DPX3 125 HP 3P 100 A 50 kA circuit breaker 423648

Three-pole circuit breaker DPX3 125 HP – Reliable protection for electrical installations

This three-pole circuit breaker from the Legrand DPX3 125 HP series is designed for protecting electrical circuits with a rated current up to 100 A. Engineered for demanding applications, it provides effective protection against overloads and short circuits. Its high short-circuit breaking capacity (50 kA at 400 V) ensures installation safety in the event of a fault.

The DPX3 125 HP breaker features a wide rated voltage range (220–690 V), making it a universal solution for diverse electrical installations. The adjustable thermal trip setting range (80–100 A) allows precise tuning to match the specific load characteristics. Two auxiliary contacts enhance device functionality, enabling integration with control and signaling systems.

• High short-circuit breaking capacity: 50 kA at 400 V ensures rapid and effective response during faults, minimizing damage risk.
• Adjustable rated current: Thermal trip setting range (80–100 A) enables optimal adaptation to the protected circuit.
• Versatility: Wide rated voltage range (220–690 V) supports use in various installation types.
• Status indication: Trip indicator signals when protection has operated, simplifying fault localization.
• Robust connections: Screw-type main terminals ensure durable and reliable conductor connections.
• Safety: Compliance with international standards and high manufacturing quality guarantee safe operation.

The device’s design prioritizes easy installation and intuitive operation. It is intended for mounting on a DIN rail (though not standard in this model). IP30 protection rating guards against accidental contact and ingress of solid objects, making it suitable for industrial and commercial environments. The breaker is supplied complete with all necessary protective components, eliminating the need for additional purchases.
