5SP3840-2 SIEMENS

The 5SP3840-2 is a Siemens main miniature circuit breaker (MCB), also known as a circuit breaker (SHU), designed for reliable circuit protection. This MCB features a 3x 1-pole configuration, providing three independent circuits within a single unit. It has a rated current of 40A, making it suitable for applications with moderate to high current demands. The device is designed for a voltage rating of 230/400V, compatible with standard European power systems. Its primary function is to protect electrical circuits from overcurrents caused by overloads or short circuits. The MCB trips and interrupts the circuit when the current exceeds the rated value, preventing damage to equipment and reducing the risk of electrical fires. This model is specifically designed for mounting on 40 mm busbars, ensuring secure and stable installation in distribution boards or electrical panels. Siemens MCBs are known for their quality, reliability, and compliance with international standards, ensuring safe and efficient operation. The 5SP3840-2 provides a compact and effective solution for circuit protection in various residential, commercial, and industrial applications.
