Circuit breaker DPX3 250 HP EL S1 3P 160 A 70 kA 423242

Three-pole circuit breaker DPX3 250 HP EL S1 – reliable installation protection

This three-pole DPX3 250 HP EL S1 circuit breaker with a rated current of 160A is a solid solution for protecting electrical circuits. The ability to switch off short circuits at 70 kA at 400V provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage and downtime in the installation. Equipped with an S1 type electrical overload release, it reacts quickly and precisely to changes in load.

Design and application

The DPX3 250 HP EL S1 circuit breaker is designed for permanent mounting, which guarantees stability and operational safety. Its design allows for connection of conductors using bolted connections, ensuring a secure and durable connection. Thanks to two switchable auxiliary contacts, the circuit breaker can be integrated with control and signaling systems, increasing the functionality of the installation. A wide range of rated voltages (230…690 V) makes it versatile and can be used in various applications.

Key features and benefits

• High short-circuit breaking capacity (70 kA): Provides effective protection against damage caused by short circuits, protecting equipment and infrastructure.
• S1 type electrical overload release: Allows precise adjustment of the circuit breaker characteristics to the specifics of the load, ensuring optimal protection and minimizing the risk of unnecessary tripping. C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting motors well.
• Wide range of overload release setting (64…160 A): Allows adaptation to different loads and provides flexibility in installation design.
• Possibility of mounting a motor drive: Enables remote control of the circuit breaker, which is particularly useful in automated systems.
• Tripping indicator: Facilitates identification of the circuit breaker status and quick location of problems in the installation.
• Protection degree IP30: Provides basic protection against touching and ingress of solid objects, increasing safety of use.
• Compliance with IEC 60947-2 standard: Guarantees compliance with stringent safety and quality standards.

The DPX3 250 HP EL S1 circuit breaker is a reliable solution for both professional installers and end-users looking for safe and effective protection of their electrical installations. Its solid construction, high quality workmanship and advanced features make it an investment for years to come.
