DPX3 250 HP+RCD 4P 160 A 36 kA circuit breaker 423055

DPX3 250 HP+RCD Circuit Breaker – Reliable Protection for Electrical Installations

This four-pole DPX3 250 HP+RCD circuit breaker, rated at 160A and with a short-circuit breaking capacity of 36kA, offers a robust solution for demanding electrical installations. It provides comprehensive protection against overloads, short circuits, and residual current leakage, ensuring enhanced safety and extended system lifespan. Equipped with an integrated residual current device (RCD), it effectively protects personnel from electric shock.

Functionality and Applications

This breaker is ideal for commercial buildings, industrial facilities, and installations requiring high reliability and safety. Its design allows mounting both on TH35 DIN rails and directly onto panels inside electrical cabinets. Thanks to the ability to connect up to three auxiliary contacts, it can be easily integrated into control and signaling systems. Bolted connections ensure secure and durable wiring terminations.

Key Features and Benefits

• High short-circuit breaking capacity (36kA): Ensures effective protection of the installation even during high fault currents.
• Integrated residual current protection: Enhances user safety by rapidly detecting and disconnecting leakage currents. Adjustable residual current settings (0.03 – 0.3 – 1 – 3 A) allow sensitivity to be tailored to the specific installation.
• Adjustable thermal overload trip: Setting range from 125 to 160 A enables precise matching to the load, minimizing unnecessary tripping.
• Wide rated voltage range (230…690 V): Ensures universal application across various electrical network types.
• Trip indicator: Facilitates quick identification of the cause of tripping, accelerating diagnosis and repair.
• Compatibility with auxiliary accessories: Enables functional expansion according to user requirements.
• IP30 protection rating: Protects against finger contact and ingress of solid objects larger than 2.5 mm – ideal for industrial and commercial environments.
• Fixed-mount construction: Ensures long-term stability and reliable operation throughout its service life.

The DPX3 250 HP+RCD circuit breaker is an investment in the safety and reliability of your electrical installation – a trusted solution valued by professional installers and end-users alike.
