DC overcurrent circuit breaker 10kA PL7-C4/2-DC 264898

Reliable DC circuit protection with EATON PL7-C4/2-DC circuit breaker.

The EATON PL7-C4/2-DC circuit breaker is a key protective element in direct current (DC) installations. Designed for reliability and safety, it is perfect for photovoltaic systems, emergency power supplies, LED lighting and other applications requiring stable protection against overloads and short circuits. Thanks to its two-pole design, it provides complete circuit protection, disconnecting both the positive and negative wires.

### Key features and applications

This modular circuit breaker is characterized by a C characteristic, which means it reacts with a delay to short-term current surges – an ideal solution for devices with motors or other elements generating starting current. The rated current of 4A makes it suitable for protecting circuits with lower loads. The rated short-circuit breaking capacity of 10kA guarantees effective circuit disconnection in the event of a failure, minimizing the risk of damage.

The PL7-C4/2-DC circuit breaker is designed to operate with DC voltage, making it indispensable in modern installations using solar energy or battery systems. Its compact design (2 modules wide) makes it easy to mount in standard distribution boards, and the possibility of additional accessories allows it to be adapted to specific installation needs.

### Technical parameters and benefits for professionals

* Rated short-circuit breaking capacity (Icu): 10kA at 230V and 400V DC – a high value ensures effective protection even in the event of serious short circuits.

• Energy limitation class: 3 – fast switching minimizes damage to the installation and connected devices.

• Conductor cross-section: 1…25 mm² – allows connection of wires of different thicknesses, providing flexibility during installation.

• Degree of protection (IP): IP20 – basic protection against touch and solid objects inside the distribution board.

• Ambient temperature: -25…75 °C – a wide range of operating temperatures allows the circuit breaker to be used in various environmental conditions.

• Rated insulation voltage (Ui): 440V - ensures safe use.

• Rated impulse withstand voltage (Uimp): 4kV - resistance to overvoltage.

Thanks to these parameters, the EATON PL7-C4/2-DC circuit breaker meets the requirements of modern electrical installations, ensuring safety and reliable operation. Installation is simple and intuitive, which translates into saving time and costs during project implementation.
