Siemens 3VU1300-1MG00

Siemens 3VU1300-1MG00 Motor Protection Circuit Breaker

Overview

The Siemens 3VU1300-1MG00 is a high-performance motor protection circuit breaker to safeguard electrical motors from overload, phase failure, and short circuits. It provides reliable and efficient motor protection while ensuring safe operation in industrial and commercial applications. With an adjustable overload release range of 1A to 1.6A and a fixed short-circuit release at 19A, this breaker is engineered to deliver precise and consistent protection. The inclusion of auxiliary contacts (1NO+1NC) enhances operational control and monitoring, while the screw terminal connections ensure secure and stable wiring.

Applications

Motor Protection

The Siemens 3VU1300-1MG00 protects three-phase motors from potential electrical faults such as overload, short circuits, and phase loss. By preventing damage caused by excessive currents, it ensures motor longevity and efficiency.

Distribution Feeder Protection

Apart from motor protection, this breaker is used to secure distribution feeders. It offers adjustable overload and fixed short-circuit protection, making it suitable for disconnecting and protecting electrical feeders up to 1.6A.

Transformer Protection

This circuit breaker can also protect the primary side of transformers. A short-circuit release set at 19 times the rated current effectively mitigates inrush currents and prevents potential damage to the transformer.

Key Features and Benefits

High Performance

• Instantaneous Tripping: Operates on the current-limiting principle, ensuring rapid response to short circuits.
