The Schneider Electric Quick Vigi iC60 A9Q31240 residual current block is an additional module with 2 poles, 40 A rating and 30 mA sensitivity, designed to add residual current protection to a compatible Acti9 iC60 miniature circuit breaker. It uses super-immunised type A-SI technology, features instantaneous tripping and operates at a rated voltage of 230-240 V AC at 50/60 Hz, offering a compact solution for protecting single-phase circuits against earth leakage currents.
Its Quick Vigi system makes it easy to connect mechanically and electrically to the compatible circuit breaker, creating a protection assembly that combines the overload and short-circuit protection functions of the iC60 with the residual current protection provided by the Vigi block. This configuration is especially useful in electrical panels where a modular, reliable solution with greater immunity to nuisance tripping is required.
The Schneider Electric A9Q31240 is designed for 2-pole configurations and has a rated current of 40 A.
It must be combined with a compatible and correctly sized circuit breaker. The residual current block does not, by itself, replace the miniature circuit breaker protection against overloads and short circuits.
The rated residual current sensitivity is 30 mA, a high-sensitivity level used to provide additional protection against certain risks associated with electric shock and leakage currents, in accordance with installation conditions and applicable regulations.
The device monitors circuit current balance and trips the assembly when it detects a residual current that reaches the specified tripping conditions.
One of the main features of the A9Q31240 is its type A-SI residual current protection. SI technology, known as Super Immunised by Schneider Electric, provides greater immunity against certain electrical disturbances that can cause nuisance tripping in conventional residual current devices.
As a type A device, it can detect sinusoidal alternating residual currents and pulsating direct residual currents. This is especially relevant in modern installations that include power electronics and loads with rectifiers or electronic power supplies.
A-SI technology is particularly suitable for installations with electronics that may generate disturbances, harmonics or transient currents.
It can be especially useful in circuits with LED lighting, computer equipment, switched-mode power supplies, automation systems, appliances with electronics, HVAC equipment and other loads compatible with type A residual current protection.
Schneider Electric specifies for this version a withstand to impulse currents of up to 3 kA with 8/20 µs wave, helping to reduce unwanted tripping in the presence of certain electrical transients.
The Quick Vigi A9Q31240 features instantaneous residual current protection. This means it does not include an intentional time delay like that used in selective residual current devices.
When the residual current reaches the conditions set for operation, the mechanism disconnects the assembly immediately within the times required by the standard.
Schneider Electric specifies a voltage-independent residual current tripping technology.
This feature allows the basic residual current detection function to operate without relying on an external auxiliary electronic power supply to trip.
The A9Q31240 is designed for AC circuits with the following characteristics:
The name Quick Vigi refers to the system designed by Schneider Electric to simplify the combination of the residual current block with the compatible miniature circuit breaker.
The electrical connection to the circuit breaker is made using a plug-in system, simplifying assembly and reducing the need for additional wiring between both devices.
This solution helps save installation time and provides a compact connection between the miniature circuit breaker and residual current functions.
The A9Q31240 belongs to the Acti9 Vigi iC60 family and is designed to be combined with compatible Acti9 iC60 circuit breakers.
Once coupled, the circuit breaker provides overload and short-circuit protection, while the Vigi block adds earth leakage current detection.
Before assembling the unit, the exact pole configuration, rating and reference of the circuit breaker used must be checked.
Schneider Electric includes a red mechanical indicator on the front face that shows tripping associated with a fault.
This signalling makes diagnosis inside the electrical panel easier and allows rapid identification of a residual current protection operation.
The assembly is designed to meet the isolation requirements established by EN/IEC 61009-1 and EN/IEC 61009-2-1 standards when used in accordance with Schneider Electric’s specified conditions.
This feature allows it to be integrated into protection and isolation systems for circuits within low-voltage electrical panels.
The Quick Vigi iC60 is designed for clip-on mounting on a DIN rail, making installation alongside the rest of the Acti9 devices easier.
The block occupies 4 x 9 mm modules, equivalent to a width of 36 mm or 2 standard 18 mm modules.
Its compact format makes it possible to add residual current protection to an iC60 circuit breaker without using a wider standalone residual current device.
The lower tunnel terminals provide a robust connection for conductors.
The Quick Vigi design allows compatible distribution systems to be used at the lower part of the assembly.
This feature makes it easier to create neat and compact panels using suitable Acti9 distribution combs for the selected configuration.
The device has an IP20 protection rating as an individual component.
Once correctly installed inside a suitable modular enclosure, the assembly can achieve a protection rating of up to IP40, depending on the panel characteristics.
The Schneider Electric A9Q31240 is designed to operate over a wide temperature range:
These specifications allow it to be used in a wide variety of indoor electrical panels within the environmental conditions indicated by the manufacturer.
The Quick Vigi iC60 residual current block can be used in single-phase installations where 30 mA residual current protection needs to be added to a compatible iC60 circuit breaker.
Applications include residential panels, offices, retail premises, tertiary installations, circuits with electronics, LED lighting, computer equipment and other lines where high residual current sensitivity with greater immunity to disturbances is required.
The Schneider Electric Quick Vigi iC60 A9Q31240 allows high-sensitivity residual current protection to be added to a compatible Acti9 iC60 miniature circuit breaker. Its 40 A rating, 30 mA sensitivity and A-SI technology provide a solution especially suited to installations with electronic equipment where nuisance tripping needs to be reduced.
Its plug-in connection system, mechanical trip indicator, 36 mm format and DIN rail compatibility make it easy to assemble compact, professional units inside distribution electrical panels.
Important: the A9Q31240 is an additional residual current block and does not function as an independent miniature circuit breaker. On its own, it does not provide overload or short-circuit protection; it must be installed together with a compatible and correctly sized Acti9 iC60 circuit breaker.
