Siemens 3RV2011-1AA10 Motor Circuit Breaker 3-Pole 0.55kW 1.1-1.6A S00

The Siemens 3RV2011-1AA10 is a high-performance 3-pole motor circuit breaker engineered for the reliable protection of electrical motors. Designed in the compact S00 size, this device is specifically optimized for motors with a power rating of up to 0.55 kW. It integrates advanced thermal overload and short-circuit protection mechanisms to safeguard industrial control systems against electrical faults, thereby extending the service life of connected machinery and ensuring consistent operational safety.

Advantages

This motor circuit breaker offers exceptional reliability through its precise thermal overload release, which can be adjusted within the range of 1.1 to 1.6 A to match specific motor requirements. Its compact S00 design allows for efficient space utilization within control cabinets, making it an ideal choice for modern industrial environments where panel space is limited. The robust construction ensures high durability and consistent performance even under demanding operating conditions, providing a dependable solution for motor management.

Suitable for

• Industrial motor control systems
• Protection of small electric motors up to 0.55 kW
• Control panels and switchgear assemblies
• Automation and manufacturing equipment

When it may not be suitable

This device is not intended for use with motors exceeding the 0.55 kW power rating or applications requiring current settings outside the 1.1 to 1.6 A range. It is also not suitable for environments that require specific ingress protection ratings beyond standard industrial cabinet enclosures.

Key specifications

• Number of poles: 3
• Rated power: 0.55 kW
• Adjustable thermal overload release range: 1.1 to 1.6 A
• Size: S00
• Function: Short-circuit and overload protection

How to use

The circuit breaker should be installed by a qualified professional within a standard electrical control cabinet. Mount the device onto a compatible DIN rail and connect the power supply and motor cables to the designated terminals, ensuring all connections are tightened to the specified torque. Once installed, adjust the thermal release dial to the rated current of the connected motor to ensure accurate protection. The device can be manually switched on or off using the front-mounted toggle, and it will automatically trip in the event of an overload or short circuit.

What to consider before purchase

• Verify the rated current of your motor matches the 1.1 to 1.6 A adjustment range
• Ensure the motor power does not exceed 0.55 kW
• Check available space in your control cabinet for S00 size components
• Confirm compatibility with your existing DIN rail mounting system

Usage recommendations

Regularly inspect the device for signs of wear and perform periodic testing of the tripping mechanism to ensure continued operational safety and compliance with electrical standards.
