Product Introduction
The Schneider Electric Acti9 iC60N 3P C63 is a high-performance miniature circuit breaker designed to protect electrical circuits against overloads and short circuits. As part of the well-known Acti9 range, this iC60N 3P C63 model blends advanced protection technology with simple installation, making it a strong choice for industrial automation professionals.
Technical Specifications
This 3-pole circuit breaker carries a 63 A rated current and uses a C-curve thermal-magnetic trip unit. Specifically, the magnetic trip operates between 8×In ±20%, which suits inductive loads with moderate inrush currents. Meanwhile, the 6 kA breaking capacity at 400V AC ensures solid short-circuit protection under the IEC 60898-1 standard. Additionally, the device complies with IEC 60947-2 for industrial isolation, offering a 10 kA Icu rating at 380-415V AC.
Mechanical and Environmental Parameters
The breaker mounts securely on a standard 35 mm DIN rail, with dimensions of 82 × 54 × 78.5 mm. It operates reliably within a temperature range of -35 to 70 °C. Furthermore, the mechanical life reaches 20,000 cycles, while the electrical life is rated at 10,000 cycles, ensuring long-term durability in demanding environments.
Installation Guide
Installation is straightforward thanks to the clip-on mounting mechanism. First, ensure the DIN rail is properly secured. Next, snap the iC60N 3P C63 onto the rail until it clicks into place. Then, strip the wire insulation to 14 mm for terminal connections. The terminals accept rigid cables from 1 to 35 mm² and flexible cables from 1 to 25 mm². Finally, tighten the terminal screws securely to complete the wiring process.

FAQ
Q1: What is the difference between Icn and Icu ratings?
The Icn rating represents the short-circuit capacity per IEC 60898-1, while Icu indicates the ultimate breaking capacity under IEC 60947-2. For this model, Icn is 6 kA, whereas Icu reaches 10 kA at 400V AC.
Q2: Can this breaker handle motor starting currents?
Yes. The C-curve characteristic allows the breaker to tolerate brief inrush currents common with inductive loads. Specifically, the magnetic trip threshold sits between 6.4× and 9.6× the rated current.
Q3: What wire sizes does the terminal accept?
The terminals accommodate rigid cables from 1 to 35 mm² and flexible cables from 1 to 25 mm². This wide range supports various industrial wiring configurations.
Q4: Is this device suitable for DC applications?
Yes. The iC60N 3P C63 supports DC networks up to 180 V DC, with a breaking capacity of 10 kA under IEC 60947-2.
Q5: How do I know if the breaker has tripped?
A mechanical indicator (VisiTrip) on the front face shows a red flag when the breaker trips due to a fault. This visual feedback allows quick identification of faulty circuits.
