Power switch 3P, 36kA, TM EB2 250/3S 250A 3P 004671083

Reliable circuit protection with ETI EB2 power circuit breaker

This three-pole EB2 250/3S power circuit breaker is a robust solution for protecting electrical installations. Designed by ETI POLAM, it provides effective protection against overloads and short circuits in circuits with a current of up to 250A. This circuit breaker is suitable for both industrial and commercial installations, as well as residential buildings where high reliability and safety are required.

Characteristics and application

The EB2 250/3S circuit breaker is characterized by a high short-circuit breaking capacity – up to 36kA at 400V. This means that in the event of a short circuit, the circuit breaker will quickly and effectively disconnect the circuit, minimizing the risk of damage to equipment and fire. The thermal adjustment in the range of 157.5…250A and magnetic setting (1500…2500A) allow for precise adjustment of operating parameters to the specific requirements of the installation. Therefore, this circuit breaker can be used to protect various receivers, such as motors, power cables and other electrical devices. Mounting is done by screw connection, which ensures a secure and durable connection with the wires.

Functionality and benefits

• High short-circuit breaking capacity (36kA): Guarantees quick and safe disconnection of the circuit in the event of a failure, protecting equipment and installation from damage.
• Adjustable protection current: Possibility of precise adjustment of operating parameters to the needs of a specific installation.
• Versatile application: Ideal for protecting cables, power leads, motors and electrical apparatus.
• Durable construction: Made of high-quality materials, ensuring long life and reliability.
• Trip indicator: Facilitates identification of the cause of the circuit disconnection – whether due to overload or short circuit.
• Possibility of mounting additional accessories: A wide range of accessories (overcurrent releases, motor drives, etc.) allows for expanding the functionality of the circuit breaker.
• Compliance with standards: Meets the requirements of PN-EN 60947-2 standard, which confirms its safety and quality.
• Protection degree IP20: Provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm.

Thanks to its reliability and functionality, the ETI EB2 250/3S circuit breaker is an optimal solution for professionals and users looking for solid protection of their electrical installations.
