1-0-2 switch with motor drive MLBS 400 4P CO 230VAC 004661920

Motor-driven switch – reliable load switching

The MLBS 400 4P CO 230VAC switch is a robust solution for switching loads in electrical installations. Designed to operate at 230VAC, it offers reliable switching between two power sources or loads. The motor-driven design provides convenience and precision in switching operations, especially in applications requiring frequent configuration changes.

Construction and application

The four-pole switch (4P) allows for the safe disconnection of all phases and the neutral conductor, which is important for larger loads. The 1-0-2 switch type allows you to choose between two power sources (position 1 or 2) or completely disconnect the circuit (position 0). This makes it suitable for emergency power systems where automatic switching to a backup source is critical for continuous operation. It will also work in installations where remote load control is required.

Parameters and benefits

The MLBS 400 switch is characterized by high technical parameters that guarantee its reliability and safety of use. The rated operating current AC-21 is as high as 400A at 415V, allowing it to handle even demanding receivers. The rated insulation voltage of 1000V and the maximum operating voltage of 690V provide effective protection against overvoltage and short circuits. The thermal current Ith is 400A, which means the device is adapted to work under high thermal load conditions. The control voltage of 230VAC facilitates integration with existing control systems. It is worth emphasizing that the solid construction and high quality of workmanship translate into a long service life of the device and minimize the risk of failure.
