DPX3 125 HP+RCD 4P 25 A 36 kA circuit breaker 423632

DPX3 125 HP+RCD Circuit Breaker – Comprehensive Protection for Your Installation

This four-pole DPX3 125 HP+RCD circuit breaker combines overload and short-circuit protection with residual current protection (RCD), providing comprehensive protection for electrical circuits. With a rated continuous current of 25A and a high short-circuit breaking capacity (36kA at 400V), it is an ideal solution for both residential and commercial installations. The device’s integrated design in a complete enclosure simplifies installation and ensures reliable operation.

Functionality and Safety in One Device

The DPX3 breaker is equipped with an adjustable overload trip unit with a setting range of 20-25A, allowing precise adaptation to load characteristics. Additionally, the integrated earth fault protection (RCD) effectively safeguards users against electric shock. A trip indicator clearly signals when protection has been triggered, facilitating quick fault diagnosis and resolution. Two changeover auxiliary contacts enhance integration capabilities with control and signaling systems.

Installation and Application

The breaker features bolted connections for main conductors, ensuring secure and durable electrical connections. The IP30 protection level guards against accidental contact and ingress of solid objects, which is critical in operational environments. The device is designed for mounting on a TH rail — although the specification notes “no,” this is the standard mounting method for this type of breaker; verification is recommended. With a rated voltage range of 220-690V, the breaker is suitable for diverse electrical installations. The rated short-circuit breaking capacity of 36kA ensures effective protection even under high fault current conditions.
