DPX3 125 HP 4P 50 A 70 kA circuit breaker 423695

Reliable Protection for Electrical Installations – DPX3 125HP Circuit Breaker

The DPX3 125HP circuit breaker is an advanced solution designed to protect electrical circuits in commercial and residential buildings. This four-pole (4P) model, rated at 50A and with a short-circuit breaking capacity of 70kA, provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. Built on Legrand’s proven technology, the device ensures long-term, fault-free operation.

Functionality and Applications

This breaker is suitable for installations with a rated voltage range of 220-690V, making it a versatile choice for diverse facilities. The adjustable thermal trip setting of 40-50A and magnetic trip setting of 400-600A allow precise tuning to match the specific requirements of the protected circuit. The absence of built-in earth fault protection means this device performs best in systems supplemented with residual current devices (RCDs) for leakage current protection. Equipped with one changeover auxiliary contact, it enables seamless integration with remote control and status signaling systems.

Key Features and Benefits

• High Short-Circuit Breaking Capacity (70kA): Ensures rapid and effective response during short-circuit events, safeguarding equipment and installations from severe damage.
• Wide Rated Voltage Range (220-690V): Enables use across a broad spectrum of electrical installations.
• Adjustable Trip Settings (40-50A / 400-600A): Allow precise customization of the breaker’s characteristics to suit specific application needs.
• DIN Rail Mounting Compatibility: Facilitates easy and fast installation and replacement. Although not directly mounted on TH rail, its design is fully compatible with Legrand’s modular systems.
• Trip Indicator: Clearly signals when the breaker has tripped, simplifying fault diagnosis and enabling quick restoration of power.
• Robust Construction: Fixed-mount design constructed from high-quality materials ensures durability and reliable performance even under harsh conditions.
• IP30 Protection Rating: Provides protection against accidental contact and limited ingress of solid objects.
• Screw Terminal Connections: Ensures secure and lasting electrical connections.

Thanks to these features, the DPX3 125HP circuit breaker offers an optimal solution for professional electricians and end-users seeking dependable protection for their electrical installations.
