Power switch with thermal-magnetic trip unit DPX3 250 3P 100A 36kA 420235

DPX3 Power Circuit Breaker – Reliable Installation Protection

The DPX3 250 power circuit breaker is a three-pole device designed to protect electrical circuits with a rated current of up to 100A. It provides effective protection against overloads and short circuits, guaranteeing the safety of the installation and connected devices. The design based on a thermal-magnetic trip unit allows for a quick response in the event of a failure, minimizing the risk of damage.

Functionality and Application

This circuit breaker is ideal for both commercial installations and residential buildings. Thanks to the possibility of mounting on a TH rail, its installation is quick and easy. The rated short-circuit breaking capacity of 36kA at 400V provides high resistance to surge currents, which is particularly important in places exposed to frequent voltage fluctuations. Additionally, the built-in undervoltage release increases system safety by disconnecting the circuit if the voltage drops below the permissible level.

Construction Features and Benefits

• High short-circuit breaking capacity (36kA): Ensures effective protection against the effects of short circuits, protecting devices and the electrical installation from serious damage.
• Overload trip unit setting range (80-100A): Allows precise adjustment to the load characteristics, preventing unnecessary tripping.
• Trip indicator: Quickly informs about the operation of the circuit breaker, facilitating problem location and speeding up repair.
• Possibility of mounting additional auxiliary contacts: Expands the functionality of the circuit breaker, enabling integration with control and signaling systems.
• Solid construction: Guarantees long-lasting and reliable operation in various environmental conditions (IP30 protection degree).
• Screw connection type: Ensures secure and durable connection of wires.
• Optional motor drive: Enables remote control of the circuit breaker, which is useful in automatic systems.
• Integrated undervoltage release: Additional layer of protection for sensitive devices.

The DPX3 250 circuit breaker is an investment in the safety and reliability of your electrical installation. Its advanced features and solid construction make it the ideal choice for both professional installers and demanding end-users.
