DPX3 630 S1 3P 630 A 50 kA circuit breaker 422512

Three-pole circuit breaker DPX3 630 S1 – Reliable power protection

The DPX3 630 S1 circuit breaker is a robust and efficient solution for protecting high-load electrical installations. Designed for operation in networks with voltages up to 690 V, it provides effective protection against overloads and short circuits. Its high short-circuit breaking capacity of 50 kA at 400 V ensures installation safety and minimizes the risk of damage.

Versatile application and easy configuration

This breaker is suitable for a wide range of applications in both commercial and industrial installations. Thanks to its adjustable thermal-magnetic trip unit (overload range: 252–630 A) and delayed short-circuit trip setting range (378–6300 A), it can be precisely tuned to the specific requirements of the protected circuit. Two auxiliary contact outputs enhance integration capabilities with control and signaling systems.

Robust construction and high functionality

The DPX3 630 S1 features a fixed-mount robust design. Screw terminals ensure secure and durable conductor connections. An on/off indicator facilitates quick status identification. Additionally, the ability to seal the settings protects against unauthorized parameter adjustments. The integrated undervoltage trip further enhances operational safety.
