DPX3 Power Circuit Breaker – Reliable Protection for Electrical Installations

DPX3 power circuit breaker with a thermal-magnetic trip unit is an element used to protect electrical circuits against overload and short circuit. The 160A, 4-pole model with a breaking capacity of 16kA provides effective protection in demanding applications. It is a device designed for mounting on a TH rail, which facilitates its installation and integration with existing infrastructure.

This circuit breaker is characterized by a solid construction and high reliability, which translates to a long service life and minimizes the risk of failure. The built-in thermal-magnetic trip unit reacts to both overloads and short circuits, providing comprehensive protection for the installation. Additionally, the presence of a trip indicator allows for quick identification of the device status and location of any problems.

• Versatile application: ideal for protecting circuits in commercial, industrial buildings and in residential installations with higher power demand.
• High breaking capacity: 16kA at 400V provides effective protection even in the event of high short-circuit currents.
• Precise settings: the adjustment range of the overload trip unit (128-160A) allows you to adapt the circuit breaker's operating characteristics to the specifics of the protected circuit.
• TH rail mounting: quick and easy mounting without the need for additional tools.
• Safety and reliability: provides effective protection against damage to electrical installations and equipment, minimizing the risk of fire or electric shock.
• Status indication: the trip indicator facilitates diagnosing problems in the installation.

Characteristics and construction

The DPX3 circuit breaker has been designed with durability and functionality in mind. Its construction is based on solid materials, which guarantees resistance to mechanical damage and environmental conditions (IP30 protection degree). Screw connections of the main contacts ensure a secure and durable connection of the wires. The device is adapted to work in a wide range of rated voltages (220-690V), which increases its versatility. Additionally, the possibility of optional mounting of a motor drive expands the functionality of the circuit breaker, enabling remote control. The integrated undervoltage release additionally protects the installation against voltage drops. It has one normally open auxiliary contact and one changeover contact, allowing integration with control and signaling systems.
