Air contactor CEM25.10-400V-50/60HZ 004645124

Air contactor CEM25.10 – a reliable motor control element

The CEM25.10-400V-50/60Hz contactor is a solid and proven solution for remote switching of electric motors and other energy consumers. Designed for operation in installations with a voltage of 400V, it allows for effective control of loads up to 11 kW (AC-3). The wide range of applications of the contactor includes not only direct motor starting, but also power switching circuits, star-delta and reversing circuits.

Construction and application

The contactor design allows for mounting on TH35 rail or mounting plate, providing flexibility during installation. The ability to connect a surge protector BAM and a dedicated overload relay from the RE series (using the BFE adapter) increases the safety and functionality of the system. In addition, CEM…CN contactors are available in a version for switching capacitors. Front and side auxiliary contacts allow signaling of the contactor's operating status, which is particularly important in applications requiring monitoring and alarming.

Key features and benefits

• High performance: Rated operating current of 25A for AC-3 (400V) and 45A for AC-1 (400V) guarantees reliable operation even under higher loads.
• Versatility: Can be used in various control circuits – from simple motor starting to more complex power switching configurations.
• Safety: Compatibility with RE series overload relays and the ability to connect a surge protector BAM provide effective protection of the installation and connected devices.
• Flexible mounting: The ability to mount on TH35 rail or mounting plate makes installation easier in various conditions.
• Status signaling: Auxiliary contacts allow monitoring of the contactor's operating status and signaling of any failures.
• Mechanical interlock: Mechanical interlock BLIME 9-105 allows connecting contactors of different sizes (CEM9 to CEM105), which facilitates the construction of complex control systems.

The CEM25.10 contactor is a solid choice for professionals and users looking for a reliable solution for controlling electric motors in various industrial and domestic applications. It meets the standards PN-IEC/PN-EN 60 947 and DIN VDE 0660, which confirms its high quality and safety of use.
