Introduction: The Evolution of Circuit Protection
Three decades ago, plant engineers sized protection by trial and error. A fault would trip an entire panel, and restarting a production line could take hours. Today, compact modular devices isolate faults at the branch level. The Schneider iC60N 2P C25 continues that evolution. It is a two-pole miniature circuit breaker from the Acti9 iC60 series, rated 25 A with a C trip curve. This device protects control panels, distribution boards, and machinery circuits from overload and short circuit. Because the Acti9 range remains in active production, you can standardize new builds and retrofit aging panels with the same footprint. SpareTechPLC supplies this breaker for buyers who need a reliable, traceable replacement.
Technical Specifications That Matter
The iC60N 2P C25 carries a 25 A rated current across two poles. A C-curve thermal-magnetic trip unit handles inrush currents up to 8×In ±20%, which suits motors, transformers, and capacitive loads. The 6 kA breaking capacity at 230/400 V means the breaker safely interrupts fault currents in most commercial and light industrial installations. Rated voltage reaches 400 V AC and 125 V DC, giving you flexibility across AC distribution and DC control circuits. The device meets EN/IEC 60898-1 and EN/IEC 60947-2 standards. Operating temperature spans -35 to 70 °C, so it performs in cold storage rooms and hot process areas alike.

Where the iC60N 2P C25 Fits
Industrial Control Panels
Machine builders use the 25 A rating to protect feeder circuits for contactors, relays, and small drives. The C-curve tolerates brief current spikes when a motor starts, preventing nuisance trips that stop production.
Commercial Distribution Boards
Facility managers specify this breaker for lighting and power sub-circuits. The 6 kA breaking capacity covers typical panelboard fault levels, and the 2-pole configuration protects both live and neutral conductors.
Replacement and Upgrade Projects
If you maintain legacy equipment, the iC60N 2P C25 offers a direct upgrade path. Its 35 mm DIN rail mount and 36 mm width fit standard enclosures. The active lifecycle status means spare units remain available, reducing downtime risk during planned maintenance.
Installation and Setup
Mount the breaker on a 35 mm DIN rail inside a suitable enclosure. Verify the rated voltage and current match your circuit before installation. Tighten terminals to the torque specified by Schneider Electric. Do not exceed the 400 V AC or 125 V DC rating. For DC applications, confirm polarity and connection diagrams from the manufacturer. Always follow local electrical codes and lockout procedures during installation.
Maintenance and Reliability
The iC60N 2P C25 delivers 20,000 mechanical cycles and 10,000 electrical cycles. Inspect periodically for signs of overheating, discoloration, or loose terminals. Test the trip function during scheduled shutdowns. Keep the operating environment within -35 to 70 °C. Dust and moisture can affect performance, so ensure enclosure seals remain intact. Because the Acti9 range is active, you can plan long-term maintenance with confidence.
Compatibility and Integration
This breaker integrates with standard 35 mm DIN rail systems. It works alongside Schneider Acti9 accessories and similar modular devices. The 2-pole design suits single-phase and DC circuits. Verify coordination with upstream protection to maintain selective tripping. The 6 kA breaking capacity matches typical industrial control panel requirements.
Selection Guide
Before ordering, confirm your system voltage does not exceed 400 V AC or 125 V DC. Check that the 25 A rating and C-curve match your load profile. Verify the 2-pole configuration fits your wiring scheme. The 85 × 36 × 78.5 mm dimensions require adequate panel space. SpareTechPLC stocks the iC60N 2P C25 and can help you verify compatibility. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
