Siemens MCB, DIN Rail Mounting, 159g Weight - SENTRON Series - 5SY6104-7
Protect electrical systems and devices against overload and short circuits with this MCB from Siemens. It permanently monitors a system and cuts a connected circuit in the event of a power surge, which minimises the risk of damage to equipment. As unaffected loads continue to function, you benefit from increased plant availability. The unit resists vibration and has a wide operating temperature range between -25°C and +55°C, making it compatible with demanding settings. This MCB meets the requirements of automated systems and industrial power supply setups, like those found in data centres and semiconductor industries.
