DPX3 circuit breaker 250 HP 3P 200 A 36 kA 423011

Three-pole breaker DPX3 250 – reliable protection for electrical installations

The DPX3 250 power breaker is a robust solution for protecting electrical circuits. Designed for three-phase systems, it provides effective protection against overloads and short circuits, ensuring the safety of installations and connected equipment. With a rated continuous current of 200A and a high short-circuit breaking capacity of 36kA at 400V, it is an ideal choice for demanding industrial and commercial applications.

Functionality and design

The DPX3 250 breaker features three poles, enabling full protection of three-phase circuits. It includes two reversible auxiliary contacts that allow integration with control and signaling systems. The adjustable thermal overload trip range (160-200A) enables precise tuning to the load characteristics, while the short-circuit trip range (1000-2000A) ensures rapid response during fault conditions. Connection is made via bolted terminals on the front of the device, simplifying installation and maintenance.

• High short-circuit breaking capacity: 36kA at 400V ensures fast and safe disconnection during faults.
• Adjustable thermal overload trip: Allows customization to the protected circuit’s profile, preventing unnecessary tripping.
• Two auxiliary contacts: Enable integration with external control and status signaling systems.
• Robust construction: Fixed mounting ensures long-term stability and reliable operation.
• Trip indicator: Clearly shows whether the breaker has tripped and requires intervention.
• Motorized operating mechanism option: Optional motor drive enables remote control, particularly useful in automated systems.

The DPX3 250 is compatible with a rated voltage range of 230-690V and features an IP30 protection rating, safeguarding against finger contact and ingress of solid objects larger than 2.5 mm. Compliance with safety standards guarantees reliable operation and safe use. This is a complete, ready-to-install protection unit, fully operational immediately after unpacking.
