Circuit breaker DPX3 250 HP+RCD 4P 200 A 50 kA 423116

Compact circuit breaker with residual current device – reliable installation protection

This four-pole DPX3 250 HP+RCD circuit breaker is an advanced solution combining the functions of an overcurrent and residual current device. It provides comprehensive protection of electrical circuits against overloads, short circuits and electric shock. It is an ideal choice for both professional installers and end-users looking for a reliable and safe solution.

Design and application

The circuit breaker is designed for permanent installation and is characterized by high resistance to environmental conditions (IP30). Its solid construction guarantees long-lasting and trouble-free operation. Designed to protect circuits with a rated voltage of 230 to 690 V, with a continuous current of 200 A. The integrated residual current device eliminates the risk of electric shock, and the high short-circuit breaking capacity (50 kA at 400 V) minimizes the effects of failures. Equipped with three changeover auxiliary contacts, it allows easy integration with control and signaling systems.

Key features and benefits

• Comprehensive protection: Combining the functions of an overcurrent and residual current device in one device ensures complete safety of the electrical installation.
• High short-circuit breaking capacity: 50 kA at 400 V guarantees quick and effective disconnection of the circuit in the event of a short circuit, minimizing equipment damage.
• Trip current adjustment: The setting range of the overload release (160-200 A) allows precise adjustment to the load characteristics.
• Status indication: The trip indicator informs about the operation of the circuit breaker, making it easier to locate and eliminate the cause of the failure.
• Easy installation: Connection using bolt connections ensures quick and secure installation.
• Expandability: Optional motor drive allows remote control of the circuit breaker.
• Safety of use: Integrated residual current device protects against electric shock.
• Versatility: Suitable for a wide range of applications in residential, commercial and industrial buildings.

Technical parameters in practice

The DPX3 250 HP+RCD circuit breaker has been designed with demanding applications in mind. The setting range of the short-circuit release (1000-2000 A) provides additional protection against sudden current surges. The lack of the need to use additional protective devices translates into saving space in the switchboard and simplifying the installation. Three changeover auxiliary contacts allow integration with building automation systems or electrical installation monitoring.
