iC60N - 6kA
The iC60N MCB is a Miniature Circuit Breaker series from Schneider Electric, part of their Acti9 range, widely used in residential, commercial, and industrial electrical installations. Below is a clear, practical explanation grounded in Schneider’s published specifications.
What is the iC60N MCB?
The Acti9 iC60N is a multi‑standard miniature circuit breaker designed to protect electrical circuits against:
- Overload current
- Short‑circuit current
- It is also suitable for isolation in accordance with industrial standards
It complies with IEC/EN 60898‑1(household installations) and IEC/EN 60947‑2(industrial installations), which allows it to be used across different environments.
Key technical characteristics
1. Breaking capacity
- 6 kA(Icn) under IEC/EN 60898‑1
- Up to 50 kA(Icu) under IEC/EN 60947‑2, depending on voltage and model
This high breaking capacity makes the iC60N suitable for areas with high fault current levels, such as commercial and industrial panels.
2. Tripping curves
iC60N MCBs are available with different trip characteristics:
- Curve B – trips at ~3–5 × In (sensitive loads)
- Curve C – trips at ~5–10 × In (general-purpose, motors, lighting)
- Curve D – trips at ~10–20 × In (high inrush current equipment)
These curves are defined in the Schneider instruction sheets and standards.
3. Current and pole options
- Rated current (In): typically 0.5 A to 63 A
- Pole configurations:
- 1P
- 1P+N
- 2P
- 3P
- 4P
This flexibility allows the iC60N to be used in single‑phase and three‑phase systems.
Safety and diagnostic features
The iC60N incorporates Schneider Electric safety systems:
- VisiTrip™: a red mechanical indicator on the front that clearly shows which breaker has tripped
- VisiSafe™: a green indicator confirming the contacts are physically open, improving safety during maintenance
Both features are standard across the iC60N range.
Installation and mechanical details
- DIN‑rail mounted(35 mm rail)
- 18 mm module width per pole
- IP20 protection (IP40 when installed in an enclosure)
- Operating temperature range approximately –35 °C to +70 °C, depending on model
These details are specified in the official Schneider instruction documentation.
Typical applications
The iC60N MCB is commonly used in:
- Distribution boards in residential buildings
- Commercial and industrial control panels
- Motor starter circuits (Curve C or D)
- Panels requiring high short‑circuit withstand capacity
Its dual‑standard compliance makes it especially popular with engineers who work across mixed installations.
