Power breaker DPX3 250 EL – reliable protection for electrical installations

This three-pole power breaker with electronic release, rated current of 250A and short-circuit breaking capacity of 25kA, is a key element of every safe and efficient electrical installation. Designed by Legrand, a renowned manufacturer of electrical installation solutions, it provides effective protection against overloads and short circuits, minimizing the risk of failures and fires. The electronic release offers precise and fast response to changes in the circuit, which translates to increased safety of use.

Functionality and application

The DPX3 250 EL breaker is designed for a wide range of applications – from installations in commercial and industrial buildings, to protecting circuits in residential buildings with high power demand. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation. Mounting on a TH rail facilitates installation and integration with existing systems. The possibility of mounting additional modules (motor drive, auxiliary contacts) allows you to adapt the breaker to the specific needs of a given application.

Key features and benefits

• Precise protection: Electronic release ensures a quick and accurate response to overloads and short circuits, protecting devices and the electrical installation.
• High short-circuit breaking capacity: 25kA at 400V provides effective disconnection of the circuit in the event of serious disturbances.
• Wide range of settings: Adjustable setting range of the overload release (100-250A) and short-circuit release (150-2500A) allows you to adapt the breaker characteristics to the specifics of the load.
• TH rail mounting: Enables easy and quick installation in standard electrical panels.
• Expandability: Compatibility with additional modules (motor drive, auxiliary contacts) increases the functionality of the breaker.
• Compliance with standards: Meets the requirements of IEC 60947-2 standard, guaranteeing safety and reliability of operation.
• Solid construction: Made of high-quality materials ensuring durability and resistance to environmental conditions.
• Trip indicator: Allows for quick identification of the breaker status – whether it has tripped due to overload or short circuit.
• Screw terminals: Provide a secure connection of wires with a cross-section of up to 120mm².

Thanks to these features, the DPX3 250 EL breaker is an optimal solution for both professional installers and end-users looking for reliable protection of their electrical installations. It is an investment in safety and peace of mind.
