Schneider C063N320FM | Circuit breaker, ComPacT NS630bN, 50kA at 415VAC, 3P, fixed, manually operated, MicroLogic 2.0 control unit, 630A
Product Name: Schneider C063N320FM
This is a molded case circuit breaker (MCCB) from the ComPacT NS630bN series. It’s designed for medium- to high-power electrical distribution systems and is commonly used in industrial and commercial settings.
Detailed Breakdown:
1. Type:
ComPacT NS630bN Series
-
A range of MCCBs designed for high performance, reliability, and compact size.
-
The “bN” indicates a specific mechanical design with a compact body and certain performance characteristics.
2. Breaking Capacity:
50 kA at 415 VAC
-
This is the maximum fault current the breaker can safely interrupt.
-
50,000 amps at 415 volts AC – this means it can handle large short-circuit events without damage.
-
This rating makes it suitable for heavy-duty systems.
3. Poles:

3P (Three Poles)
-
It protects three-phase systems.
-
Each pole is connected to one phase: L1, L2, and L3.
4. Mounting:
Fixed Type
-
The circuit breaker is installed directly and permanently into the panel.
-
Not withdrawable or plug-in type.
-
Lower cost and simpler installation, but not as easy to replace or maintain as draw-out types.
5. Operation:
Manually Operated
-
It is switched ON/OFF by hand (no motor mechanism).
-
Manual toggle or rotary handle is used to operate the breaker.
6. Control Unit:
MicroLogic 2.0
-
This is the trip unit or brain of the circuit breaker.
-
MicroLogic 2.0 is a basic electronic protection unit.
-
It provides overload and short-circuit protection with adjustable settings.
-
No advanced metering or communication functions (those are in higher MicroLogic models like 5.0, 6.0, etc.).
7. Rated Current:
630A
-
The maximum continuous current the breaker can carry without tripping.
-
It is suitable for circuits with a full-load current of up to 630 amps.
Applications:
-
Industrial power distribution boards
-
Main breakers in commercial panels
-
Generators and transformer protection
-
Large motor control centers
