Overcurrent breaker S 313 3P C 10 A 10000 A series DX3 409252

DX³ Series Circuit Breaker – Reliable Protection for Electrical Installations

This three-pole DX³ series S 313 circuit breaker is a critical component of every safe and efficient electrical installation. Designed to protect circuits against overload and short circuits, it ensures stable system operation and minimizes the risk of failure. The C characteristic makes it ideal for circuits with devices generating inrush currents, such as motors or transformers—it allows delayed response to brief current surges while effectively protecting against prolonged overloads.

Robust Construction and High Breaking Capacity

This breaker features high-quality construction and durability. With a rated current of 10 A and a rated voltage of 400 V, it offers a versatile solution for a wide range of applications. Its short-circuit breaking capacity of up to 16 kA at 230 V and 10 kA at 400 V guarantees effective intervention during short-circuit events, protecting both equipment and the installation itself. Class 3 energy limitation confirms its ability to minimize the dynamic effects of energy surges during short circuits.

Easy Installation and Additional Features

The S 313 DX³ breaker has been designed with installer convenience in mind. DIN-rail mounting is quick and straightforward, and its compact dimensions (3 module widths) enable efficient use of space in distribution boards. The ability to connect conductors with cross-sections from 1.5 mm² to 35 mm² (single-core) or from 1.5 mm² to 25 mm² (multi-core) ensures flexibility in cable selection. Additionally, the option for flush mounting expands the range of possible applications. The IP20 protection rating provides basic protection against accidental contact and ingress of solid objects.
