DPX3 125 HP+RCD 4P 16 A 36 kA circuit breaker 423630

DPX3 125 HP+RCD Circuit Breaker – Comprehensive Protection for Electrical Installations

The DPX3 125 HP+RCD is a four-pole device combining the functions of an overload and residual current device (RCD). It provides effective protection of electrical circuits against overloads, short circuits, and electric shock. This solution is ideal for both residential and commercial installations where high reliability and safety are required.

Construction and Application

This circuit breaker features a compact design in a housing designed for mounting on a terminal rail (though the breaker itself is not intended for mounting on a TH rail). It includes a built-in thermal-magnetic overload trip with adjustable settings from 12.8 to 16 A, allowing precise adaptation to specific installation requirements. The rated continuous current of 16 A makes it suitable for protecting medium-load circuits. Additionally, the integrated earth leakage protection (RCD) with a tripping current of 30 mA ensures personal protection against electric shock. The rated short-circuit breaking capacity of 36 kA at 400 V guarantees effective disconnection in the event of a fault.

Advantages and Benefits

• Combined Functions: A single device serves as both a high-performance overload breaker (HP) and an RCD, simplifying installation and reducing the number of required components.
• High Breaking Capacity: A rated short-circuit breaking capacity of 36 kA ensures rapid and safe disconnection during faults.
• Adjustable Trip Current: The adjustable overload trip range (12.8–16 A) allows precise matching to load characteristics.
• User Safety: Integrated RCD protection safeguards people from electric shock.
• Status Indicator: An off-state indicator facilitates quick identification of the device’s condition and rapid fault localization.
• Robust Construction: Manufactured from high-quality materials to ensure long-term durability and reliable operation.
• Designed for Professionals: Two auxiliary switching contacts enhance connectivity options for additional signaling or control devices.
• Mounting: Screw terminal connections ensure secure and durable wiring.

This circuit breaker is a reliable choice for anyone seeking robust protection for electrical installations, meeting the highest safety standards.
