Siemens 3RV2011-0CA10 Motor Circuit Breaker, 3-Pole, 0.18-0.25A, Size S00

The Siemens 3RV2011-0CA10 is a high-quality 3-pole motor circuit breaker engineered to provide robust protection for electrical motors in industrial environments. This compact device, built in the S00 size, is specifically designed to safeguard equipment against overloads and short circuits by offering a precise thermal release range of 0.18 to 0.25 amperes. Its reliable performance ensures that motors operate within safe electrical parameters, minimizing the risk of damage and downtime in complex control systems.

Advantages

This motor circuit breaker stands out due to its compact S00 design, which allows for efficient use of space within control cabinets and electrical panels. The device offers high operational reliability and precise current setting capabilities, ensuring that motor protection is tailored to specific application requirements. Its robust construction supports long-term durability in demanding industrial settings, while the integrated thermal and magnetic release mechanisms provide comprehensive protection against both thermal overloads and instantaneous short-circuit faults.

Suitable for

• Industrial motor control and protection
• Automation systems requiring precise current monitoring
• Electrical distribution panels for small motor loads
• Machine building and manufacturing equipment

When it may not be suitable

This device is not suitable for applications where the motor current exceeds the 0.18-0.25A range, as it will cause nuisance tripping or fail to provide adequate protection. It is also not intended for use in environments with extreme moisture or corrosive gases without appropriate protective enclosures.

Key specifications

• Number of poles: 3
• Current setting range: 0.18-0.25 A
• Size: S00
• Protection type: Thermal and magnetic release

How to use

The motor circuit breaker should be installed by a qualified professional on a standard mounting rail within a control cabinet. Once mounted, the desired current value should be set using the adjustment dial on the front of the unit to match the motor's rated current. After wiring the power supply and motor leads to the corresponding terminals, the device can be switched on manually. Regular inspections should be performed to ensure the terminals remain tight and the device is free from debris.

What to consider before purchase

• Verify that the motor's rated current falls within the 0.18-0.25A range
• Ensure the S00 size fits your existing control panel layout
• Confirm compatibility with your specific voltage and frequency requirements

Usage recommendations

Always ensure the power supply is disconnected before performing any installation or maintenance tasks on the circuit breaker to prevent electrical shock.
