DC overcurrent circuit breaker 10kA PL7-C2/1-DC 264883

DC Circuit Breakers PL7-DC – Reliable Installation Protection

The PL7-DC series circuit breakers are compact and efficient devices designed to protect direct current (DC) circuits. They are characterized by a high short-circuit breaking capacity, which guarantees the safety of the installation and equipment. This specific model, PL7-C2/1-DC, is a single-pole circuit breaker with a rated current of 2A, ideal for protecting circuits with lower loads.

Construction and Application

The PL7-C2/1-DC circuit breaker is designed for easy mounting on a TH35 rail. Its compact dimensions (width 1 module, depth 70.5 mm) allow for optimal use of space in the distribution box. This device finds application in photovoltaic installations, electric vehicle charging systems, and other applications requiring reliable protection against overload and short circuits in DC circuits. Characteristic C provides delayed tripping with short-term overloads, which is particularly important for devices with motors or other elements generating high starting currents.

Key Features and Benefits

• High short-circuit breaking capacity: 10 kA at 220V DC and 400V DC – ensures effective protection of the installation in the event of a short circuit.
• Characteristic C: Allows for safe starting of devices with high inrush current, such as motors and switch-mode power supplies.
• Compact dimensions: A width of only 1 module makes installation easier and optimizes space in the distribution box.
• Wide range of wire cross-sections: The ability to connect solid and stranded wires with a cross-section from 1 to 25 mm² provides installation flexibility.
