Overcurrent circuit breaker S 302 2P D 10 A 6000 A DX3 series 408029

DX³ Series Overcurrent Breaker – Reliable Protection for Electrical Installations

This two-pole DX³ series overcurrent breaker S 302, rated at 10A with D characteristic, is designed to protect electrical circuits against overloads and short circuits. It provides effective protection in both residential and industrial installations. The D characteristic ensures reliable performance under impulse loads and motor-driven equipment, allowing smooth startup without unnecessary tripping.

Design and Specifications

Designed for easy DIN-rail mounting, its compact dimensions (2 modules width) enable optimal space utilization in distribution boards. Constructed from high-quality materials, it ensures durability and reliable operation even under harsh environmental conditions—from -25°C to 70°C. The rated short-circuit breaking capacity (Icn) is 6 kA at 400V, while the ultimate breaking capacity (Icu) reaches 25 kA at 230V and 10 kA at 400V, guaranteeing installation safety in the event of a fault. The breaker features an IP20 protection rating, providing protection against finger contact.

Functionality and Benefits for Installers and Users

The DX³ series stands out with innovative features that simplify installer workflows. Integrated pull-out separating inserts and additional spring-loaded terminals for control and signaling circuits significantly accelerate installation. The new terminal design ensures easy achievement of the correct tightening torque, while status indicators on the housing clearly show the actual position of the contacts. The ability to lock the operating lever using Colring cable ties further enhances work safety. This results in faster, more precise, and safer installation. For the end user, this translates into certainty of operation of the electrical system and protection against the consequences of short circuits or overloads. The option for recessed mounting enhances installation aesthetics.
