The Schneider Electric Acti9 iC60N A9F79206 circuit breaker is a modular automatic breaker with 2 protected poles, 6 A and C curve, designed to protect low-voltage electrical circuits against overloads and short circuits. It offers a rated breaking capacity Icn of 6 kA at 400 V AC according to IEC/EN 60898-1 and an ultimate breaking capacity Icu of 10 kA at 380-415 V AC according to IEC/EN 60947-2. It incorporates VisiTrip and VisiSafe technologies, class 3 current limiting and suitability for isolation, delivering the right performance for residential, commercial, tertiary and professional distribution boards.
Reference A9F79206 belongs to Schneider Electric's Acti9 iC60N range and uses a thermal-magnetic trip unit. Its bipolar format takes up only two 18 mm modules and allows both poles of the circuit to be protected simultaneously. In addition, it can be complemented with Acti9 auxiliaries, monitoring systems and compatible Vigi residual current blocks when the installation requires additional functions.
The Schneider Electric A9F79206 has 2 poles and 2 protected poles. Both poles are protected against overcurrents and open together when the device trips.
The Acti9 iC60N combines two complementary protection principles:
This combination allows the A9F79206 to be used as overcurrent protection in circuits whose current and conductor cross-section are compatible with its 6 A rating.
Reference A9F79206 incorporates a C trip curve. Schneider Electric specifies a magnetic threshold of 8 × In ±20 %.
The C curve allows certain transient inrush peaks to be withstood without immediate magnetic tripping and is commonly used in distribution circuits with loads that present moderate starting currents.
It may be suitable, subject to installation calculations, for applications such as:
In accordance with IEC/EN 60898-1, Schneider Electric specifies for the A9F79206 a rated breaking capacity Icn of 6,000 A at 400 V AC and 50/60 Hz.
The service breaking capacity according to the same standard is also:
The value of 6 kA is therefore the one corresponding to the nominal short-circuit capacity according to IEC/EN 60898-1.
The 10 kA value commonly included in the commercial designation corresponds to the ultimate breaking capacity Icu at 380-415 V AC according to IEC/EN 60947-2.
Schneider Electric specifies the following Icu values in AC:
Therefore, the values 6 kA and 10 kA are both correct, but they correspond to different standards and test conditions.
According to IEC/EN 60947-2, the main service breaking capacity values are:
The required breaking capacity must be checked against the maximum prospective short-circuit current at the point where the circuit breaker will be installed.
The A9F79206 is also specified for certain direct current applications. Schneider Electric indicates an Icu of 10 kA up to 125 V DC, within the connection conditions established by the manufacturer.
When used in direct current, the maximum voltage, polarity and connection scheme specifically indicated for the Acti9 iC60 range must be respected.
The circuit breaker has class 3 current limiting according to IEC/EN 60898-1.
This capability makes it possible to limit peak current and the energy flowing through the circuit during a short circuit, reducing the thermal and electrodynamic stresses borne by downstream conductors and devices.
The VisiTrip system makes it easy to quickly identify a circuit that has tripped due to an electrical fault.
This local indication is especially useful in panels with several circuit breakers, as it helps locate the affected outgoing circuit and reduces the time needed for diagnosis.
The VisiSafe technology allows the safe open position of the contacts to be visually checked, providing greater clarity during circuit isolation and maintenance operations.
The A9F79206 is also declared suitable for isolation according to IEC/EN 60898-1 and IEC/EN 60947-2.
Schneider Electric expressly specifies its suitability for industrial isolation according to IEC/EN 60947-2, a feature especially relevant in professional panels and applications where the circuit breaker forms part of the circuit isolation procedure.
The Acti9 iC60N A9F79206 is designed for fixed installation on a DIN rail, making it easy to integrate with other Schneider Electric modular devices.
The circuit breaker terminals allow supply from the top or bottom, providing flexibility during panel wiring.
The device can also be integrated with compatible Acti9 distribution combs.
The Schneider Electric iC60N can be complemented with different auxiliary devices from the Acti9 platform to expand panel functions.
Available options include:
Exact compatibility must be checked according to the accessory reference and the installation configuration.
The A9F79206 is an MCB circuit breaker. Its function is to protect against overloads and short circuits, but it does not include residual current protection as standard.
When it is necessary to detect earth leakage currents, it can be combined with a compatible Vigi residual current block or installed together with another correctly selected residual current device.
The Acti9 iC60N range is designed for a long service life:
These features make the device suitable for panels subject to regular switching, disconnection, testing and maintenance operations.
The Schneider Electric A9F79206 has:
As a modular device, it must be installed inside an enclosure that provides the degree of protection required by the operating environment.
Its 6 A rating, bipolar configuration and C curve make it suitable as protection for multiple low-current circuits, provided the electrical characteristics of the installation are compatible.
The Schneider Electric Acti9 iC60N A9F79206 combines two protected poles, a 6 A rating and C curve with an interrupting capacity of 6 kA Icn at 400 V according to IEC/EN 60898-1 and 10 kA Icu at 380-415 V according to IEC/EN 60947-2.
VisiTrip and VisiSafe technologies make fault identification and maintenance operations easier, while its two-module format and compatibility with auxiliaries and Vigi blocks make it possible to create compact, expandable protection panels.
Important: the A9F79206 does not include residual current protection. Before installation, the circuit design current, conductor cross-section, trip curve, prospective short-circuit current and required breaking capacity must be checked. When protection against earth leakage is required, it must be supplemented with a suitable residual current device.
