Introduction
Downtime rarely announces itself. A single unprotected feeder can take an entire production line offline, and that is where the iC60N 4P C16 earns its place in your panel. This Schneider Electric Acti9 iC60 miniature circuit breaker delivers four-pole protection with a 16 A rating and a C trip curve. It is an active, in-production device, so you can standardize new builds and replacements around it with confidence.

Technical Specifications
The iC60N 4P C16 carries a rated current of 16 A across four poles. That means it protects a three-phase circuit plus neutral from a single DIN rail footprint. The C curve trips magnetically at 8×In ±20%, so it tolerates brief inrush currents from small motors and transformers without nuisance tripping. Its 6 kA breaking capacity at 230/400V AC (IEC 60898-1) handles the prospective short-circuit currents found in most commercial and light industrial distribution boards. Rated voltage is 400V AC, and the device conforms to EN/IEC 60898-1 and EN/IEC 60947-2.

Buyer’s Guide: Matching the Breaker to Your Panel
Before you order, confirm three things. First, check that your circuit needs four-pole protection rather than a three-pole device. Second, verify the load current stays within the 16 A rating under normal running conditions. Third, confirm your fault level does not exceed the 6 kA breaking capacity at 400V AC. If all three align, this breaker fits. The 35 mm DIN rail mount and 85 × 72 × 78.5 mm body suit standard enclosures, and the 0.5 kg weight keeps panel loading predictable.

Replacement and Upgrade Path
Engineers replacing older Acti9 devices will find the iC60N 4P C16 a direct fit on 35 mm DIN rail. Its 20,000 mechanical cycles and 10,000 electrical cycles give a clear service-life benchmark. When a breaker nears those counts, plan replacement before failure rather than after. The active lifecycle status means spare units remain available, which simplifies long-term maintenance planning. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Installation Notes
Mount the device on a 35 mm DIN rail and confirm the operating temperature stays within -35 to 70 °C. Follow your local wiring regulations and the manufacturer’s instructions for conductor sizing and torque. Do not modify the breaker or bypass its protection functions.
Maintenance and Reliability
Inspect periodically for signs of overheating, discoloration, or loose connections. Exercise the toggle during planned shutdowns to confirm smooth mechanical operation. Keep the panel free of dust and moisture, and log trip events to spot recurring faults. These habits extend service life and protect the 10,000-cycle electrical rating.
Frequently Asked Questions
What does the C curve mean on this breaker?
The C curve uses thermal-magnetic protection with a magnetic trip threshold of 8×In ±20%. It suits loads with moderate inrush currents, such as small motors and transformers.
Can I use the iC60N 4P C16 on a three-phase system?
Yes. With four poles and a 400V AC rating, it protects three phases plus neutral in a single device.
What is the breaking capacity of this model?
It provides 6 kA at 230/400V under IEC 60898-1, which covers typical commercial and light industrial fault levels.
How long does the breaker last?
Schneider rates it for 20,000 mechanical cycles and 10,000 electrical cycles under normal operating conditions.
