The Siemens 3RV2011-1DA20 is a high-performance 3-pole motor circuit breaker engineered to provide reliable protection for electrical motors in industrial environments. This compact device, built in the space-saving S00 size, is specifically designed to safeguard motors against overloads and short circuits, ensuring consistent operational safety and longevity for your electrical systems.

Advantages

This motor circuit breaker offers exceptional reliability through its precise thermal release mechanism, which can be adjusted within the 2.2-3.2A range to match specific motor requirements. Its robust construction allows it to withstand demanding industrial conditions, while the high switching capacity ensures efficient performance during frequent operations. The compact S00 design facilitates easy integration into control cabinets where space is limited, providing a professional solution for motor management.

Suitable for

• Industrial motor control systems
• Protection of electrical motors against overload
• Short-circuit protection in low-voltage distribution
• Applications requiring compact, DIN-rail mounted protection devices

When it may not be suitable

This device is not suitable for applications where the motor current exceeds the 3.2A threshold or falls below the 2.2A range. It is also not intended for use in environments with extreme environmental hazards that exceed the specified protection ratings of the housing.

Key specifications

• Number of poles: 3
• Current setting range: 2.2-3.2A
• Size: S00
• Function: Overload and short-circuit protection

How to use

The device is designed for standard DIN-rail mounting within an electrical enclosure. After mounting, connect the power supply cables to the input terminals and the motor cables to the output terminals. Use the adjustment dial on the front of the unit to set the thermal release to the specific nominal current of the connected motor. Ensure all connections are tightened to the manufacturer's torque specifications before energizing the circuit.

What to consider before purchase

• Verify that the motor's nominal current falls within the 2.2-3.2A range
• Ensure the S00 size is compatible with your existing control cabinet layout
• Check that the voltage and frequency ratings match your local power supply

Usage recommendations

Always perform a functional test after installation and ensure that the thermal release is correctly calibrated to the motor's nameplate data to prevent nuisance tripping or inadequate protection.
