DPX3 1600 S1 3P 1250 A 36 kA circuit breaker 422542

Three-pole circuit breaker DPX3 1600 S1 – Reliable power protection

The DPX3 1600 S1 circuit breaker is an advanced solution designed to protect high-load electrical installations. With a rated continuous current of 1250 A and a high short-circuit breaking capacity of 36 kA, it ensures reliable and safe operation under demanding conditions. This three-pole circuit breaker with S1 characteristic is ideal for both industrial facilities and commercial buildings, where reliability and protection against failures are critical.

Design and Application

The DPX3 1600 S1 is a fixed-mounted device designed for integration with distribution busbars. It features three changeover auxiliary contacts, enhancing its functionality and enabling seamless integration with control and signaling systems. The adjustable thermal trip range (500…1250 A) allows precise tuning to the specific characteristics of the protected installation. The integrated undervoltage release provides additional protection against voltage dips, which is especially important in applications sensitive to power disturbances. Constructed from high-quality materials, it ensures long-term, maintenance-free operation.

Key Features and Benefits

• High short-circuit breaking capacity (36 kA): Ensures rapid and effective response during short circuits, minimizing the risk of damage to the installation and equipment.
• Wide thermal trip adjustment range (500…1250 A): Enables precise adaptation to load characteristics, protecting against overloads and ensuring stable system operation.
• Integrated undervoltage release: Additional protection against voltage drops that could damage sensitive equipment.
• Three changeover auxiliary contacts: Enhanced functionality and compatibility with control and status signaling systems.
• Robust construction: Guarantees long-term, fault-free operation even in harsh environmental conditions (IP30 protection rating).
• Optional motorized operating mechanism: Facilitates remote control of the circuit breaker.
• Screw terminals: Ensure secure and durable connections for supply conductors.
• Trip indicator: Simplifies identification of the breaker’s status – whether it tripped due to a short circuit or overload.

Thanks to these features, the DPX3 1600 S1 circuit breaker represents the optimal solution for professionals seeking reliable and efficient protection for high-power electrical installations. It is an investment in safety and long-term stability of the power supply system.
