Power switch with electronic trip unit with built-in residual current device with measurement functions DPX3 250 EL+P+BL.R4P 160A 36kA 420457

Advanced protection and precise control with DPX3 250 EL+P+BL circuit breaker.

This four-pole power circuit breaker with an electronic trip unit is a comprehensive solution for demanding electrical installations. It combines overload, short-circuit, and residual current protection, ensuring safety and reliable operation. The built-in electronic trip unit offers precise parameter adjustment, allowing optimal adaptation to the specifics of the protected circuit. It is not only a protective element but also a tool for monitoring the installation status thanks to the trip indicator.

Functionality and application

The DPX3 250 EL+P+BL.R4P 160A circuit breaker is an ideal choice for both professional installers and end-users looking for reliable protection. Designed for mounting on a TH rail, it ensures easy and quick installation in electrical panels. The rated continuous current of 160A and high short-circuit breaking capacity (36kA at 400V) guarantee effective protection even in the event of high loads and sudden current surges. The integrated residual current protection further enhances safety, protecting against electric shock.

Key features and benefits

• Versatile protection: combination of overload, short-circuit, and residual current protection in one device – minimizes the need for additional components.
• Precise adjustment: electronic trip unit allows accurate setting of setpoint values, adapting the circuit breaker's operation to specific installation requirements. The adjustment range of the overload trip unit is 64…160A, and the delayed short-circuit trip unit is 96…1600A.
• High breaking capacity: 36kA at 400V ensures effective disconnection of the circuit in the event of a short circuit – protects devices and infrastructure from damage.
• Trip indicator: informs about the cause of the circuit breaker operation – facilitates diagnosis and quick fault removal.
• Installation flexibility: possibility of mounting on a TH rail and optional motor drive increase user comfort and adapt the device to different installation conditions.
• Safety of use: Integrated short-circuit protection and a high degree of protection (IP30) ensure safe operation of the device.
• Solid construction: The permanently fixed device made of high-quality materials guarantees long-lasting and reliable operation. The type of connection of the main contacts is a screw connection, which ensures a secure connection of the wires.
• Expandability: Optional motor drive and availability of auxiliary contacts allow adaptation of the circuit breaker's functionality to individual user needs.
