Product: Schneider C160N420FM

The C160N420FM is a high-capacity molded case circuit breaker (MCCB) from Schneider Electric’s ComPacT NS1600N series. It is engineered for reliable protection in large-scale industrial and commercial power distribution systems, offering performance and safety for high-current applications.

Detailed Breakdown:

1. Series & Model:

• ComPacT NS1600N

• The “1600” indicates a frame size of 1600A, which defines the maximum rated current the breaker is built to handle.

• The “N” version is a standard performance model with compact construction and high reliability.

2. Rated Current:

• 1600 Amps (A)

• This is the maximum continuous current the breaker can handle without tripping.

• Designed for heavy-duty circuits like main incomers, large machinery, or generator outputs.

3. Breaking Capacity:

• 50 kA at 415 VAC

• The breaker can interrupt a short-circuit current up to 50,000 amps safely.

• Suitable for use in systems with high fault current potential (e.g., near transformers or large motors).

• 

4. Number of Poles:

• 4 Poles (4P)

• Protects three phases and neutral conductor.

• Ideal for systems requiring complete disconnection, including unbalanced loads and neutral protection.

5. Mounting Type:

• Fixed

• Installed permanently into a switchboard or panel.

• Not withdrawable, which means manual disconnection is needed during servicing or replacement.

6. Operation Method:

• Manually Operated

• Operated by hand, using a toggle or rotary handle.

• No motorized mechanism — remote control is not available in this version.

7. Trip Unit / Protection Unit:

• MicroLogic 2.0

• A basic electronic trip unit that provides:

  • Long-time delay protection (for overloads)

  • Short-time delay protection (for short circuits)

• Adjustable protection settings to match system requirements.

• Does not include advanced metering or communication features.

Typical Applications:

• Main circuit breaker for large distribution panels

• Generator or transformer protection

• Industrial power systems with high loads and neutral requirements

• Large commercial buildings, factories, or critical infrastructure
