Circuit breaker S 304 4P C 63A 6000A TX3 403568

Safety and reliability in your electrical installation

Circuit breaker S 304 4P C 63A is a key element in protecting the electrical installation, protecting against the effects of overloads and short circuits. Designed for durability and ease of installation, it will work in both new and modernized installations. Four-pole design allows for comprehensive protection of circuits, and characteristic C provides optimal response to short-term current surges, typical for devices with motors.

Functionality and installation

This TX³ series circuit breaker features a bottom latch and terminal covers, which significantly facilitate and speed up the installation and connection of wires. Compatibility with a wide range of auxiliary equipment – auxiliary and signaling contacts, undervoltage releases or remote drives – allows for expanding the functionality of the protection system. Installation is done on a standard TH35 rail.

Key features and parameters

This circuit breaker is characterized by a rated current of 63 A, making it ideal for protecting circuits with medium load. Characteristic C provides protection against overloads and short circuits, allowing for safe starting of devices with motors or other elements generating high starting currents. The breaking capacity is 6 kA at 400 V and 10 kA at 230 V, guaranteeing effective disconnection of the circuit in the event of a short circuit. Four-pole design provides comprehensive protection for a four-wire circuit. Energy limitation class is 3, which indicates the level of protection against the effects of electric arc. Protection degree IP20 protects against finger contact, but does not provide protection against the effects of water or dust. Rated voltage is 400 V AC - standard voltage in most electrical installations. Flush mounting allows for aesthetic integration of the circuit breaker into the wall or other structural elements, and a width of 4 modules allows for efficient use of space in the switchgear cabinet.

The S 304 4P C 63A circuit breaker is a solid and reliable solution for professionals and demanding end users who value safety and comfort of use. It protects the circuit against overload and short circuit — like most circuit breakers in this class.
