DPX3 125 HP 3P 25 A 50 kA circuit breaker 423642

Three-pole circuit breaker DPX3 125 HP – reliable protection for installations

The DPX3 125 HP breaker is a robust and efficient device designed to protect electrical circuits against overload and short-circuit conditions. Engineered for both professional installers and end users, it ensures safety and reliable operation across a wide range of applications. Its compact design and easy installation make it an ideal solution for both new and upgraded installations.

Specifications and applications

This breaker features a rated current of 25A and an exceptional short-circuit breaking capacity of up to 50kA at 400V. This ensures effective protection against sudden current surges, safeguarding equipment and minimizing the risk of failure. Designed for operation in circuits with a rated voltage range of 220 to 690V, it performs reliably in residential, commercial, and industrial facilities. Its three-pole configuration enables use in three-phase power systems.

Advantages and design features

• High short-circuit breaking capacity: 50kA at 400V ensures effective protection even during major overvoltage events.
• Wide rated voltage range: 220 to 690V ensures universal applicability.
• Adjustable thermal trip setting: Allows setting the tripping threshold between 20–25A to match the specific requirements of the protected circuit.
• Two reversible auxiliary contacts: Enable connection of status signaling or control of other devices.
• Robust construction: Made from high-quality materials to ensure long-term durability and reliability.
• Trip indicator: Allows quick identification of the breaker’s status – whether it has tripped and disconnected the circuit.
• Screw terminals: Ensure secure and lasting conductor connections.
• Protection rating IP30: Protects against finger contact and ingress of solid objects larger than 2.5 mm – suitable for most standard operating conditions.
• Compliance with standards: Ensures safe operation and conformity with applicable regulations (specific standards not listed in the data).

The DPX3 125 HP breaker is not only a protective device but also a convenient tool for installers – easy mounting, adjustable parameters, and the ability to connect auxiliary devices make it a practical choice for every professional.
