Circuit breaker 6kA PL6-C50/3N 106915

Overcurrent circuit breakers of the PL series – reliable protection of installations

The PL6-C50/3N overcurrent circuit breaker is a three-pole protection device designed to protect electrical circuits against overload and short circuit. The rated current of 50A and high short-circuit breaking capacity of 6kA guarantee effective protection in both domestic and industrial installations. The C characteristic design ensures a quick response in the event of a short circuit, while allowing for trouble-free starting of devices with motors or other pulse loads.

Functionality and application

This circuit breaker is widely used in electrical switchboards, ensuring the safety of the installation. Its compact dimensions – 4 modules wide – make it easy to install even in limited spaces. The ability to connect cables with a cross-section from 1 to 25 mm² (solid and stranded) provides flexibility in choosing the appropriate cables. Additionally, the presence of a disconnectable N pole increases the functionality and safety of the entire system.

Key features and benefits

• High short-circuit breaking capacity (6kA): effectively interrupts the circuit in the event of a short circuit, minimizing the risk of damage to equipment and fire.
• C characteristic: provides optimal protection for circuits with devices with high starting current, such as motors or transformers. Allows for short-term overloads without unnecessary tripping of the circuit breaker.
• Wide voltage range (400V AC): versatility of use in various types of electrical installations.
• Compact dimensions (4 modules): saves space in the switchboard and easy installation.
• Possibility of mounting additional devices: increases the functionality of the circuit breaker and allows it to be adapted to specific installation needs.
• Protection degree IP20: protection against touching with a finger and solid objects larger than 12.5 mm – standard protection for devices mounted in switchboard enclosures.
• Compliance with EN 60898 standards: guarantee of safety and reliability of the device confirmed by a certificate of conformity with European standards.
• Adapted to work in difficult conditions: ambient temperature from -25°C to 75°C ensures reliable operation even in extreme environmental conditions.
• Rated impulse withstand voltage Uimp 4kV: increased resistance to impulse overvoltages, which translates into longer device life and greater installation safety.
