5SL6340-7BB SIEMENS

The 5SL6340-7BB is a miniature circuit breaker (MCB) manufactured by Siemens, designed for reliable circuit protection in residential, commercial, and industrial applications. This MCB is a 3+N-pole device, meaning it has three poles for phase conductors and one pole for the neutral conductor, ensuring comprehensive protection for three-phase systems with a neutral connection. It has a C-curve tripping characteristic, which provides a balance between sensitivity and immunity to nuisance tripping, making it suitable for circuits with moderate inrush currents. With a rated current of 63A, this MCB can handle substantial loads, safeguarding circuits against overloads and short circuits. The 5SL6340-7BB is rated for a voltage of 400V, making it compatible with standard European power systems. It has a high breaking capacity of 10kA, meaning it can safely interrupt fault currents up to 10,000 amps, preventing damage to equipment and ensuring safety. This MCB offers reliable protection against overcurrents and short circuits, enhancing the safety and reliability of electrical installations. It is designed for DIN rail mounting, allowing for easy installation in distribution boards and control panels. The Siemens 5SL6340-7BB is a robust and dependable circuit protection device.
