Schneider Electric iC65N 2P C16A — Dual-Pole Overcurrent Protection | Acti9 Platform
Engineering Background: The Schneider Electric Acti9 iC65N series is engineered for residential, commercial, and light industrial distribution boards where reliable overcurrent and short-circuit protection is non-negotiable. The iC65N-2P-C16A is a 2-pole, 16 A, C-curve miniature circuit breaker (MCB) with a 6 kA rated breaking capacity at 230/400 V AC, fully compliant with IEC 60898-1 and EN 60898-1.
Product Positioning: Designed for procurement engineers and panel builders sourcing IEC-certified protection devices for final distribution circuits — lighting, socket outlets, and motor loads with moderate inrush. The iC65N platform offers a compact 18 mm/pole DIN-rail footprint, making it the preferred choice for high-density enclosures where space and reliability are equally critical.

Proven Application Environments
- Residential Distribution Boards: Final circuit protection for lighting (≤16 A) and socket-outlet circuits in apartments and villas.
- Commercial Buildings: Office fit-outs, retail units, and hospitality projects requiring IEC-certified MCBs in compact consumer units.
- Light Industrial Panels: Control panel branch protection for PLC power supplies, HMI units, and 24 V DC SMPS inputs (via appropriate transformer).
- Data & Telecom Rooms: UPS bypass and PDU branch circuit protection where nuisance tripping must be minimized (C-curve).
- Machine Building: Supplementary protection for control transformers and auxiliary circuits in IEC-compliant machinery.
Engineering Advantages
- Visi-Trip Indicator: Clearly distinguishes between tripped (fault) and manually OFF states — critical for rapid fault diagnosis in live panels.
- Compact 18 mm/pole Footprint: Maximizes circuit density in standard 9-module DIN rail enclosures.
- Acti9 Ecosystem Compatibility: Accepts iOF (auxiliary contact), iSD (shunt trip), iMN (undervoltage release), and Rotary Handle accessories without rewiring.
- Vibration & Shock Resistance: Qualified to IEC 60068-2-6 — suitable for transportation and industrial environments.
- Halogen-Free Housing: Compliant with RoHS Directive 2011/65/EU; reduced smoke toxicity in fire scenarios.
- Consistent Tripping Characteristics: Factory-calibrated thermal-magnetic trip unit ensures repeatable protection across the full temperature range.
System Architecture & Signal Flow
The iC65N-2P-C16A integrates into the Acti9 distribution architecture as follows:
- Upstream: Fed from Acti9 iC60N/iC60H RCCB or iDT40N isolator via busbar comb (A9XPH212 or equivalent).
- Protection Layer: Thermal-magnetic trip unit provides overload protection (thermal bimetal, time-inverse) and short-circuit protection (magnetic instantaneous, C-curve: 5–10× In).
- Downstream: Feeds final circuits — lighting, sockets, or control loads — via standard 2.5–6 mm² copper conductors.
- Accessories: iOF auxiliary contact signals breaker state to BMS/SCADA; iSD shunt trip enables remote tripping from fire alarm or emergency stop systems.
- Metering (optional): Pair with Acti9 iEM2000 energy meter for per-circuit kWh monitoring without additional CT wiring.
Sourcing & Quality Verification
- OEM Traceability: Each unit ships with Schneider Electric original packaging, holographic authenticity label, and factory QC seal intact.

Technical FAQ
Q: What is the difference between iC65N and iC65H?
A: The iC65H has a higher rated breaking capacity (10 kA vs 6 kA for iC65N). For standard residential and commercial applications with prospective short-circuit current ≤6 kA, the iC65N is fully adequate and more cost-effective.
Q: Can the iC65N-2P-C16A be used on a 3-phase 400 V system?
A: Yes. The 2P configuration protects two phases (or phase + neutral) in a 3-phase system. Rated voltage is 230/400 V AC.
Q: Is the C-curve appropriate for motor loads?
A: C-curve (5–10× In instantaneous) is suitable for loads with moderate inrush (e.g., small motors, transformers, fluorescent lighting). For high-inrush motors, consider D-curve (iC65N-2P-C16A-D).
Q: What accessories are compatible?
A: The full Acti9 accessory range is compatible: iOF (auxiliary contact), iSD (shunt trip), iMN (undervoltage release), iRC (remote control), and rotary handle kits.
