Product Overview
Downtime on a 400V distribution board often traces back to a breaker that no longer trips cleanly. The iC60N 2P C63 from Schneider Electric solves that problem with a proven thermal-magnetic design in the Acti9 iC60 series. This two-pole miniature circuit breaker carries a 63A rating and a C trip curve, so it handles motor inrush and transformer surges without nuisance tripping. Maintenance engineers choose it because it protects two phases at once and installs on standard 35 mm DIN rail in minutes.
Technical Specifications
Current Rating and Trip Curve
The 63A rated current suits feeder and sub-distribution circuits that draw heavy continuous loads. The C curve trips magnetically at 8×In ±20%, which means it tolerates short inrush currents while still clearing faults fast. For a maintenance team, that balance reduces callouts caused by false trips on equipment start-up.
Breaking Capacity and Voltage
The 6 kA breaking capacity at 230/400V (IEC 60898-1) covers most commercial and light industrial panels. Rated voltage reaches 400V AC and 125V DC, giving you flexibility for AC distribution and certain DC control circuits. Always confirm the actual system voltage before replacement.
Physical and Lifecycle Data
Each pole measures 85 × 36 × 78.5 mm and weighs 0.25 kg, so a two-pole unit fits compact enclosures. Mechanical life reaches 20,000 cycles and electrical life 10,000 cycles. That endurance keeps service intervals predictable and lowers total cost of ownership.
Replacement and Upgrade Guide
Angle D fits this product well. When an older breaker fails or nuisance-trips, the iC60N 2P C63 is a direct-fit replacement on 35 mm DIN rail. Match the pole count, current rating, and trip curve before you swap. Check the busbar alignment and terminal torque during installation. Because the Acti9 iC60 range remains active in production, spare units stay available, which shortens unplanned downtime. Keep one spare on the shelf for critical feeders and you avoid emergency sourcing delays.
Installation and Setup
Mount the device on a 35 mm DIN rail inside a compatible enclosure. Confirm the supply is isolated before you work. Land incoming and outgoing conductors on the correct terminals and tighten to the manufacturer’s specification. Verify the C-curve marking matches the load profile. After energizing, test the trip function and record the result in your maintenance log. Operating temperature spans -35 to 70 °C, so most plant environments need no derating.
Maintenance and Reliability
Inspect the breaker during scheduled panel maintenance. Look for discoloration, loose terminals, or signs of overheating. Exercise the toggle periodically to confirm free movement. The 20,000-cycle mechanical life supports long service between replacements. Keep the enclosure free of dust and moisture to protect insulation. If a breaker trips repeatedly, investigate the load rather than resetting it blindly. A failed device should be replaced, not repaired.
Compatibility and Integration
This breaker follows EN/IEC 60898-1 and EN/IEC 60947-2 standards, so it integrates with standard distribution boards and DIN rail systems. It works alongside other Acti9 iC60 devices for consistent panel layouts. Verify busbar compatibility and terminal capacity with your enclosure supplier before ordering.
Selection Guide
Before buying, confirm these points: two poles, 63A rating, C curve, and 6 kA breaking capacity. Check the system voltage against the 400V AC or 125V DC rating. Measure available DIN rail space using the 36 mm width. SpareTechPLC stocks genuine Schneider components and can confirm availability.

FAQs
Q: Can I use this breaker for motor circuits?
A: The C curve tolerates inrush, but verify the motor’s starting current and protection coordination before use.
Q: What is the difference between mechanical and electrical life?
A: Mechanical life covers 20,000 toggle operations without load. Electrical life covers 10,000 operations under load.
Q: Does it fit standard DIN rail?
A: Yes, it mounts on 35 mm DIN rail, the common standard in industrial panels.
Q: Is this model still in production?
A: Yes, the Acti9 iC60 range is active. Confirm current stock with SpareTechPLC.
