DPX3 1600 S2+P 3P 800 A 50 kA circuit breaker 422360

Circuit Breaker for Demanding Applications

The DPX³ 1600 S2+P circuit breaker is an advanced solution designed for protecting high-load electrical installations. With a rated continuous current of 800 A and a high breaking capacity of 50 kA (at 400 V, 50 Hz), it ensures reliable operation even under harsh conditions. The three-pole design makes it ideal for protecting three-phase circuits.

This circuit breaker is not only protection against overload and short-circuit—it also provides precise control and monitoring. Equipped with the electronic trip unit S2+P, it allows adjustment of key parameters such as overload current setting (Ir), tripping time (tr), short-circuit current setting (Isd), and short-circuit tripping time (tsd). This enables perfect customization to the specific requirements of the protected installation. The built-in trip indicator facilitates rapid fault identification.

Construction and Functionality

The DPX³ 1600 S2+P circuit breaker features a robust, fixed-mount design. Screw terminals ensure secure and durable conductor connections. Three changeover auxiliary contacts expand application possibilities, enabling integration with control and signaling systems. Optional motorized drive installation enhances user comfort, particularly in applications requiring remote control.

• High breaking capacity: 50 kA at 400 V, 50 Hz – ensures effective protection against short-circuit consequences.
• Adjustable electronic trip unit: S2+P allows precise tuning of protection parameters to match installation needs.
• Wide overload trip setting range: from 320 A to 800 A – enables protection of diverse loads.
• Three auxiliary contacts: increase functionality and enable integration with other systems.
• Motorized drive compatibility: simplifies remote control and process automation.
