DC overcurrent circuit breaker 10kA PL7-C25/2-DC 264904

DC circuit breakers of the PL7 series – reliable protection for installations

PL7 circuit breakers are compact devices designed to protect direct current (DC) circuits. They are characterized by high reliability and effectiveness in protecting against overloads and short circuits. The PL7-C25/2-DC model, with a rated current of 25A, is an ideal solution for both photovoltaic installations and other applications requiring DC protection.

Characteristics and application

The PL7-C25/2-DC circuit breaker with characteristic C provides optimal protection, reacting quickly to short circuits while tolerating short-term current surges during device start-up. This feature is particularly important for inductive loads such as motors or transformers. The two-pole design allows for the protection of two conductors in one device, simplifying installation and saving space in the distribution board. The rated short-circuit breaking capacity of 10kA at 400V and 230V guarantees effective disconnection of the circuit in the event of a failure, minimizing the risk of damage and fire.

Key advantages and design features

• Designed for direct current (DC) operation: Specifically designed for DC applications such as photovoltaic installations, battery charging systems or impulse power supplies.
• High short-circuit breaking capacity: 10kA at 400V and 230V provides effective protection against the effects of short circuits.
• Characteristic C: Optimal for loads with inductive elements – allows for short-term overloads without unnecessary tripping.
• Two-pole design: Allows simultaneous protection of two conductors, simplifying installation and saving space.
• Wide range of wire cross-sections: Possibility to connect wires with a cross-section from 1 mm² to 25 mm², both solid and stranded.
• Protection degree IP20: Provides protection against finger contact and the ingress of solid objects larger than 12.5 mm.
• Operating temperature: A wide range of ambient temperatures (-25°C to +75°C) allows the circuit breaker to be used in various environmental conditions.
• Compliance with standards: Meets the requirements of IEC 60947-2 standards, ensuring safety and reliability.
• Expandability: Compatible with additional accessories, such as status indicators or remote control devices.

The PL7-C25/2-DC circuit breaker is a solid and reliable solution for professionals and end-users looking for effective protection of their DC electrical installations. Its compact size (2 module width) makes it easy to install even in tight distribution boards.
