Safety for your protection

CEAG main circuit breakers enable the connection or disconnection of circuits under normal operating conditions, as well as the switching, short-term conduction, and interruption of currents in exceptional situations, such as short circuits.

Full switching capacity for motors in the AC-3 category

Full switching capacity for motors in the AC-3 category and insulation properties in accordance with the EN 60947-4-1 standard with mandatory opening of the main contacts in accordance with the EN 60204-1 standard are just some of the important features offered by CEAG circuit breakers.

Versions up to 180 A optionally offer a high degree of protection of IP66. The switch position is always clearly visible and easy to recognize.

The main circuit breakers feature an installation-friendly design and easily accessible connection terminals.

Metal versions can be equipped with screw-on flanges for easy system integration and cost-effective service life extension. Optionally, they can be supplied with plastic or brass snap-on flanges.

These circuit breakers are also available in versions for Explosion Group IIB, which is sufficient for many applications.
