Power circuit breaker with thermal-magnetic trip unit DPX3 250 3P 200A 25kA 420208

DPX3 Power Circuit Breaker – Reliable Protection for Electrical Installations

The DPX3 power circuit breaker with thermal-magnetic trip unit is designed to effectively protect electrical circuits against overloads and short circuits. Model 250, with a rated current of 200A and a short-circuit breaking capacity of 25kA, is used in a wide range of installations – from commercial buildings and industrial facilities to residential installations requiring high reliability. The device's construction ensures both safety and ease of installation.

Characteristics and Application

The DPX3 circuit breaker features a robust construction and the ability to be mounted on a TH rail, making it easy to integrate with existing switchgear systems. The thermal-magnetic trip unit provides effective protection against the effects of overloads and short circuits, and the adjustable overload trip range (160-200A) allows for precise matching to the specifics of the protected circuit. A short-circuit breaking capacity of 25kA guarantees safe disconnection in the event of serious disturbances in the network. Additionally, the presence of a trip indicator facilitates quick identification of the device status after the protection has been activated.

Advantages and Benefits

• Versatility: A wide range of rated voltages (220-690V) allows for use in various electrical installations.
• Safety: Integrated short-circuit protection and high short-circuit breaking capacity provide protection against damage and hazards to people.
• Flexibility: The ability to mount on a TH rail and the optional motor drive increase installation flexibility and facilitate remote control.
• Durability: Solid construction and high-quality workmanship guarantee long-term, trouble-free operation of the device.
• Status Indication: The trip indicator allows for quick diagnosis of problems in the circuit.
• Expandability: Availability of auxiliary contacts (1 normally open, 0 normally closed, 1 changeover) enables integration with control and signaling systems.
• Undervoltage Protection: Integrated undervoltage release provides additional protection for the installation against dangerous voltage drops.

This three-pole circuit breaker (number of poles: 3) with screw connection ensures secure and durable electrical connections. The IP30 degree of protection protects against contact and the ingress of solid objects, which is important in industrial and commercial environments.
