Siemens 3VU1 300 1MM00 Motor Protection Circuit Breakers

The Siemens 3VU1 300 1MM00 Motor Protection Circuit Breaker is an advanced and reliable solution for safeguarding motors and electrical systems in various industrial applications. Designed with precision and robust engineering, it provides protection against overload, single phasing, and short-circuit faults, ensuring efficient operation and enhanced system longevity.

Key Features and Benefits

High-Performance Protection:

The 3VU13 and 3VU16 motor protection circuit breakers are optimized for fuseless motor feeders up to 11 kW and 22 kW, with current ratings of 25 A and 63 A, respectively. The devices operate on the current-limiting principle, which ensures faster fault clearing by interrupting short-circuit currents within half a cycle. This mechanism prevents the fault current from reaching its peak, reducing the connected equipment's stress.

Versatile Applications:

• Motor Protection: Equipped with overload, short-circuit, and phase-loss protection, these breakers safeguard three-phase motors with adjustable overload settings and fixed short-circuit releases.
• Distribution Feeder Protection: Ideal for protecting distribution feeders, the 3VU13 supports currents up to 25 A, while the 3VU16 handles up to 63 A, with adjustable overload and fixed short-circuit settings.
• Transformer Protection: A specialized range of the 3VU13 is designed for primary-side transformer protection. It accommodates inrush currents with a short-circuit release set at 19 times the rated current.
• Fuse Monitoring: The 3VU1340-1MS00 variant offers integrated fuse monitoring to prevent single phasing by tripping the motor upon fuse failure, ensuring operational safety.

Compact and Reliable Design:

The circuit breakers feature a compact form factor, trip-free mechanisms, and a toggle switch for clear ON/OFF indication. Ambient temperature compensation up to 55°C ensures consistent performance without derating, while finger-safe terminals enhance operator safety.

1. What is the primary function of Siemens 3VU13 and 3VU16 circuit breakers?

These circuit breakers protect motors, transformers, and distribution feeders from overload, short-circuit, and phase-loss faults. They are designed for fuseless motor feeders and offer reliable, high-performance protection.

2. What motor power ratings can the 3VU13 and 3VU16 handle?

The 3VU13 is suitable for motors up to 11 kW (25 A).

The 3VU16 is designed for motors up to 22 kW (63 A).

3. What are the key applications of these circuit breakers?

The primary applications include:

Motor protection for three-phase motors.

Distribution feeder protection up to 25 A (3VU13) and 63 A (3VU16).

Transformer primary-side protection with specialized settings for inrush currents.

Fuse monitoring to prevent single phasing.

4. How do these breakers achieve current limits?

The 3VU circuit breakers use a current-limiting principle. During a short-circuit event, the contacts open electrodynamically, creating a large arc voltage in the arc chamber. This quickly interrupts the fault current within half a cycle or less.

5. Are these circuit breakers compliant with international standards?

Yes, the 3VU13 and 3VU16 conform to the following standards:

IS/IEC 60947-1

IS/IEC 60947-2
