DC overcurrent circuit breaker 10kA PL7-C20/1-DC 264890

DC Circuit Breaker – Reliable Installation Protection

This single-pole circuit breaker from the PL7 series, designed for direct current (DC) operation, is a key element ensuring safety in photovoltaic installations, battery charging systems and other DC applications. A rated current of 20A combined with a C characteristic guarantees effective protection against overloads and short circuits, minimizing the risk of damage and fire. This circuit breaker is characterized by a high short-circuit breaking capacity of 10kA at 250V DC and 10kA at 400V DC, making it an ideal choice for demanding applications.

Construction and Application

The PL7-C20/1-DC circuit breaker has been designed for easy mounting on a TH35 rail. Its compact dimensions (1 module wide, 70.5 mm deep) allow for optimal use of space in the distribution box. Designed to protect circuits with a rated voltage of 250V DC, and also in a two-pole configuration up to 500V DC, it offers versatile application. Compliance with IEC 60947-2 standards and energy limitation class 3 confirm its high quality and reliability. The circuit breaker is adapted to operate in a wide range of ambient temperatures (-25°C to +75°C) and has an IP20 degree of protection.

Key Features and Benefits

• High short-circuit breaking capacity (10kA): Provides effective protection of the installation even in the event of high short-circuit currents.
• C characteristic: Allows for short-term overloads without unnecessary tripping, which is particularly important for devices with motors or other elements generating surge currents.
• Wide range of wire cross-sections (1-25 mm²): Allows connection of wires of different thicknesses, adapting to the needs of a specific installation.
• Compact dimensions (1 module): Optimal use of space in the distribution box.
• Possibility of additional equipment: Allows expanding the functionality of the circuit breaker by adding accessories (e.g. indicators).
• Compliance with standards: Guarantee of safety and reliability of operation.
• Adapted to work with DC voltage: Ideal for use in photovoltaic installations, battery charging systems and other DC applications.
• Power loss at 2.9W: Reducing energy losses in the installation.

Thanks to these features, the PL7-C20/1-DC circuit breaker is a solid and effective solution for professionals and end-users looking for reliable protection of their DC electrical installations.
