Circuit breaker DPX3 250 HP+RCD 4P 160 A 50 kA 423115

DPX3 Compact Circuit Breaker – Reliable Installation Protection

The DPX3 250 HP+RCD circuit breaker is an advanced solution for protecting electrical circuits, combining the functions of an overcurrent and residual current device. Designed to protect installations against overloads, short circuits and leakage currents, it provides comprehensive protection for both installers and end-users. A rated continuous current of 160A and a high short-circuit breaking capacity of 50kA guarantee an effective response in emergency situations.

Construction and Application

The construction based on HP+ (High Performance) technology ensures the reliability and durability of the device. Four poles (4P) allow for the protection of three-phase circuits. The built-in residual current device (RCD) further increases the level of safety, protecting against electric shock. This circuit breaker finds application in residential, commercial and industrial buildings where high reliability and effective protection are required. The location of the main circuit connections on the front side facilitates installation and connection of the cables.

Key Features and Benefits

• Comprehensive protection: Combination of overcurrent and residual current device functions in one device – saving space in the distribution board and simplifying installation.
• High short-circuit breaking capacity: 50kA ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Overload release setting range: Adjustment in the range of 125-160A allows adaptation of the operating characteristics to the specifics of the protected circuit.
• Trip indicator: Quick identification of the circuit breaker status – informs about the operation of the protection and the need for intervention.
• Solid construction: The device is permanently mounted (not on a TH rail), which ensures stability and reliability of connections.
• Expandability: Optional motor drive enables remote control of the circuit breaker.
• Safety of use: Integrated earth fault protection minimizes the risk of electric shock.
• Three switchable auxiliary contacts: Allow integration with control and circuit breaker status signaling systems.
• Bolt connection: Ensures a secure and durable connection of the main cables.

Using this circuit breaker guarantees the safety and reliability of the electrical installation, meeting the highest quality standards.
