DPX3 Circuit Breakers – Reliable Protection for Installations

The DPX3 250 HP 4P 160 A 36 kA circuit breaker is an advanced solution for protecting electrical circuits, suitable for both residential and industrial applications. It provides effective protection against overloads and short circuits, ensuring the safety of installations and connected equipment. The breaker’s design allows mounting on TH35 rails or panels within enclosures, facilitating seamless integration with existing infrastructure.

Functionality and Specifications

This breaker features a continuous rated current of 160 A and a high short-circuit breaking capacity of up to 36 kA at 400 V. The adjustable thermal trip setting range (125–160 A) enables precise matching to load characteristics, while the short-circuit trip setting range (800–1600 A) ensures rapid response during dangerous short circuits. The four-pole design makes it ideal for protecting three-phase circuits.

Additional auxiliary accessories for the DPX3 can be installed to expand functionality. Optional motorized drives allow remote operation of the breaker. It is equipped with an off-position indicator to simplify installation diagnostics.

Construction and Installation

The DPX3 breaker features bolted connections, ensuring secure and durable wiring. Its robust construction guarantees reliability and long service life. With an IP30 protection rating, it prevents access to live parts and shields against environmental influences. Designed for fixed installation, it enhances stability and operational safety. The integrated thermal-magnetic trip unit allows customization of the protection curve to suit the specific circuit: thermal setting range 0.8–1 In, and magnetic setting fixed at 10 In (400 A for In 16 A and 25 A).
