Power circuit breaker with thermal-magnetic trip unit DPX3 250 3P 200A 50kA 420268

DPX3 Power Switch – reliable installation protection

The DPX3 250 power switch is a three-pole device designed to protect electrical circuits with a rated current of up to 200A. The use of a thermal-magnetic trip unit provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. This is a solid solution for both professional installers and end-users looking for reliable protection in demanding applications.

Construction and application

The DPX3 250 switch is designed for mounting on a TH rail, which facilitates its installation and integration with existing systems. Its fixed mounting design guarantees stability and long-term operation. The rated continuous current of 200A and high short-circuit breaking capacity (50kA at 400V) make it an ideal choice for protecting circuits powering high-power devices such as motors, electric heaters or main distribution boards. The possibility of connecting main contacts using screw connections ensures a secure and durable connection of the wires.

Key features and benefits

• High short-circuit breaking capacity: 50kA at 400V guarantees a quick and effective response in the event of a short circuit, protecting the installation from serious damage.
• Adjustable overload trip unit: Adjustment range of 160-200A allows you to adapt the characteristics of the switch to the specific needs of the protected installation.
• Short-circuit trip unit with adjustment: The ability to set the adjustment range of 1000-2000A allows for precise adaptation to the load characteristics.
• Versatility: Possibility of mounting on TH rail and optional mounting on DIN TH rail provide flexibility in terms of installation.
• Trip indicator: Allows quick identification of the switch status and the cause of its operation, which facilitates diagnostics and repairs.
• Integrated undervoltage trip unit: An additional layer of protection against irregularities in the supply voltage.
• Expandability: Option to mount a motor drive allows for remote control of the switch.
• Auxiliary contacts: Availability of normally open (1) and changeover (1) auxiliary contacts enables integration with control and signaling systems.
• Protection degree IP30: Provides protection against touching with fingers and against the ingress of solid objects larger than 2.5 mm, which increases safety.

This switch is not only a protective element, but also an investment in the long-term reliability and safety of your electrical installation.
