Power switch 3P, 50kA, TM EB2 800/3S 800A 3P release 004672161

Reliable power protection in demanding installations

This three-pole EB2 800/3S power circuit breaker is a robust solution for protecting electrical circuits, cables and devices against the effects of overloads and short circuits. Designed by ETI POLAM, it is suitable for both industrial and commercial installations where high reliability and high breaking capacity are required. This circuit breaker is a key element in ensuring the safety and continuity of electrical systems.

Functionality and parameters

The EB2 800/3S circuit breaker is characterized by a rated current of 800A and an impressive short-circuit breaking capacity of 50kA at 400V. Thanks to the adjustable thermal release (range 504…800A) and short-circuit release (range 2520…8000A), the protection parameters can be precisely adjusted to the specifics of the protected circuit. The IP20 degree of protection provides basic protection against touch and contamination. The possibility of mounting additional accessories – such as overcurrent releases, motor drives or auxiliary contacts – allows for expanding the functionality of the circuit breaker and adapting it to individual needs.

• High breaking capacity: 50kA at 400V guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Adjustable protection: The ability to precisely set the thermal and short-circuit tripping currents allows for optimal adaptation to the load characteristics.
• Universal mounting: The device is designed for fixed mounting, which ensures stability and reliability of connections.
• Wide range of accessories: Possibility of expanding functionality by mounting additional modules, such as remote drives or auxiliary contacts.
• Safe use: Equipped with a trip indicator that informs about the operation of the protection.
• Solid construction: Made of high-quality materials, which guarantees long life and resistance to environmental conditions.
