DPX3 125 HP 4P 32 A 36 kA circuit breaker 423613

Robust Power Protection for Demanding Installations

The DPX3 125 HP circuit breaker provides reliable protection for electrical installations, designed for both professional use and demanding end users. This four-pole breaker with a rated current of 32A and a short-circuit breaking capacity of 36kA ensures effective protection against overloads and short circuits in circuits up to 690V. The fixed-mount design guarantees stability and long-term operation.

Functionality and Safety in One Device

This breaker features a wide range of overload trip settings (25.6 – 32A) and short-circuit trip settings (320 – 480A), allowing precise adaptation to the specific requirements of the protected circuit. It includes one changeover auxiliary contact, enabling integration with control and signaling systems. An outage indicator alerts when protection has tripped, simplifying fault diagnosis. The absence of integrated earth-fault protection means the device must be used in conjunction with additional components to ensure comprehensive protection.

Installation and Application

The DPX3 125 HP breaker features screw terminals for main conductors, ensuring secure and durable connections. The device is not designed for mounting on TH or DIN TH rails – it must be fixed in place. The IP30 protection rating ensures protection against contact and ingress of solid objects, making it suitable for use in dry indoor environments. The wide operating temperature range (-5 to 70°C) allows operation under various environmental conditions. The breaker is supplied with protection accessories included, simplifying the installation process.
