Siemens 5SL6210-7 Miniature Circuit Breaker, 2-Pole, C10A, 6kA

The Siemens 5SL6210-7 is a high-quality 2-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in residential and commercial environments. This device is designed to safeguard wiring and connected equipment by automatically interrupting the power supply in the event of an overload or short circuit. With its robust construction and precise engineering, it serves as a critical component in modern electrical distribution boards, ensuring consistent performance and safety for various electrical installations.

Advantages

This miniature circuit breaker offers exceptional reliability and durability, meeting stringent safety standards for electrical protection. Its C-characteristic makes it highly versatile, allowing it to handle moderate inrush currents commonly found in lighting and small motor applications without nuisance tripping. The 2-pole design allows for the simultaneous disconnection of both phase and neutral conductors, providing an added layer of safety during maintenance or fault conditions. Furthermore, the 6kA breaking capacity ensures that the device can effectively manage significant fault currents, protecting the integrity of the electrical system.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• Small motor control applications
• Protection of household appliances
• General electrical installation projects

This circuit breaker may not be suitable for industrial applications requiring high-performance breaking capacities exceeding 6kA or for circuits with extremely high inrush currents that would necessitate a D-characteristic breaker. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.

Key specifications

• Number of poles: 2
• Rated current: 10A
• Tripping characteristic: C
• Breaking capacity: 6kA
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed to be snapped onto a standard 35mm DIN rail within a distribution box. Ensure that the supply voltage is disconnected before beginning the installation process. Connect the incoming power lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 10A rating matches your circuit load requirements
• Ensure the 6kA breaking capacity is sufficient for your installation's prospective short-circuit current
• Check that your distribution board has available space on the DIN rail
• Confirm that the C-characteristic is appropriate for your specific load type

Usage recommendations

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform a functional test periodically to ensure the mechanism remains operational. If the breaker trips, investigate the cause of the overload or short circuit before resetting the switch.
