Overcurrent circuit breaker 6kA HN-B50/3 194886

6kA Circuit Breaker HN-B50/3 is a reliable protection for electrical installations, designed for both home and commercial use. The device effectively protects against the effects of overloads and short circuits, ensuring safety and extending the life of connected devices. This model, with a rated current of 50A and a B characteristic, is ideal for socket and lighting circuits.

Product features and application

The HN-B50/3 circuit breaker belongs to the xPole Home series by Eaton – a line of products characterized by simplicity, reliability and compliance with applicable standards. Its universal design allows for easy mounting on a TH 35 DIN rail and power supply from both the top and bottom. Double terminals (tunnel and busbar) facilitate the connection of wires or busbars. The rated short-circuit breaking capacity at 6kA at 230V and 400V guarantees effective protection even in the event of high short-circuit currents. The device is designed to operate in ambient temperatures from -25°C to 75°C, making it suitable for various operating conditions.

Advantages and benefits

• Fast response: B characteristic ensures quick tripping in case of overloads, protecting sensitive electronic devices. This is especially important in socket and lighting circuits.
• Versatility: The ability to connect wires using tunnel or busbar terminals increases installation flexibility.
• Safety: Compliance with EN 60898 standards and high short-circuit breaking capacity ensure effective protection against damage to the installation and fires.
• Durability: Made of high-quality materials, guaranteeing a long service life even in difficult working conditions.
• Easy installation: Simple construction and intuitive connection method make installation easier even for less experienced electricians.
• Status indicator: A clear red-green contact position indicator allows for a quick assessment of the circuit breaker status without the need for disassembly.
• Sealable: The sealing function in the ON/OFF position provides additional protection against accidental change of the circuit breaker status.

Design and parameters

The HN-B50/3 circuit breaker is a three-pole (3P) device with a width of 3 modules, allowing for efficient use of space in the switchgear cabinet. It has a protection class of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4kV. The cross-section of the connected conductor can range from 1 mm² to 25 mm², for both solid and stranded wires. Power losses are 14.6W at an operating frequency of 50 to 60 Hz. The pollution degree is 3, which means resistance to dust and moisture occurring in normal operating conditions. The energy limitation class is 3 – it provides adequate protection against the effects of internal device short circuits.
