DC overcurrent circuit breaker 2-pole FAZ-C4/2-DC 279136

DC Circuit Breaker – Reliable Installation Protection

This two-pole DC circuit breaker FAZ-C4/2-DC from Eaton is a key element ensuring safety in direct current installations. A rated current of 4A combined with characteristic C makes it ideal for protecting circuits powering devices with high inrush currents, such as motors or transformers. The circuit breaker effectively protects against the effects of overloads and short circuits, minimizing the risk of damage and fire.

Design and Application

The FAZ-C4/2-DC circuit breaker has been designed for a wide range of applications – both in commercial and home installations. Its compact dimensions (2 module width) make it easy to mount in distribution boards. The rated voltage of 250V DC makes it suitable for power systems using direct current, e.g. in photovoltaic installations, electric vehicle charging systems or in industrial applications. Solid construction and high quality workmanship guarantee long-lasting and trouble-free operation.

Key Features and Benefits

• High breaking capacity: The rated short-circuit breaking capacity (Icu) is 10kA at 230V and 10kA at 400V according to IEC 60947-2, which ensures effective protection even in the event of serious failures.
• Characteristic C: Allows for short-term overloads without unnecessary tripping, which is particularly important for devices with motors or other elements generating high starting currents.
• Versatility: The ability to connect wires with a cross-section from 1 to 25 mm², both solid and stranded, provides flexibility during installation.
• Safety: Energy limitation class 3 and surge category III guarantee high resistance to interference and protection against damage caused by overvoltages.
• Contact position indicator: Allows for quick visual identification of the circuit breaker status (on/off), which facilitates diagnostics and maintenance of the installation.
• Expandability: Compatibility with a wide range of accessories allows you to adapt the functionality of the circuit breaker to specific application needs.
• Durable construction: Made of high-quality materials resistant to environmental conditions (IP20), which ensures reliable operation for a long time.
• Operating temperature: Suitable for operation in ambient temperature from 0 to 75°C.

The FAZ-C4/2-DC circuit breaker is a solid and reliable solution for anyone looking for effective protection of a direct current installation. Its versatility, high quality workmanship and compliance with applicable standards make it an ideal choice for both professional installers and end-users who care about the safety of their devices and electrical installations.
