Schneider Smart Molded Case Circuit Breaker MVS06N

Regarding the **MVS06N** of Schneider Electric, it should be clearly noted that: **this model is a Smart Molded Case Circuit Breaker (MCCB), not a soft starter**. If you need to know about soft starters, Schneider's **Altistart series** (such as Altistart 22 and Altistart 48) is a more suitable choice. The following is the core information about MVS06N and a comparison with soft starters:

 I. Core Functions and Applications of MVS06N

III. Core Differences between Soft Starters and Circuit Breakers

IV. Selection Recommendations

1. **If a motor soft starter is needed**:

   - **Medium and Small Power (4-400kW)**: Select **Altistart 22**, which has a high cost-performance ratio and is easy to install.

   - **High Power (17-1200A)**: Select **Altistart 48**, which supports complex loads and advanced communication.

2. **If circuit protection is needed**:

   - **Power Distribution System**: Select **MVS06N** or the MasterPact MTZ series circuit breakers.

   - **Motor Control Center (MCC)**: Use a combination of circuit breakers, contactors, and thermal relays, or directly select a motor starter with protection functions (such as the TeSys series).
