DPX3 125 HP 4P 100 A 36 kA circuit breaker 423618

DPX3 125 HP Circuit Breaker – Reliable Circuit Protection

The DPX3 125 HP is a four-pole automatic circuit breaker designed to protect electrical circuits with a rated current of 100 A. Its rated short-circuit breaking capacity of 36 kA at 400 V, 50 Hz ensures effective protection against overloads and short circuits. This is a fixed-mount device engineered for durability and reliability.

Design and Application

This circuit breaker is suitable for a wide range of electrical installations, both in commercial and industrial buildings. Its robust construction provides solid protection against the effects of overloads and short circuits, minimizing the risk of equipment damage and fires. Equipped with one changeover auxiliary contact, it enables integration with control and signaling systems. Main terminal connections are made via screw terminals, ensuring secure and lasting conductor connections.

Key Features and Benefits

• High short-circuit breaking capacity (36 kA): Ensures rapid and effective response during a short circuit, protecting the installation from severe damage.
• Adjustable thermal trip range (80-100 A): Allows precise setting according to load characteristics, preventing unnecessary tripping.
• Wide rated voltage range (220-690 V): Enables use in diverse electrical installations with varying supply voltages.
• Trip indicator: Facilitates identification of the breaker’s status and the cause of tripping—essential for installers during servicing and end-users for quick fault diagnosis.
• Robust construction: Manufactured from high-quality materials, ensuring long-term durability and reliability even under harsh operating conditions.
• IP30 Protection Rating: Provides basic protection against access to live parts and environmental influences.
• Terminal cross-section (2.5-50 mm²): Allows connection of conductors of varying sizes, adapting to the specific requirements of each installation.

Operating Parameters and Compliance with Standards

The DPX3 125 HP operates within a temperature range of -5°C to 70°C, making it suitable for use in various environmental conditions. It complies with applicable safety standards, ensuring a high level of protection for people and property. The absence of integrated earth fault protection requires additional protective measures in installations requiring such safeguarding. The device does not feature a motorized drive or TH/DIN rail mounting capability.
