity of electrical service in the event of transient faults. This function is especially useful in places where a prolonged supply interruption could cause inconvenience or losses, such as in 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 for easy installation in existing or new systems without requiring significant modifications. Its modular design not only facilitates installation but also optimizes the use of available space in electrical panels where capacity is limited.

The differential switch is designed with 2 poles (2P) and is installed with the neutral on the left side, 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 grounding systems:

The Acti9 RED is compatible with TT and TN-S grounding systems, making it suitable for most residential and commercial installations. These systems are the most commonly used in domestic applications, ensuring that the device operates 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
• Grounding system: TT and TN-S
• Nominal breaking capacity (Im/IΔm): 630A
• Assigned conditional current (Inc/IΔc): 6 kA
• Mechanical resistance: 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 manufacturing and operation of residual current devices. Additionally, it is certified with CE and EAC approvals, ensuring that the device meets European and other international market regulations for use in safe and efficient electrical installations.

Residential and commercial applications:

This differential switch 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 continuity of electrical supply, even after minor transient faults. It is also suitable for small commercial applications or electrical systems where downtime could result in significant losses or inconveniences.

Durability and robustness:

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