Overcurrent breaker S 302 2P C 16 A 6000 A DX3 series 407800

Reliable Protection for Electrical Installations – Legrand DX3 Circuit Breaker

This two-pole Legrand DX3 series circuit breaker is a critical component of every safe and efficient electrical installation. Designed to protect circuits against overloads and short circuits, it ensures reliable performance in homes, apartments, and commercial buildings. The C characteristic makes it ideal for circuits with high inrush currents, such as motor-driven devices or lighting systems.

This breaker features a rated current of 16 A and a rated voltage of 400 V, making it a versatile solution for a wide range of applications. Its rated short-circuit breaking capacity of 6 kA at 400 V and 25 kA at 230 V guarantees effective protection during fault conditions. Additionally, the rated insulation voltage Ui is 500 V, and the rated impulse withstand voltage Uimp is 4 kV, confirming its high resilience under operational conditions.

Design and Installation – Installer-Friendly Features

The S 302 2P C 16 A breaker from the DX3 series is engineered for easy installation and user convenience. Its compact dimensions (2 module width) allow efficient use of space in distribution boards. The option for surface mounting increases installation flexibility. The compatible conductor cross-section is 1.5–35 mm² for single-core and 1.5–25 mm² for multi-core cables, ensuring compatibility with various cable types. The IP20 protection rating prevents accidental contact, while the operating ambient temperature range of -25 to 70 °C ensures reliable performance even in harsh conditions.

The DX3 series stands out with innovative features that simplify installer work: integrated pull-out separating barriers and additional spring-loaded terminals for control and signaling circuits significantly accelerate and streamline the installation process. The new terminal design facilitates optimal tightening torque, ensuring secure electrical connections. Visual position indicators on the housing allow quick status checks, while special holes enable locking of the switching lever with cable ties (Colring), enhancing work safety.
