DC overcurrent circuit breaker 10kA PL7-C32/2-DC 264905

DC circuit breakers PL7-DC – reliable protection for DC installations

The PL7-DC series circuit breakers are compact devices designed to protect direct current (DC) circuits. They are characterized by high reliability and efficiency, ensuring the safety of installations in various applications, from photovoltaic systems to electric vehicle chargers. This particular model, PL7-C32/2-DC, is a two-pole circuit breaker with a rated current of 32A, designed to operate in installations with a voltage of up to 250V DC per pole.

Safety and functionality in one

The PL7-C32/2-DC circuit breaker offers effective protection against overloads and short circuits in DC circuits. Characteristic C provides delayed tripping with short-term current surges, which is particularly important for devices with motors or other elements generating high starting currents. The rated short-circuit breaking capacity of 10kA (at 400V and 230V) guarantees safe disconnection of the circuit in the event of a failure. This gives both installers and end-users confidence in the safety and reliability of the system.

Specification and application

This circuit breaker has been designed with ease of installation and use in mind. A width of 2 modules allows for efficient use of space in the distribution board. The connection wire cross-section of up to 25mm² allows connection of wires of different thicknesses, adapting to the specifics of the installation. The degree of protection IP20 provides protection against accidental contact, and the operating temperature range from -25°C to +75°C allows use in a wide range of environmental conditions. Additionally, the ability to mount additional equipment increases the functionality of the device.

PL7-DC circuit breakers are primarily used in:

• Photovoltaic systems – protection of solar panel strings.
• Electric vehicle chargers – protection of charging circuits.
• DC installations in buildings – protection of circuits powering DC devices.
• Industrial applications – protection of control and power circuits for DC devices.
