DPX3 circuit breaker 250 HP 4P 40 A 100 kA 423169

Compact Circuit Breaker – Reliable Protection for Installations

This four-pole DPX3 250 HP circuit breaker, rated at 40A and with a short-circuit breaking capacity of 100 kA, is a robust solution for protecting electrical circuits. It performs reliably in both industrial installations and public buildings, providing effective protection against overloads and short circuits.

Design and Functionality

The breaker features a universal rated voltage range of 230-690V, making it compatible with various power systems. The adjustable thermal trip setting range of 32-40A allows precise tuning to match the characteristics of the protected circuit. It is equipped with an off-position indicator for quick status identification. Main contacts are connected via bolted terminals, ensuring secure and durable connections.

• High short-circuit breaking capacity: 100 kA at 400 V ensures effective protection during severe network faults.
• Adjustable overload current setting: Setting range 32-40A enables optimal adaptation to load characteristics.
• Wide voltage compatibility: Operation in the range 230-690V expands application possibilities.
• Robust construction: Fixed mounting ensures stability and reliable operation.
• Optional motorized drive: An optional motorized actuator enables remote control of the breaker.

Applications and Compliance with Standards

The DPX3 250 HP breaker is suitable for protecting various types of circuits, including:

• Main and distribution boards
• Circuits supplying high-power equipment
• Industrial and commercial installations

The IP30 protection rating provides protection against contact and ingress of solid objects larger than 2.5 mm. The device complies with relevant safety standards, ensuring safe and reliable operation. Note: It does not include integrated earth fault protection; additional protective measures must be implemented in installations requiring such protection. Auxiliary contact connections (not included as standard) allow integration with control and signaling systems.
