SCHNEIDER 140AII33000 Miniature Circuit Breakers

Schneider Electric is a global leader in low-voltage protection, and their Miniature Circuit Breaker (MCB) range—specifically the Acti9 and Multi9 series—is considered the industry gold standard for safety and reliability.

1. Product Detailed Description

Schneider MCBs are electromechanical devices designed to protect electrical circuits from overloads (thermal protection) and short-circuits (magnetic protection).

The flagship Acti9 iC60 series is modular, meaning it can be easily snapped onto a DIN rail and integrated with various accessories (auxiliary contacts, shunt trips, etc.). They are designed to operate in harsh industrial environments while remaining simple enough for residential distribution boards.

2. Key Product Parameters

While specific values depend on the model (e.g., iC60N vs. iC60H), the general range includes:

3. Product Advantages

• VisiSafe: A green visible strip on the toggle indicates the “physical” opening of the contacts, ensuring downstream maintenance is 100% safe.

• VisiTrip: A red window on the front face pops up instantly when the breaker trips due to a fault, allowing for rapid troubleshooting.

• Class-2 Insulation: The only device on the market offering this level of safety; the distance between the breaker surfaces and internal parts is double the industry requirement.

• Fast Closing: The mechanism reduces wear and tear on the contacts during closing, extending the product’s lifespan.

• Global Compliance: Meets both IEC/EN 60898-1 (Residential) and IEC/EN 60947-2 (Industrial) standards.

4. Important Considerations (Precautions)

• Curve Selection: Choosing the wrong curve (e.g., using a B-curve for a motor) will result in “nuisance tripping” due to high inrush currents.

• Terminal Torque: Always use a calibrated screwdriver. Loose connections are the leading cause of electrical fires in breaker panels.

• Cascading & Selectivity: When designing a system, ensure the upstream breaker is coordinated with the Schneider MCB so that only the breaker closest to the fault trips.

• Direction of Feed: Most modern Acti9 MCBs allow “top-in/bottom-out” or “bottom-in/top-out” wiring, but always verify the specific model markings.

5. Typical Product Applications

• Residential & Commercial: Protecting lighting circuits, power outlets, and IT equipment (typically B or C curves).

• Industrial Automation: Protecting control circuits, small motors, and power supplies (typically C or D curves).

• Infrastructure: Used in transport, telecommunications, and water treatment plants where high-breaking capacity and reliability are non-negotiable.

• Renewable Energy: Specialized DC versions (e.g., iC60H-DC) are used in solar PV string protection.
