The Schneider Electric iC60N is a high-performance miniature circuit breaker designed for electrical distribution in commercial and industrial environments. This 2P device combines thermal-magnetic protection with a C curve response, making it suitable for circuits with moderate inrush currents. Additionally, the iC60N 2P C40 offers a 6 kA breaking capacity according to IEC 60898-1 and 10 kA under IEC 60947-2 at 400 V AC.
The iC60N 2P C40 operates with a rated current of 40 A and a magnetic trip threshold of 8×In ± 20%. Furthermore, its thermal-magnetic trip unit responds to both overload and short-circuit conditions. The rated operational voltage reaches 400 V AC for phase-to-phase applications, with DC capability up to 125 V. Meanwhile, the service breaking capacity of 7.5 kA at 380–415 V AC ensures reliable performance under fault conditions.
For coordination purposes, this iC60N breaker supports cascading with upstream devices. Specifically, proper selection of upstream protection allows the iC60N 2P C40 to achieve enhanced short-circuit withstand ratings. Therefore, system designers can optimize protection schemes without oversizing downstream components.
This miniature circuit breaker features a compact form factor of 85 mm × 36 mm × 78.5 mm. Besides, the device weighs approximately 0.25 kg, facilitating straightforward handling during installation. The operating temperature range spans -35°C to +70°C, while storage temperature reaches -40°C to +85°C.
Moreover, the iC60N provides IP20 protection for the device itself and IP40 when mounted in an enclosure. The mechanical endurance reaches 20,000 cycles, and electrical durability is rated at 10,000 cycles. Additionally, the product complies with both EN/IEC 60898-1 and EN/IEC 60947-2 standards.
First, ensure the power supply is completely disconnected before beginning installation. Next, snap the iC60N 2P C40 onto a standard 35 mm DIN rail. The device accepts rigid cables from 1 to 35 mm² and flexible conductors from 1 to 25 mm². For instance, tighten terminal screws to the specified torque of 3.5 N·m to guarantee secure connections.
Additionally, the breaker supports top or bottom connection orientation. Combined busbar compatibility allows for efficient multi-pole installation. However, always verify proper polarity when using DC applications.
