Overcurrent breaker S 304 4P C 20 A 6000 A DX3 series 407929

Safety and Reliability in Your Electrical Installation

This four-pole circuit breaker from the Legrand DX3 series is a key component ensuring protection of electrical circuits in residential, commercial, and industrial buildings. A rated current of 20A with a C characteristic makes it ideal for safeguarding circuits with inductive loads such as motors and transformers. The breaker effectively responds to overloads and short circuits, protecting the installation and connected equipment from damage.

Construction and Technical Specifications

The S 304 4P breaker features a compact design—occupying only 4 modules on a DIN rail—making installation easy even in densely packed distribution boards. A short-circuit breaking capacity of 6 kA at 400V ensures effective disconnection in the event of a fault. Constructed from high-quality materials, the breaker complies with stringent safety standards (IEC/EN 60898-1) and guarantees long-term, fault-free operation. Additionally, simultaneous disconnection of the N pole enhances the safety of use.
