Siemens 3VL5763-3AA36-0AA0 Molded Case Circuit Breaker

Product Dimensions：

The Siemens 3VL5763-3AA36-0AA0 is a high-performance Molded Case Circuit Breaker (MCCB) from the SENTRON VL630 series. It is specifically designed to provide superior protection for electrical installations and motors in industrial and commercial environments.

Product Detailed Description

The 3VL5763-3AA36-0AA0 is a 3-pole circuit breaker with a rated current of 630A. It features an Electronic Trip Unit (ETU), which offers more precise and adjustable protection compared to standard thermal-magnetic breakers. This specific model is designed for system protection, ensuring the safety of cables, busbars, and downstream equipment against overloads and short circuits.

Technical Parameters

Product Advantages

• Precision Electronic Tripping: The ETU10 allows for fine-tuning of the protection settings, which helps in achieving better coordination with other upstream and downstream breakers.
• High Breaking Capacity: With a 70 kA rating at 415V, it can safely interrupt very high fault currents, making it suitable for heavy-duty industrial applications.
• Compact Design: Despite its high current rating, the VL630 series is engineered to save space in power distribution boards and control cabinets.
• Global Compliance: This breaker meets international standards (IEC 60947-1 and 60947-2), ensuring it can be used in projects worldwide.
• Modular Accessories: Easy to equip with auxiliary switches, shunt trips, or undervoltage releases to meet specific automation requirements.

Important Considerations (Precautions)

• Setting the ETU: Before commissioning, the electronic trip unit must be set correctly based on the calculated load and cable cross-sections to avoid nuisance tripping or lack of protection.
• Heat Dissipation: Ensure adequate ventilation in the enclosure. At 630A, the heat generated by the contact resistance can be significant.
• Tightening Torque: Always use a torque wrench to tighten the terminal connections. Loose connections are the primary cause of overheating and electrical fires in MCCBs.
• Testing: Use the “Push-to-Trip” button periodically to ensure the mechanical linkage and the tripping mechanism are functioning properly.

Product Applications

• Main Distribution Boards: Serving as the main incoming or outgoing breaker in industrial power plants and large commercial buildings.
• Motor Control Centers (MCC): Providing short-circuit and overload protection for large 3-phase motors (when used with appropriate motor-rated settings).
• Infrastructure: Used in hospitals, data centers, and airports where high reliability and high breaking capacities are mandatory.
• Renewable Energy: Protection for solar inverters and wind turbine distribution systems.
