Siemens 3RV2411-1BA10 Circuit Breaker for Transformer Protection, 1.4-2A, 3-Pole, Size S00

The Siemens 3RV2411-1BA10 is a professional-grade 3-pole circuit breaker engineered specifically for the reliable protection of transformers. Housed in a compact S00 frame size, this device offers precise current monitoring with an adjustable thermal overload release range between 1.4 and 2A. It serves as a critical component in industrial electrical infrastructure, providing robust defense against short circuits and overloads to maintain the integrity and operational lifespan of sensitive transformer equipment.

Advantages

This circuit breaker stands out due to its specialized design for transformer applications, ensuring that the specific inrush current characteristics of transformers are managed effectively. The compact S00 design allows for space-efficient installation in control cabinets, making it ideal for modern industrial setups where panel space is at a premium. Its high-quality construction ensures consistent performance and durability under demanding operational conditions, while the adjustable release range provides the flexibility needed to match the specific requirements of the connected load.

Suitable for

• Protection of control transformers in industrial automation
• Safeguarding power supply units in electrical control panels
• Integration into machinery requiring reliable overcurrent protection
• Applications where space-saving components are necessary

When it may not be suitable

This device is specifically calibrated for transformer protection and may not be suitable for standard motor protection applications, which often require different tripping characteristics. It should not be used in circuits exceeding its rated current range or in environments that fall outside its specified operating temperature and ingress protection ratings.

Key specifications

• Number of poles: 3
• Current setting range: 1.4 to 2A
• Size: S00
• Function: Transformer protection

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a control cabinet. Once mounted, connect the primary side of the transformer to the input terminals and the load to the output terminals. Use the adjustment dial on the front of the unit to set the thermal release to the specific current value required by your transformer application. Ensure all terminal screws are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the transformer's rated primary current falls within the 1.4 to 2A range
• Ensure the S00 frame size is compatible with your existing DIN rail layout
• Confirm that the application is for transformer protection rather than motor protection
• Check environmental conditions to ensure they meet the device's operational requirements

Usage recommendations

Regularly inspect the circuit breaker for signs of wear or thermal damage. Periodically test the tripping mechanism to ensure the device remains functional and capable of providing the intended protection for your electrical system.
