Siemens 5SL61057 Miniature Circuit Breaker, 1-Pole, C-Characteristic, 0.5A, 6kA, 230/400V

The Siemens 5SL61057 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. This device is designed to detect and interrupt overcurrent conditions, including both overloads and short circuits, thereby safeguarding connected equipment and wiring from potential damage. With its precise C-characteristic, it is optimized for applications where moderate inrush currents are expected, ensuring reliable performance in various residential and commercial electrical distribution systems.

Advantages

This circuit breaker offers high operational reliability and durability, consistent with the standards expected from Siemens electrical components. Its compact design allows for efficient space utilization within standard distribution boards. The device is built to handle a breaking capacity of 6kA, providing a secure safety margin for typical low-voltage installations. Furthermore, the installation process is straightforward, facilitating quick integration into existing electrical panels while maintaining high safety standards for the entire system.

Suitable for

• Residential electrical distribution boards
• Commercial building power circuits
• Protection of control circuits with moderate inrush currents
• Lighting and small appliance branch circuits

This circuit breaker may not be suitable for applications requiring a different tripping characteristic, such as B-characteristic for purely resistive loads or D-characteristic for high-inductive loads with significant starting currents. It is also not intended for use in systems exceeding its rated voltage or breaking capacity specifications.

Key specifications

• Number of poles: 1
• Rated current: 0.5A
• Tripping characteristic: C
• Breaking capacity: 6kA
• Rated operational voltage: 230/400V AC

The device is designed for mounting on a standard DIN rail within an enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the power supply is disconnected before beginning the installation. The wires should be securely fastened to the terminals, ensuring proper contact to prevent overheating during operation.

What to consider before purchase

• Verify that the 0.5A rated current matches the requirements of your specific circuit
• Ensure the C-characteristic is appropriate for the connected load type
• Check that the 6kA breaking capacity meets the short-circuit current requirements of your installation site
• Confirm compatibility with your existing distribution board and DIN rail system

For optimal safety and longevity, regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to test the functionality of the device periodically according to local maintenance standards.
