## Long description

The Siemens 5SL4320-6 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed to handle a rated current of 20 A and a voltage of 400 V, this device serves as a critical safety component in both residential and industrial power distribution networks. It is built to detect and interrupt overloads and short circuits, thereby safeguarding connected equipment and wiring from potential electrical damage.
Advantages
This circuit breaker offers exceptional reliability and durability, ensuring consistent performance in demanding electrical environments. Its 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive protection for three-phase systems. The high-quality construction minimizes the risk of nuisance tripping while maintaining precise response times during fault conditions, which contributes to the overall stability and safety of the electrical installation.
Suitable for
Residential electrical distribution boards
Industrial machinery power supply protection
Commercial building electrical systems
Three-phase motor circuit protection
When it may not be suitable
This device is not intended for use in direct current (DC) applications unless specifically rated for such use. It is also not suitable for circuits exceeding its 20 A current rating or 400 V voltage limit, as this could lead to improper operation or equipment failure.
Key specifications
Number of poles: 3
Rated current: 20 A
Rated voltage: 400 V
Tripping characteristic: B
Breaking capacity: 10 kA
How to use
The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within an appropriate distribution enclosure. Ensure that the supply cables are securely fastened to the terminals according to the specified torque requirements. Once installed, the device can be manually switched on or off using the front-facing toggle lever. In the event of a fault, the lever will automatically move to the tripped position, indicating that the circuit has been interrupted.
