Specific use: Solar and charging stations

This 63A circuit breaker is particularly suitable for:

  • AC output protection: Essential for single-phase photovoltaic inverters from 6kW to 12kW (e.g. Deye, Sofar, Huawei).
  • Charging infrastructure (IRVE): Securing 7.4kW and 11kW charging stations.
  • Power panels: General protection for outbuildings or heat pumps (HP).

Expert advice: The Schneider Acti9 range is renowned for its durability. By choosing the iC60a model, you are ensuring maximum longevity for your sensitive components, such as hybrid inverters.





Certified compatibility with leading solar manufacturers

The Schneider Acti9 iC60a 63A circuit breaker has been selected for its perfect compatibility with the most efficient inverters on the market, available on our website:

  • Deye Hybrid Inverters: Ideal protection for single-phase models from 5kW to 8kW (AC Load or Grid output).
  • WKS range (Evo, Circle, Isolar): Ensures a clean and safe cut-off for high-power off-grid inverters.
  • Sofar Solar inverters: Recommended for securing the grid injection of your single-phase string inverters.
  • Storage systems: Suitable for protecting battery circuits coupled with high-intensity chargers.

Note: Its 63A rating allows it to absorb current peaks without tripping, while ensuring immediate thermal protection.





Installation and maintenance

Installation is simple on a 35 mm DIN rail. Thanks to its ergonomic design, replacing or adding modules to your electrical panel is quick and easy. For optimal safety, check that the terminals are tightened to the recommended torque (3.5 Nm for this rating).

Electrical safety: The installation must comply with current standards (NF C 15-100 or RGIE). Always switch off the power before handling.





FAQ - Schneider Acti9 iC60a 63A circuit breaker

1. Why is this circuit breaker recommended for solar and EV charging stations? +
With a 63A rating and a C curve, this model is ideal for handling the constant load currents of powerful photovoltaic inverters (6kW to 12kW) and electric vehicle charging stations. Its industrial design ensures that it does not overheat during prolonged charging cycles.
2. What are the VisiSafe and VisiTrip safety features? +
VisiSafe ensures that the downstream circuit is truly de-energised when the lever is lowered, thus making any maintenance work safe. VisiTrip is a visual indicator (red light) that allows you to immediately identify which circuit breaker has tripped due to an electrical fault, facilitating rapid diagnosis of your installation.
3. How important is the 6 kA breaking capacity? +
The 6000A (6 kA) breaking capacity indicates the circuit breaker's ability to interrupt a major short circuit without being destroyed. For a solar or power installation, this ensures that the device will effectively protect your hybrid inverter or sensitive equipment from severe network failures.
4. What cable cross-sections can be connected to this model? +
This circuit breaker is equipped with wide terminals that can accommodate cables up to 50 mm² for rigid wire and 35 mm² for flexible wire. It is crucial to use a tightening torque of 3.5 Nm to ensure a perfect connection and avoid any risk of electric arcing due to poor fastening.
