DPX3 circuit breaker 250 HP 4P 32 A 100 kA 423168

Four-pole circuit breaker DPX3 250 HP – Reliable protection for electrical installations

This four-pole DPX3 250 HP circuit breaker is a robust solution for protecting electrical circuits. Designed for operation in systems with voltage up to 690V, it provides effective protection against overloads and short circuits. With a rated continuous current of 32A and a high short-circuit breaking capacity of 100kA at 400V, it ensures safety and stable performance even under demanding conditions.

Functionality and applications

This breaker is suitable for use in commercial buildings, industrial facilities, and residential installations where high reliability and safety are required. Thanks to the option of installing an optional motorized drive, remote control of the breaker is possible, enhancing user comfort and facilitating integration with building automation systems. The trip indicator enables quick identification of the breaker’s status, simplifying diagnostics and maintenance. Connections are made via bolted terminals, ensuring secure and durable conductor connections.

Specifications and benefits

• High short-circuit breaking capacity: 100kA at 400V ensures effective protection of installations against the effects of sudden voltage surges.
• Adjustable rated current: The overload trip setting range (25–32A) allows precise adaptation to the specific requirements of the installation.
• Robust construction: The permanently mounted device, constructed from high-quality materials, guarantees long-term, fault-free operation.
• Versatility: Compatibility with systems up to 690V extends its range of applications.
• Safety: The absence of integrated earth fault protection does not diminish its role in safeguarding against overloads and short circuits—this is standard for this type of breaker.
• Flexibility: Optional motorized drive enables remote operation of the breaker.
• Clear signaling: The trip indicator facilitates rapid identification of the device’s status.
• Overload protection: The short-circuit trip setting range (0–400A) allows customization to the specific characteristics of the protected circuit.

IP30 protection rating provides basic protection against contact and ingress of solid objects, making it safe for use in various working environments.
