Product Overview
Downtime in a control panel often starts with a single unprotected circuit. The iC60N 1P C20 from Schneider Electric solves that problem with dependable 20A single-pole protection in a compact DIN rail package. This miniature circuit breaker belongs to the Acti9 iC60 series, a range trusted across industrial and commercial installations.
With a C-curve trip profile, this device handles the inrush currents of small motors and transformers without nuisance tripping. It combines thermal and magnetic protection in one 18 mm wide module, so panel space stays efficient.
Key Technical Specifications
The iC60N 1P C20 delivers performance that suits demanding low-voltage distribution. Its 6 kA breaking capacity at 230/400V means it safely interrupts fault currents up to that level. The rated voltage covers 230/400V AC and 125V DC applications.
A C-curve thermal-magnetic trip unit trips magnetically at 8×In ±20%. This makes the breaker a strong fit for inductive loads. The operating temperature range of -35 to 70 °C supports use in harsh plant environments.

Where This Breaker Performs Best
Industrial Control Panels
Machine builders use the iC60N 1P C20 to protect control transformers and small drives. The C-curve absorbs start-up surges while still clearing faults quickly.
Commercial Distribution Boards
Facility teams rely on it for lighting and socket circuits that feed equipment with moderate inrush. The 6 kA rating matches common panelboard fault levels.
DC Auxiliary Circuits
With a 125V DC rating, this breaker also suits DC control and auxiliary supplies. That flexibility reduces the number of different part numbers a maintenance team must stock.
Replacement and Upgrade Guide
Upgrading an older Acti9 panel is straightforward. The iC60N 1P C20 shares the same 35 mm DIN rail footprint and 18 mm width as many legacy breakers. That means less rewiring and faster changeover during planned shutdowns.
Before ordering, confirm the existing breaker’s pole count, rated current, and trip curve. Match those values to the iC60N 1P C20 to keep coordination intact. Also check that the panel’s fault level does not exceed the 6 kA breaking capacity.
When replacing a B-curve device on a motor circuit, the C-curve often reduces nuisance trips. This single change can cut callouts and improve uptime. SpareTechPLC supplies this model as an active, in-production part.
Installation and Setup
Mount the breaker on a 35 mm DIN rail and snap it into place. Verify that the supply is isolated before any work begins. Follow local wiring regulations and the manufacturer’s instructions at all times.
Keep the module’s ventilation clear. The operating range of -35 to 70 °C gives margin, but crowded enclosures still need airflow. Label each circuit clearly to speed future maintenance.
Maintenance and Reliability
The iC60N 1P C20 offers 20,000 mechanical cycles and 10,000 electrical cycles. That long service life lowers replacement costs over the panel’s lifetime. Inspect breakers periodically for signs of heat or loose terminals.
Test tripping only with approved methods. Replace any device that shows discoloration or mechanical damage. Keeping spare units on hand shortens unplanned downtime.
Compatibility and Integration
This breaker fits standard 35 mm DIN rail systems used across industrial panels. It works alongside common Acti9 accessories and distribution components. The dual standard compliance, EN/IEC 60898-1 and EN/IEC 60947-2, supports use in both residential-style and industrial applications.
