Siemens 5SL6302-7 Miniature Circuit Breaker 3-Pole C 2A 6kA

The Siemens 5SL6302-7 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for high reliability, this device effectively monitors current flow to prevent damage from overloads and short circuits in AC electrical systems. Its compact design and high-quality construction ensure it integrates seamlessly into modern distribution boards, offering consistent performance and safety for both residential and industrial electrical infrastructures.

Advantages

This miniature circuit breaker stands out due to its precise C-characteristic, which allows for a balanced response to current surges, making it ideal for various electrical loads. The 3-pole configuration provides comprehensive protection across three phases, enhancing the safety of complex electrical setups. With a breaking capacity of 6kA, it is capable of handling significant fault currents, thereby protecting downstream equipment and wiring from potential thermal or mechanical damage. Its durable build quality ensures a long service life, reducing the need for frequent maintenance or replacements.

Suitable for

• Residential electrical distribution boards
• Industrial control panels and machinery
• Protection of lighting circuits
• Small motor control applications
• Commercial building electrical systems

When it may not be suitable

This device is not intended for use in DC electrical systems, as it is specifically designed for AC applications. Furthermore, it may not be suitable for circuits requiring a different tripping characteristic, such as B or D, or for applications where the expected short-circuit current exceeds the 6kA breaking capacity.

Key specifications

• Number of poles: 3
• Rated current: 2A
• Tripping characteristic: C
• Breaking capacity: 6kA
• System voltage: AC

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the power supply is disconnected before installation. Connect the incoming supply 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. Once installed, the device can be switched on by moving the toggle lever to the upward position. In the event of a trip, the lever will move to the center or off position; investigate the cause of the fault before resetting the breaker.

What to consider before purchase

• Verify that the 2A rated current matches the requirements of your specific circuit load.
• Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that the 3-pole configuration is appropriate for your phase setup.
• Check that the mounting space in your distribution board is compatible with standard DIN rail components.

Usage recommendations

Always adhere to local electrical codes and safety regulations during installation. Regularly inspect the circuit breaker for signs of wear or heat damage and perform periodic testing to ensure the mechanism remains functional.
