DPX3 250 HP Circuit Breaker – Reliable Protection for High-Load Circuits

This three-pole DPX3 250 HP power breaker is a robust solution designed to protect electrical installations requiring high resistance to overloads and short circuits. Rated for operation in networks with nominal voltages from 230 to 690 V, it ensures effective protection against damage and failures. With a rated continuous current of 250 A and a high short-circuit breaking capacity of 36 kA at 400 V, it guarantees safety even under demanding conditions.

The breaker features a wide range of thermal trip setting (200–250 A) and instantaneous magnetic trip (1250–2500 A), enabling precise adaptation to the load characteristics. Two changeover auxiliary contacts enhance device functionality, allowing seamless integration with control and signaling systems. An off indicator simplifies status identification and rapid troubleshooting.

• High short-circuit breaking capacity: 36 kA at 400 V ensures effective protection against the consequences of sudden surges.
• Wide adjustment range: Enables precise tuning to the protected circuit’s characteristics and prevents unnecessary tripping.
• Three-pole design: Provides comprehensive protection in three-phase systems.
• Motor drive mounting option: Enables remote control of the breaker, particularly useful in automated systems.
• Robust construction: Fixed-mount design made from high-quality materials ensures long-term, reliable operation.
• Two auxiliary contacts: Facilitate integration with external control and status signaling systems.

The DPX3 250 HP breaker is suitable for a wide range of electrical installations, including:

• Main and distribution switchboards
• High-power motor supplies
• High-current circuits
• Industrial and commercial installations

IP30 protection rating safeguards against finger contact and ingress of solid objects larger than 2.5 mm, making it suitable for most industrial and commercial environments. The breaker is supplied with integrated locking for immediate installation and operation. Connection is made via bolted terminals, ensuring secure and durable electrical connections.
